Whitling Stormwater Management Program Manual Page 5 Frequently Asked Questions 1. What is Stormwater Management? When it rains, water runs off land. Stormwater Management is the way people deal with the extra volume, increased rate, and increased velocity of water that runs off land that has been developed. Refer to Chapter 3 - Hydrology and Hydraulics, page 21. 2. What is a Stormwater Management (SWM) Plan? A SWM Plan shows how a landowner or developer will handle the water that will run off the land after development takes place. The SWM Plan consists of drawings, details, calculations, and a narrative. Refer to Chapter 4 – Stormwater Management Program - Review Process, page 26. 3. When do I need a Stormwater Management (SWM) Plan? Anyone who increases the volume, velocity, or rate of stormwater that flows off the land development site may need a SWM plan. Contact your municipality to find out its requirements. 4. What is an Erosion and Sedimentation Control (E&S) Plan and how is it related to Stormwater Management? An E&S Plan shows how a landowner or developer will control erosion and sedimentation during construction on a specific site. The plan consists of drawings, details, calculations and a narrative. Sometimes development of a site does not significantly impact runoff, but when it does, a stormwater management plan must be prepared in conjunction with an E&S plan and will use some of the same facilities for proposed controls. These plans are reviewed concurrently as much as possible. For more information on E&S plans refer to the Erosion and Sedimentation Control Manual available at www.depweb.state.pa.us 5. What is a Post-Construction Stormwater Management (PCSM) Plan? A PCSM plan is a site-specific SWM plan that meets the requirements of the NPDES construction permit Section E for each site. Refer to Chapter 4 – Stormwater Management Program - Review Process, page 26. 6. What is an NPDES construction permit, and when do I need it? NPDES, or, the National Pollutant Discharge Elimination System, is a state permit that meets federal standards. An NPDES permit is reviewed by the Conservation District, and is issued by the District or DEP, allowing the permittee to move earth on a construction site. An NPDES construction permit is needed in general if the disturbed area on a construction site exceeds one acre. For more information see www.depweb.state.pa.us Westmoreland Conservation District 3/3/2007 Stormwater Management Program Manual Page 6 7. What is an MS4 permit? MS4, or Municipal Separate Storm Sewer System, is an NPDES permit and a designation applied to the storm sewer system in certain municipalities. These municipalities must obtain a permit from DEP to operate their storm sewer system. The six elements of the permit include public participation, education, illicit detection and elimination, erosion control, post-construction SWM, and municipal good housekeeping. Contact your municipality for more information. 8. Do I need Stormwater Management (SWM) approval from my municipality? Municipal approval is needed for various activities, depending on where you live and what you are doing. Each municipality is different, and you should contact your municipality BEFORE you begin any type of construction project. 9. When do I need Westmoreland Conservation District (WCD) approval for my Stormwater Management (SWM) Plan? WCD SWM approval is needed if you: 1) need an NPDES construction permit; and/or 2) are directed by your municipality to obtain it. 10. How do I start a Stormwater Management (SWM) Plan? SWM plans start with a conversation between the land developer, the Westmoreland Conservation District, the municipal engineer, and a qualified plan designer, during which various aspects of the land development are worked out. SWM is as much a part of land development as streets, utilities, and buildings. 11. Who is responsible for Stormwater Management (SWM)? Initially, the landowner/developer is responsible for activities on the land. Ultimately however, SWM may involve others; municipalities may be responsible for codes and maintenance, a designer may be responsible for the design of best management practices (BMPs), a contractor may be responsible for the installation of BMPs, and even a homeowners association may be responsible. 12. Who prepares Stormwater Management (SWM) Plans? A plan designer, working for the land-owner or developer, prepares the plan. This person may be a civil engineer, landscape architect, land surveyor, architect, or other qualified design professional. Check with your municipality for specific requirements. 13. Who is responsible for Stormwater Management (SWM) Plan review? SWM plans are reviewed by a qualified Westmoreland Conservation District (WCD) engineer, according to NPDES requirements and WCD agreements with municipalities. SWM plans are also reviewed by municipalities, DEP reserves the right to review Post-construction Stormwater Management plans (PCSM). Refer to Chapter 4 – Stormwater Management Program - Review Process, page 26. 14. Who is responsible for Stormwater Management (SWM) implementation and inspection? The landowner/developer is responsible for implementing the SWM plan. Municipalities, the WCD and DEP may conduct inspections during construction to verify compliance with the plan, and may conduct inspections afterward to determine maintenance needs. Westmoreland Conservation District 3/3/2007 Stormwater Management Program Manual Page 7 15. Who is responsible for the maintenance of stormwater facilities? The owner of the facility is responsible. In some cases this is a municipal government; in others, it is a homeowners association or a private entity. 16. What is the Westmoreland Conservation District’s (WCD) Stormwater Management (SWM) Plan review time? According to DEP regulations, WCD has 45 days to conduct the first review of an Erosion and Sediment (E&S) Control Plan. Our SWM review time is similar. Once the plan is reviewed and comments are generated, the revisions will be reviewed in the order in which they are received. Refer to Chapter 4 – Stormwater Management Program - Review Process, page 26. 17. What do soils, slopes, and vegetation have to do with stormwater? A soil with more clay and silt content will have more runoff and less infiltration than sandier soils. More water runs off a steep slope than a gentle slope. A wellvegetated surface generates less runoff than a poorly covered surface. 18. What do ordinances have to do with stormwater? Although stormwater itself is governed by natural constraints such as watershed boundaries, soil types, and slopes, Stormwater management in Pennsylvania is primarily regulated by local municipal ordinances. These ordinances are mostly limited to municipal boundaries. Each of our state’s 2500+ municipalities has the responsibility to enact and monitor its own ordinance, but regulations also exist at the federal and state levels. 19. Who is responsible for water flowing across one property from another? In general, property owners are responsible to see that they don’t increase or redirect or obstruct water flowing from one property onto another property. 20. How does a detention/retention pond function? A detention pond is like a bathtub…it has a large volume and a small outlet hole at the bottom. Stormwater rushes in from storm sewers and ditches and fills the pond up, but it can only go out slowly through the hole at the bottom. A retention pond is, technically, a pond that holds water for a longer time than a detention pond. 21. How do I make a stormwater complaint? Contact your municipality and apprise those officials of the situation. A stormwater complaint filed with the Westmoreland Conservation District must be made according to the procedure outlined on the ‘SWM Complaint Form’ found in the Appendix of this manual. 22. Someone is bulldozing, what do I do? DEP’s Erosion Control regulations (Chapter 102) govern earthmoving. If someone is moving earth, they must abide by Chapter 102 regulations, which require them to keep mud and muddy water from leaving their project site. If you have an erosion control complaint, please contact one of WCD’s E&S inspectors at the District offices, 724-837-5271. Westmoreland Conservation District 3/3/2007 Stormwater Management Program Manual Page 8 23. How is sewage related to Stormwater Management (SWM)? If you have a sewage question or complaint, you must first contact your municipality and then the DEP. Sewage is wastewater from sinks, toilets, washing machines, etc. It is regulated by DEP and by municipalities. Ordinarily, sewage should be treated by a septic system or carried away to a sewage treatment plant by the sanitary sewer. If sewage gets mixed with stormwater, serious pollution can occur. Some older towns have ‘combined sewers’ in which stormwater and sewage get mixed; these are regulated by PA DEP. 24. What is PennDOT’s role in Stormwater Management (SWM)? PennDOT is responsible for most of the storm sewers that drain the state highways. In general, this agency maintains roadside ditches, cross-drains, culverts, etc., with the goal of keeping water off of the roadway surface. If you have a project that impacts drainage on a PennDOT roadway, you may need a Highway Occupancy Permit from PennDOT. For these types of projects in Westmoreland County, contact PennDOT District 12-0 at 724-832-5387. 25. What about mosquitoes? Mosquitoes, pesky and disease-ridden though they may be, are a natural part of the ecosystem and are a vital food source for many natural predators. They breed in stagnant water; that is, water that has stood undisturbed for a week or more. A properly designed SWM BMP will limit mosquito growth by controlling the amount and area of standing water and by providing habitat for mosquito predators. For more info, visit EPA’s website: www.epa.gov and type mosquito into the search box. 26. When would I need a permit from the Army Corps of Engineers (USACE)? A permit from USACE is required when disturbance occurs to impact streams, wetlands and other water bodies that may not otherwise be regulated by DEP. Refer to the USACE permit application and checklist in the Appendix.

Westmoreland Conservation District 3/3/2007 Stormwater Management Program Manual Page 12 1. Overview INTRODUCTION Westmoreland County covers more than 1,000 square miles and receives, on average, about 40 inches of rain annually. The rolling landscape, which reaches from the Allegheny and Monongahela rivers to the Laurel Mountains, is filled with water resources such as springs, streams, and lakes; some 370,000 people; and development such as homes, businesses, shops, factories, and highways. The interaction between human activities and water resources creates conflict in the form of flooding, erosion, environmental degradation, property damage, and personal suffering. The Westmoreland Conservation District’s Stormwater Management Program was formed to lessen these conflicts. Monongahela River Westmoreland Conservation District 3/3/2007 Stormwater Management Program Manual Page 13 ORGANIZATION Conservation Districts are unique subdivisions of state government; the only local unit of government responsible for coordinating the conservation of our soil, water, land, forests, and other natural resources. Because each county conservation district develops its own programs to suit the needs of the people in its county, local citizens play an important role at all levels of district organization. Districts are governed by a volunteer board of directors made up of area farmers and other interested members of the public, each with a vested interest in the county’s natural resources. The Westmoreland Conservation District has directors who are farmers, developers, and community leaders. PROGRAMS Conservation districts promote and provide science-based conservation efforts and programs for public information and education within the county. The Westmoreland Conservation District enhances its programs by creatively linking the support of individuals, organizations, and agencies equally committed to the wise use of natural resources. Conservation district programs include: • • • • • • • Agriculture Forestry Abandoned Mine Reclamation Erosion Control Stormwater Management Watersheds Environmental Education HISTORY The Westmoreland Conservation District was launched by the Westmoreland County Commissioners on October 21, 1949. Its primary purpose was to serve county farmers by helping them to conserve their soil and water resources. During the 1950s and 1960s, the District became deeply involved in broaderbased issues, including flood prevention, an inventory of county soils, anti-litter campaigns, and land-use planning. The 1970s were a time of accelerated urbanization and growth in Westmoreland County, and programs addressing those needs—including sediment control and stormwater management—were added. The first professional manager was hired by the District in 1973. Westmoreland Conservation District 3/3/2007 Stormwater Management Program Manual Page 14 The 1980s presented a new set of challenges, including technical issues such as nonpoint source pollution, groundwater protection, and solid waste management. Increased state and county funding made it possible for the District to grow and provide technical assistance on these new issues. The last decade of the twentieth century was marked by the continuing diversification of programs and related activities. More staff was added to service the demands for both core programs and newly created ones. The District and many of its partners (Penn State Extension, Westmoreland County Agricultural Land Preservation Program, Western PA Coalition for Abandoned Mine Reclamation, and USDA offices of Natural Resources Conservation Service, Farm Service Agency, Rural Development, and Penn’s Corner Resource Conservation & Development Area) moved into a new one-stop agricultural service center to better serve county residents. Most recently, the District has expanded its services into a formalized conservation education program, and has created a number of citizen’s advisory boards, such as the Stormwater Advisory Committee, to assist it in creating programs and services that are relevant to our clients’ needs. It is the goal of the Westmoreland Conservation District board, staff, and supporters to continue to grow and change in response to the needs of our county. The Westmoreland Conservation District offices are located in the restored red 120-year-old bank barn, a symbol of traditional Pennsylvania agriculture. Surrounding the barn are stormwater management demonstrations, including infiltration pavement, a rain garden, a cistern, and a solar pump. Interpretive signs and brochures allow visitors to educate themselves in the water cycle as they stroll around the property. Please visit us and take our stormwater tour! Westmoreland Conservation District 3/3/2007 Stormwater Management Program Manual Page 15 STORMWATER MANAGEMENT PROGRAM In the late 1980s, the Westmoreland County Commissioners and the District’s Board of Directors recognized the need to resolve the conflicts between human activities and our natural water resources. Together, they established the Westmoreland Conservation District’s Stormwater Management (SWM) Program. The District SWM Program covers the entire county, spanning 65 individual municipalities and 10 major watersheds. At its outset, the District SWM program was based on the relationships of various municipalities, designers, developers, and landowners with the District and its staff. Through the years, some relationships have been formalized with a Conservation Partnership Agreement (CPA), which assigns various stormwater management, erosion control and complaint handling duties and responsibilities to the parties involved. A copy of a sample agreement is included in the Appendix. Some municipalities have established formal requirements within their ordinances for District participation in their development plan approval process. The District also has ongoing relationships with state and federal programs. PA DEP, which helps guide the District SWM program, delegated the NPDES program to county conservation districts, and gives further authority to the District in the area of post-construction SWM. The state-mandated Act 167 process, and the federal EPA’s recently begun MS4 program, both include conservation district roles. STORMWATER MANAGEMENT PROGRAM PARTNERS Westmoreland Conservation District appreciates the involvement of many partners in our Stormwater Management (SWM) program. Some of the key ones are listed below. Westmoreland County: County Commissioners have provided annual funding for this program since its inception. A technical support partnership with the County Planning Department enables us to make use of the latest GIS technology. PA DEP, Pennsylvania Department of Environmental Protection: DEP maintains various levels of environmental regulation in the area of SWM. Its NPDES permit program, delegated by an MOU agreement with the Conservation District, oversees SWM on many construction sites. DEP’s Stormwater Management Best Management Practice Manual provides much guidance for designers with regard to the use of BMPs. Through Act 167, DEP helps municipalities to develop stormwater management plans on a watershed basis. DEP also controls the Chapter 102 and 105 regulations concerning erosion control and water encroachments. Westmoreland Conservation District 3/3/2007 Stormwater Management Program Manual Page 16 PA Fish and Boat Commission: The Fish and Boat Commission has enforcement authority with regard to activities in bodies of water. Any fill, excavation, or disturbance of a stream, pond, wetland, river, etc. may fall under its jurisdiction. USACE, Army Corps of Engineers: This federal agency regulates work in streams, bodies of water, and wetlands. A Corps permit is often needed to fill or change the geometry of a drainage channel. The initial Corps permit form is included in the Appendix of this manual. US EPA, Environmental Protection Agency: This federal agency regulates water quality issues, and is the originating agency for the NPDES permit, which governs water runoff from construction sites. Municipalities: The 65 municipalities in our county each have the responsibility to regulate stormwater. Of these, about half actively regulate SWM with an ordinance and/or an agreement with the District. The District maintains Conservation Partnership Agreements (CPA) with these municipalities. Originally designated as a Memorandum of Understanding (MOU), the agreements are now designated as CPAs. The CPA sets forth responsibilities of the District and the municipality. A sample CPA is found in the Appendix of this manual. Many of the municipalities that don’t regulate SWM do not have much land development activity; however the District works with those municipalities on an ‘as-needed’ basis. Westmoreland Conservation District 3/3/2007 Stormwater Management Program Manual Page 17 STORMWATER MANAGEMENT PROGRAM GOALS The goals of the Westmoreland Conservation District SWM Program are many and change as the program evolves and grows. The goals include the following: 9 Continue to review stormwater management plans, NPDES Section E and Post-Construction Stormwater Management (PCSM) plans submitted to the District, coordinating the reviews with other District staff members (i.e. erosion control reviews), engineers, and municipal officials. 9 Continue to provide technical assistance to designers, developers, landowners and municipalities for pre-construction, construction, and postconstruction activities. 9 Work with municipalities in the county to promote proper stormwater management, develop and improve stormwater ordinances, train municipal officials, and conduct inspections. 9 Continue to promote Conservation Partnership Agreements (CPA) with municipalities in the county, working closely with those already participating in a CPA, and working to establish agreements with all of the municipalities in the county. 9 Promote continuing education in the field of stormwater management, keeping District staff and the associates of the District at the forefront of current best management practices as well as innovations and developments in the field of stormwater management. 9 Be proactive, not reactive, in the conservation of water resources. 9 Increase public awareness by educating the public about stormwater management concerns, low-impact development, and best management practices. 9 Maintain the District Stormwater Advisory Committee to suggest improvements to the stormwater management program for District board consideration, helping to maintain the program as an effective resource for the county. 9 Establish additional funding sources to improve ongoing stormwater management operations. 9 Establish a project fund for the design, implementation and construction of stormwater management projects important to the conservation of the natural resources in Westmoreland County. Westmoreland Conservation District 3/3/2007 Stormwater Management Program Manual Page 18 2. People The singular hallmark of Westmoreland Conservation District’s long environmental stewardship efforts has always been professional, knowledgeable and effective service. Guided by policies and priorities established by the District Board of Directors, the SWM program staff keeps pace with the demands of development in the county. The District must maintain this staff to meet current as well as long-term needs. The staff is advised by the Stormwater Advisory Committee, and currently includes a hydraulic engineer, a technical administrative assistant and a stormwater technical assistant. WCD BOARD OF DIRECTORS The Westmoreland Conservation District Board of Directors is a group of interested volunteers representing Westmoreland County. Each is individually appointed to the board by the County Commissioners. They are responsible for overseeing all the program areas that the District is involved in and have the final say on what happens in the District SWM Program. HYDRAULIC ENGINEER The hydraulic engineer is the key to the SWM program and is trained in the principles of hydraulics and hydrology, and has experience in the field of stormwater management. This person is a registered Professional Engineer, and participates regularly in stormwater-related educational activities to maintain skills. The hydraulic engineer maintains strong relationships with the regulated community, municipalities, and other environmental agencies. The engineer reviews plans, provides technical assistance, responds to complaints, and makes site visits. Technical assistance involves working with municipalities to create and improve SWM ordinances, having input in county-wide stormwater plans, and responding to inquiries from designers, developers, watershed groups, and landowners. TECHNICAL ADMINISTRATIVE ASSISTANT Assisting the hydraulic engineer, the technical administrative assistant keeps track of SWM plans, organizes files, and sends and files correspondence. This person is knowledgeable in the area of SWM to the point of being able to coordinate the District SWM plan review process with the regulated community, Westmoreland Conservation District 3/3/2007 Stormwater Management Program Manual Page 19 and to determine administrative completeness of plan review applications. This person also provides timely responses to various SWM program questions that may arise. The technical administrative assistant also provides services to other District programs. STORMWATER TECHNICAL ASSISTANT The SW technical assistant helps the hydraulic engineer in all facets of the SWM program. The assistant has some stormwater education and or practical experience, but does not need to be a registered Professional Engineer. The assistant participates regularly in stormwater education activities to maintain current skills. The assistant conducts preliminary reviews of submitted SWM plans, makes site visits to assess stormwater complaints, and provides technical help to designers, developers, landowners and municipal officials. The SW technical assistant also works cooperatively with other District programs as needed. STORMWATER ADVISORY COMMITTEE The Stormwater Advisory Committee is comprised of associates of the District and volunteers from the Westmoreland County community. Committee members are designers, developers, landowners, municipal representatives and other interested people. The committee meets a few times each year to review the policies and practices of the District SWM program and to make recommendations to the Board of Directors to guide the program into the future. Westmoreland Conservation District 3/3/2007 Stormwater Management Program Manual Page 20 3. Hydrology and Hydraulics The twin issues of hydrology and hydraulics are at the heart of District’s Stormwater Management (SWM) program. Hydrology, the study of how the water cycle interacts with the environment, addresses the issues of precipitation, infiltration, runoff, evaporation, and transpiration. Hydraulics, the study of how water flows in pipes and channels, relates to the issues of storm drainage, stormwater controls, and flooding. Effective SWM recognizes the inter-relation of these factors and attempts to replicate as much as possible their natural processes. The Hydrologic Cycle There is no “new” water. The same drops are recycled, in different ways…sometimes as water vapor (steam or clouds)… sometimes as liquid (rain, a puddle, or a lake)…sometimes as a solid (snow, hail, or ice). In Westmoreland County we receive about 40 inches of precipitation each year. In the natural hydrologic cycle, more than half is returned skyward by evapotranspiration – the process by which plants and the sun lift water vapor into the air. Under natural conditions, several inches of rain will run off the land, and several will soak into (infiltrate) the soil. Westmoreland Conservation District 3/3/2007 Stormwater Management Program Manual Page 21 HYDROLOGY Westmoreland County receives about 40 inches of precipitation annually. In our county, the rainiest months are in the late spring and early summer, and the driest are in the fall and winter. More than 80% of our rainstorms deliver less than ½ inch of rainfall. In Westmoreland County, human activities, such as land development, do not significantly affect annual precipitation rates. Evaporation and transpiration, known as ‘evapotranspiration’, are nature’s way of lifting water into the sky. Driven by the heat of the sun and the work of plants, evapotranspiration can account for more than half the uptake of our annual rainfall. Natural evapotranspiration is generally less in winter than in summer. An often unrecognized impact of land development is the reduction of evapotranspiration, due to the loss of plants and trees. If less water is raised back into the sky, more water must run off over the surface of the land. Limiting paved areas and using a ‘green roof’ on a building can help to replicate this important function. Infiltration of rainfall is the ‘unseen’ part of the hydrologic cycle. In this county, our infiltration rates are low due to our steep, silty and clayey soils, but over the course of a year, roughly 1/5 of our rainfall may infiltrate in a natural area. Water that soaks into the ground is available later on for use by trees and plants. If the water passes deeper into the earth it supplies drinking water wells. Groundwater also reappears as springs or seeps, and will keep small streams and ponds fresh during summer. Land development reduces infiltration in two ways: it compacts the soil, eliminating the small voids and passageways for downward movement of water; and it covers the soil surface with impervious features such as roofs and streets. The result of less infiltration is less groundwater available for other uses, and a loss of baseflow in streams. Properly designed infiltration devices can restore some of this lost function. Runoff is the most visible component of our county’s hydrologic cycle. Our county’s streams and creeks are often swollen following a rainstorm. If the rate of rainfall is high, then there will be more runoff. Other factors influencing runoff are soil type, land cover, and slope of the land. Engineers must take all these factors into consideration when designing a stormwater management system. Land development will increase the volume of runoff, sometimes even doubling the amount of water leaving a site. Development activities also increase the velocity of runoff, which can cause erosion. Most effective SWM programs deal with both the increase in volume and velocity of runoff.

Land development changes the flow paths of water, and good SWM must deal with these changes. Water flowing over established grass, or through dense brush, will be hindered by the resistance of the plants and surface material. On the other hand, water flowing off a roof or parking lot gathers speed, since it encounters very smooth surfaces. Once flowing water reaches a channel, the same factors operate. A natural stream in our county might have a velocity of about four or five feet per second, whereas water flowing in a smooth pipe or concrete-lined channel might have two or three times that speed. High-speed flow causes erosion of the land and stream channels. It can also lead to flash flooding — a lot of water rushing downhill that ends up in the same place at the same time. Stormwater management attempts to control the speed of flowing water through the preservation of natural flow paths, or by use of rock or grass-lined open channels instead of pipes. A trapezoidal drainage channel stabilized with vegetation Westmoreland Conservation District 3/3/2007 Stormwater Management Program Manual Page 24 STORMWATER MANAGEMENT AND BEST MANAGEMENT PRACTICES Stormwater management is the design and implementation of systems to control volume, peak rates and water quality of Stormwater runoff. To control these factors of stormwater runoff, designers specify Structural Best Management Practices*, or BMPs. These BMPs fall into three categories: • peak rate control, • volume control, and • water quality control. Subsurface infiltration retention tanks being installed The ‘older generation’ of structural stormwater BMPs were designed for peak rate control only—examples would be a dry detention pond or an underground tank. A pond or tank can receive high flows, store the volume for a period of time, and release the volume at a controlled rate. The ‘rate control only’ type of BMP has only limited value, and cannot replicate the complexity of the hydrologic cycle described in the previous section of this manual. Volume control and water quality control BMPs attempt to address the imbalances in the water cycle created by development. A volume control BMP will remove water from the runoff path entirely, usually by infiltrating it into the ground, as with an infiltration trench, or sometimes by evapotranspiring it back up into the sky, as in the case of a green roof. Water quality BMPs treat pollutants in stormwater by a combination of settling, filtering, and biological methods. An additional type of BMP, is to prevent the generation of excess stormwater in the first place, by applying low impact development principles, or ‘non-structural best management practices’* to land development. For example, reducing street widths, reducing the size of parking lots, and designating certain areas of a site as permanently untouched areas, will head off a stormwater problem before it ever begins. The basic principles of low impact development or non-structural best management practices (BMPs) for stormwater management should be Westmoreland Conservation District 3/3/2007 Stormwater Management Program Manual Page 25 incorporated into the site design process. During site evaluation and design the following principles should be considered and integrated into the process: • Using existing natural stormwater management systems on a site and integrating them into the proposed development by identifying environmentally sensitive resources and assessing the existing site hydrology before site design. • Designing proposed developments to prevent or at least reduce stormwater runoff by clustering and reducing building footprints, reducing impervious surface area, and minimizing earth disturbance. • Treating Stormwater runoff close to the source by creating smaller watershed areas, flattening slopes and lengthening flow paths, and maintaining the natural open drainage system. Bank barn sited to take advantage of site slope Vegetated swale for roadway drainage Strategies for low-impact development include the non-structural as well as the structural BMPs to handle the volume and peak rate reduction and the runoff water quality. Structural BMPs for low-impact development include: • Pervious pavements • Infiltration basin, trench, or subsurface infiltration bed • Rain garden or bioretention basin • Dry well or seepage pit • Vegetated swale or filter strip • Infiltration berm and retentive grading Westmoreland Conservation District 3/3/2007 Permeable paving allows infiltration Stormwater Management Program Manual Page 26 • Vegetated roof • Capture and reuse of rooftop runoff (i.e. cistern) • Constructed wetland • Wet pond/retention basin with a forebay • Dry extended detention basin with a forebay • Subsurface retention/infiltration chambers • Water quality filters and hydrodynamic devices Forebay for a retention basin The benefits of utilizing these low impact development principles and techniques are many. In addition to lowering peak discharge rates and reducing stormwater runoff, a low-impact design creates a hydrologically functional site, improves water quality and aquifer recharge and can even reduce the burden on combined sewers and reduce construction costs. • For an in-depth discussion of structural and non-structural BMPs, please refer to Pennsylvania’s Stormwater Management BMP Manual, published by DEP in 2006.

Stormwater Management Program The Westmoreland Conservation District Stormwater Management (SWM) Program reviews NPDES Post-Construction Stormwater Management plans (PCSM), and other stormwater management plans requested by county municipalities under a CPA agreement. The program also provides technical assistance, performs site inspections and handles stormwater complaints. The SWM program works in conjunction with the District’s Erosion and Sedimentation Control (E&S) program and DEP’s NPDES program. A SWM plan is prepared by a qualified designer for a landowner or developer to show how water runoff from the property will be handled after development takes place. SWM plans are not routinely required for logging, well-drilling, or agricultural projects, but some municipalities may require it. STORMWATER MANAGEMENT PLAN REVIEW PROCESS The goal of the review process is to provide the regulated community with an accurate, timely and constructive review of the plans submitted. Please refer to the Stormwater Plan Review Process flow chart on page 31. The review process begins with the completion of the District’s application and checklist and the submission of a SWM plan (and required fee as listed on the fee schedule in the Appendix). The submission will be checked for administrative completeness, including the presence of all the required components of the plan and the additional submission of an E&S plan and an NPDES Permit as required. Applicants of incomplete plans will be notified of the deficiencies in a timely manner, and incomplete plans will not be reviewed until all necessary components are received. See the Appendix for a copy of the application, checklist, fee schedule, and a sample administratively complete letter. Westmoreland Conservation District 3/3/2007 Stormwater Management Program Manual Page 29 Administrative Elements The SWM review process for administrative completeness includes the following elements. • • • • • Application form, properly filled out NPDES Permit Application, if required, properly completed with signatures Fee, as required Stormwater Management Plan including o Narrative o Site plans, location map, and topographical information o Worksheets and calculations o Details Post Construction Stormwater Management Plan (PCSM) if required with supporting plans and calculations If an NPDES Permit as well as an Erosion and Sedimentation Control Plan are required, the items listed on their checklists must also be included in the submission to the District. See the Appendix for copies of these items. Administratively complete plans received are entered into the District computer database and are placed on the review pathway. Plans are reviewed in the order they are received. The SWM review process is coordinated with the District’s E&S review process, and is expected to take less than 45 days. Technical Elements The SWM review process for technical completeness routinely focuses on the following elements. • • • Site plans, including but not limited to: o Scale, north arrow, and location map o Soils and existing and proposed topographical information o Location of all buildings, pavements, vegetation and stormwater management facilities Narrative explaining the site’s particular SWM Best Management Practices, including but not limited to: o Description of proposed site development o Description of proposed stormwater management plan o Explanation of whether it is part of an existing NPDES permit or prior stormwater management plan Precipitation and storm data from a reliable source such as: o TR-55 o NOAA atlas o PennDOT Westmoreland Conservation District 3/3/2007 Stormwater Management Program Manual Page 30 • • • • • • • • An appropriate method of runoff calculations o TR-55 or TR-20 (recommended for larger watersheds) o Modified Rational Method (recommended for smaller watersheds) o Commercially available stormwater calculation software Worksheets and sample calculations, correctly completed such as o Correct CN value for site soils and subcatchment areas o Correct n values for surface cover o Worksheet 3 from TR-55 for Tc (time of concentration) o Hydrograph for pond storage, outlet orifices Appropriate design consideration of stormwater velocity and volume especially with respect to: o Water quality volume o Structural energy dissipaters such as riprap, drop manhole, offset inlet/outlet o Pipe slope, tops and inverts of structures Inclusion of detention/retention systems, and consideration of bioinfiltration systems such as: o Micropool extended detention pond o Wet extended detention pond o Wetland o Infiltration swale Details of stormwater management facilities including but not limited to: o Detention/retention facilities o Inlet and outlet structures o Energy dissipaters o Anti-seep collars o Emergency spillway Consideration of water quality by the use of facilities such as: o Forebays for detention/retention ponds o Wet pools, with safety and aquatic benches and proposed vegetation o Vegetated swales with or without check dams o Cisterns o Commercially available products Consideration of downstream effects of released water especially with regard to: o Proposed release rates o Location of proposed facilities o Off-site flow paths Properly completed current NPDES Section E and PCSM, if required, especially: o Appropriate explanation of BMPs in item 2 o Correct calculations in Box 4 o Complete list of BMPs shown in Box 5 with results of calculations Westmoreland Conservation District 3/3/2007 Stormwater Management Program Manual Page 31 Applicants who submit SWM plans are expected to be familiar with applicable federal, state and local regulations governing their project. Of particular note are standards expressed by NPDES regulations and by the PA Stormwater Management BMP Manual, [soon to be published by DEP]. Plan Review Comments and Inadequacies SWM Plan review comments are based on the aforementioned requirements, and focus on accepted SWM principles and standard engineering practice with an emphasis on water quality and conservation. Comments are sent to the applicant and copies are sent to the municipality and the municipal engineer. SWM comments may also be sent to cooperating agencies or other interested parties (i.e. watershed associations, municipal authorities, etc.) as requested. In general, a SWM plan that receives many technical comments will be considered to be Not Adequate. See the Appendix for a sample copy of the standard review comment letter. A plan may be deemed adequate with comments, but not with inadequacies. Final stormwater plan approval falls under the jurisdiction of the municipality. Final NPDES – PCSM plan approval comes from the District or DEP. Plan Revisions A SWM plan revised according to the District SWM program review comment letter will be reentered into the review pathway and will be reviewed in the order it was received. Designers submitting revisions are requested to provide fresh copies of whichever of the SWM plan elements they have revised, along with a letter specifically answering each of the technical or administrative deficiencies that District identified in the review comment letter. Designers are encouraged to arrange meetings or site visits with District staff during the design and review process. Westmoreland Conservation District 3/3/2007 Stormwater Management Program Manual Page 32 Plan Adequacy Plan adequacy means only that the District’s review process has not identified any substantive deficiencies in the various elements of the plan that we have reviewed. Adequate SWM plans will receive a letter stating the following. THIS PROJECT HAS (HAS NOT) BEEN FOUND TO CONTAIN THE APPROPRIATE PLAN ELEMENTS. The District’s review of this plan does not constitute an authorization of construction activities, earthmoving, or land use changes. Before such activity can begin, any pertinent local, state, and federal reviews, approvals, and permits must be secured from the agency having specific permitting authority. Responsibility for final approval or disapproval of the stormwater management plan rests solely with the municipality requiring this review. Applicants must understand that the District’s letter of adequacy does not constitute final approval to begin construction; that responsibility lies with the municipality in which the project is located. See the Appendix for a sample copy of the standard technically complete (adequate) letter.

Construction of a stormwater management basin will require proper erosion controls, and if the SWM basin is part of the erosion control plan, it must be built according to the approved plan. If a portion of a stormwater system is near or in a regulated body of water, it may need a Chapter 105 permit. For example, a detention basin on a drainageway of more than 100 acres will need a Dam Safety permit, and a storm sewer outfall into a stream may need a GP-4, Intakes and Outfalls permit. Refer to the Appendix for a List of General Permits. The role of the Westmoreland Conservation District in the relationship between Chapters 102 and 105 and stormwater is to advise designers of their responsibilities; to review plans for any potential regulatory conflicts; and, if necessary, to withhold letters of adequacy unless these conflicts are properly satisfied. PA DEP regulates erosion and sediment (E&S) control by its ‘Chapter 102’ rules and regulations. These address only E&S controls; that is, they do not address stormwater management, because the DEP separates those two topics. DEP’s Chapter 102 regulations require anyone moving earth to control erosion so that mud and muddy water do not leave a site and enter ‘Waters of the Commonwealth’, thus causing pollution. An erosion control plan is required, and Conservation District approval is required if certain parameters are met. The District reviews a few hundred of these plans each year. DEP also delegates inspection authority to conservation districts to visit earthmoving sites, make inspections, and to refer a site in violation of the E&S regulations to DEP for enforcement. DEP will not ‘enforce’ a construction site for violations of stormwater rules, but only for erosion violations. Certain incidents could however end up in a civil action. Municipalities are responsible for the enforcement of any stormwater violations within their jurisdiction when construction is complete and stabilized. DEP’s ‘Chapter 105’ rules and regulations govern Dams and Water Obstructions and Encroachments. Under these regulations, a permit is needed to modify the course, cross section, or other characteristics of a regulated body of water, including a stream, pond, river, wetland, creek, lake, etc. The Chapter 105 rules may not govern stormwater management if the DEP does not consider it to be an encroachment or obstruction. In our county each year, many people receive Chapter 105 permits for driveway culverts, utility line crossings, Westmoreland Conservation District 3/3/2007 Stormwater Management Program Manual Page 35 bank stabilization, bridges, etc. DEP delegates certain aspects of the 105 program to certain conservation districts, and the districts refer violations to the DEP for enforcement. DEP does not ‘enforce’ stormwater problems under the Chapter 105 rules. NPDES CONSTRUCTION PERMIT The Westmoreland Conservation District reviews all National Pollutant Discharge Elimination System (NPDES) Construction Permit applications submitted for administrative completeness as well as technical correctness. Section E (of the current permit), relating specifically to SWM, must be filled out completely and correctly for the NPDES application to be sent onto to DEP for approval. See the Appendix for a copy of an NPDES construction permit application. TECHNICAL ASSISTANCE Introduction With the goal of making wise use of our county’s natural resources, the Westmoreland Conservation District encourages all parties involved with stormwater management (SWM) to seek technical assistance throughout the review process. Available by request, technical assistance includes pre-design site visits, design aid visits, construction site visits and in-office meetings. Site visits are explained further in the Site visits, Inspection and Complaint Handling section on page 36. The District SWM program staff is available by phone or at the District office to answer any questions regarding site development, stormwater management and best management practices as they relate to each site submitted for review. To the Regulated Community Providing appropriate technical assistance to the regulated community is key to the success of the District’s SWM program. The help provided is of the ‘teach a man to bake’ type; that is, if one gives a man a pie he is fed for a day, but if one teaches a man to bake he can feed himself. One of the program’s goals is to increase the personal knowledge of SWM designers in the use of sound SWM principles. To this end, the technical assistance given will be prioritized as follows: first, seminars and training workshops; second, personal interactive sessions with individuals; and third, corrective training in problem areas. Our SWM design clients are encouraged to attend the many seminars and workshops that we make available on a regular basis. For particular problems and assistance with Westmoreland Conservation District 3/3/2007 Stormwater Management Program Manual Page 36 site design, our SWM staff are available by phone, mail, Internet, office, or site visits. Our staff will also teach various SWM principles and procedures to clients. But for those clients who do not attend workshops and who do not show personal progression in SWM proficiency, our assistance must of necessity be limited due to other pressing needs. The Westmoreland Conservation District Stormwater Management Program’s technical assistance is not designed nor intended as a substitute for professional services required by an applicant. Applicants are responsible for engaging knowledgeable professionals to prepare their plans and applications and to advise them throughout the review and approval process. Workshops: SWM information and training sessions will be scheduled on a regular basis; the goal is to have at least one general SWM session per year for the regulated community. Pre-Plan Meetings: SWM designers are encouraged to come to the District office to discuss proposed plans for their sites. District resources (maps, technical guides, and data) and staff will be available for scheduled appointments and for brief unscheduled consultation. Pre-plan meetings will often identify potential problems and solutions before they become serious. SWM designers wishing to schedule meetings should first gather all available information on their project. Pre-Plan Site Visits: For larger or more complex sites, or where SWM problems are known to exist, a site visit will be of tremendous value. District staff will be available on a scheduled basis for such visits. SWM designers wishing to schedule such visits should gather all available information and contact their municipal officials and if needed the landowner/developer. In-Office Technical Assistance: During the design phase of a project, the District staff is available for consultation with landowners and/or designers to determine the best management practices for each individual site. To Municipalities Technical assistance will be provided to municipalities free-of-charge, in conjunction with that assistance provided to them by their consulting engineer. The District’s role is to provide help and guidance, not to replace or supplant the services of a regular professional—one of our SWM program’s core goals is to enable municipalities to develop their own SWM capabilities as much as possible. Municipal assistance will be given first to municipalities with which the District has a CPA (MOU) and then to all others. Municipalities are encouraged to enter in to a CPA with the District. A sample CPA is in the Appendix of this manual. Westmoreland Conservation District 3/3/2007 Stormwater Management Program Manual Page 37 To the Public Technical assistance will be provided to the public free-of-charge, in cooperation with their municipality. The District’s role is to provide help and guidance, not to replace or supplant the services available from a municipal government. Technical assistance will be given to citizens with the understanding that the District has no authority to require others to take action and that the District has no responsibility to them beyond help and guidance. In general, members of the public with SWM problems may receive recommendations from the District, and if they need further engineering help they should hire their own consultant. Members of the public desiring District technical assistance are expected to gather all available information and contact neighboring property owners as needed before contacting the District. To Other Agencies The Westmoreland Conservation District works cooperatively with all federal, state, and local government agencies and other conservation-oriented groups, including watershed associations. The long-term relationships we enjoy with USDA-NRCS, PA DEP, and many conservation groups form a strong foundation for many of our programs. Our technical assistance will be provided to these groups free-of-charge as time and resources permit. Other agencies and groups are expected, as usual, to gather as much information as possible prior to contacting the District. Note: The District’s SWM program operates parallel to the District’s Erosion Control program, and all efforts to coordinate between these programs and other District programs will be made. Westmoreland Conservation District 3/3/2007 Stormwater Management Program Manual Page 38 SITE VISITS, INSPECTIONS, COMPLAINT HANDLING The Westmoreland Conservation District places a high program importance on site visits. Site visits will help SWM designers by giving them new perspectives on problems, will enable our review staff to more effectively check plans, and in general will promote a more effective and efficient SWM process. Time spent on a site visit is time that usually won’t have to be spent during the plan review process puzzling over drawings and details. Pre-Design Site Visits. Pre-design site visits (PDSV) are strongly encouraged for larger or more difficult sites; that is, urban sites or places where known flooding or SWM problems exist. The District SWM staff will make these visits free-ofcharge with cooperating designers and a representative of the municipality. The purpose of the PDSV is to 1) identify resource areas that need to be protected; 2) identify existing flooding or water problem areas; 3) determine options for SWM; and 4) determine applicable BMPs. To request a PDSV, the designer must assemble all known information about the site, contact the municipality, and have some idea of what the owner desires to do. Design Aid Site Visits. Design aid site visits (DASV) will be made during the design phase of a project, often during or after the first plan review. The District staff will provide technical expertise to plan preparers; however, the staff will NOT do a design for the preparer. Designers are expected to be familiar with the site, with the calculation methods they use, and with the BMPs that they would like to use. Preconstruction Meeting. A preconstruction meeting may be held on the site in conjunction with the District’s erosion control program. The meeting should include personnel from the District’s erosion control and stormwater management programs, municipal representatives, the developer and the contractor. Construction Site Visits. Construction site visits (CSV) are made in conjunction with the municipality, the designer, the contractor, and the site owner. These visits are to verify proper installation of SWM BMPs; to address necessary adjustments in BMPs, and to deal with municipal concerns about SWM and the site. Revisions to approved SWM plans may be made during a CSV. It may be that revisions can be approved during the visit, but it may also be necessary to conduct an office review of any complex changes. CSV will usually be made in conjunction with a District Erosion Control inspection. Stormwater Management Inspections. SWM inspections are formal visits made to a site to determine compliance with an approved SWM plan. State law does not give a Conservation District the authority to conduct inspections of SWM facilities in the same manner as E&S inspections. In general, the District does not do formal SWM inspections, but will assist participating municipalities to Westmoreland Conservation District 3/3/2007 Stormwater Management Program Manual Page 39 1) develop a municipal inspection program; 2) train and instruct municipal officials in SWM inspection; 3) make some limited SWM inspections and 4) to monitor and update a municipality’s SWM inspection program. Complaints and site visits. In response to citizen complaints about stormwater management (SWM) concerns, the Westmoreland Conservation District staff may make site visits. Certain preparatory steps must be taken by the complainant before WCD will be able to make a visit. First, the complainant needs to make the following information available to the District staff: nature of the problem; location of site; directions to site; names, numbers, and addresses of all involved property owners; and any drawings or other information the complainant may have. This information must be entered into the District SWM Complaint Response Form (a copy is included in the Appendix). Second, the complainant must contact his or her municipality, and discuss the SWM problem with appropriate municipal official(s), and coordinate the municipal response with the District. The District will not make SWM site visits without the knowledge or involvement of the municipality. Third, the complainant must be present at the District site visit, and make efforts to have the other parties present at the visit as well. Finally, when the District prepares a response to the visit, it is the responsibility of the complainant to coordinate action on that response; District staff will make technical recommendations to remedy a problem but cannot be responsible for the completion of proposed actions. Urgent stormwater complaints: The Westmoreland Conservation District is not an emergency response agency nor is it a stormwater regulatory agency. Our technical assistance is for long-term, permanent solutions to ongoing stormwater problems. Urgent erosion control complaints should be referred to the Westmoreland Conservation District erosion control specialists. Urgent flooding complaints should be brought to the attention of local emergency management officials such as the local fire department. Westmoreland Conservation District 3/3/2007 Stormwater Management Program Manual Page 40 COMMON PITFALLS OF STORMWATER MANAGEMENT PLANS Based on years of reviewing stormwater management plans, the Westmoreland Conservation District SWM program staff has found the following mistakes or misconceptions to be repeated. • • • • • • • Plastic risers should not be used on detention ponds, as without proper anchoring, they will float. Grouted rock rip-rap does not work, as it is seldom installed properly and actually increases water velocity instead of decreasing it. Silt fence should not be installed in swales. Vehicular access should be provided to all detention ponds. A fenced pond should have a gate. Designer does not double-check the calculations and misses obvious errors. Energy dissipaters incorrectly designed for volume and velocity. Incorrect relationship of top and invert elevations on inlets pipes and storage structures. The District SWM staff also makes the following recommendations to designers in the design and layout of SWM systems to improve design, lessen costs, and improve water conservation and quality. • • • • • Keep runoff on the surface as much as possible to allow for evapotranspiration and infiltration before sending runoff into an underground system. Use vegetated swales at shallow slopes as often as possible, using check dams in swales with greater slopes to slow the runoff. Stormwater management ponds can be unsightly detriments to a new development, but with proper design, siting, and landscaping, they can become assets instead. Stormwater management ponds should have forebays to promote infiltration and to minimize the extent of maintenance to remove trash, debris and sediment. Allow access and extra room around ponds for maintenance.

Continuing Education Programs Education is one of the Westmoreland Conservation District’s core values. The District’s conservation education program includes classes, workshops, and tours on a variety of conservation subjects – from agriculture to stormwater – and it presents them in ways that are relevant for both technical audiences and the general public. Among the specific stormwater management offerings are annual workshops that promote SWM innovation and Best Management Practices (BMPs). Tours also are offered to area locations that have employed stormwater management techniques that are especially groundbreaking or effective. Many education offerings have limited space, and so advance registration is required. There may also be a nominal fee. Engineers’ Workshop – Each year in late winter or early spring, the District sponsors the Engineers’ Workshop to promote BMPs and innovations in SWM and E&S controls. Contractors’ Workshop – Each year, the District sponsors the Contractors’ Workshop to educate contractors on BMPs for SWM and E&S. Other education programs sponsored by the District include continuing education programs for teachers, watersheds associations, etc. These programs are offered periodically or as they are requested by special interest groups. The District will consider the promotion of any program related to the conservation of our natural resources. All education programs hosted by the District are offered at a reasonable fee for attendees to cover the program costs. The District is pursuing accreditation by various professional organizations to provide continuing education credits for the licensed professionals that attend the programs. For specific information on upcoming education events, call the Westmoreland Conservation District at 724-837-5271 or visit our website at www.wcdpa.com Westmoreland Conservation District 3/3/2007 Stormwater Management Program Manual Page 43 Westmoreland Conservation District 3/3/2007 Stormwater Management Program Manual Page 44 6. Homeowner’s Guide to Stormwater Management Understanding stormwater and how to protect your home and the environment DEFINITION: Stormwater runoff is water from rain or snow melt that does not soak into the ground. It flows over rooftops, paved areas, bare soil and sloped lawns. Hydrologic cycle PROBLEM NO. 1: Improper slopes and elevations around your home can cause stormwater runoff to lay against building foundations causing seepage and movement, lay in low spots becoming stagnant and attracting mosquitoes, or even run off too fast causing erosion and further problems for neighbors. SOLUTION: Proper site grading, landscaping and stormwater management controls. • • • • • • Slope the ground gently away from the foundation Keep steep slopes to a minimum Seed or plant bare areas Reduce paved areas and use permeable pavements Collect roof water in rain barrels or rain gardens Plant low lying areas and swales with moisture loving plants and groundcovers Rain Garden Westmoreland Conservation District 3/3/2007 Permeable Pavement Stormwater Management Program Manual Page 45 Rain Garden Wet Tolerant / Native Plants Rain Garden Moist Tolerant / Native Plants Scientific Name Scientific Name Grasses Carex lurida Elymus virginicus Perennials Asclepias incarnata Eupatorium fistulosum Lobelia cardinalis Phlox maculata Rudbeckia lacianata Verbena hastata Shrubs Aronia melanocarpa Cornus amomum Ilex verticillata Physocarpus opulifolius Salix sericea Vaccinum corymbosum Viburnum acerifolium Common Name Lurid Sedge Virginia Wild Rye Swamp Milkweed Joe-Pye Weed Cardinal Flower Phlox Cutleaf Coneflower Blue Vervain Black Chokeberry Silky Dogwood Winterberry Ninebark Silky Willow Highbush Blueberry Maple-leaved Viburnum Grasses Panicum virgatum Schizachyrium scoparium Sorghastrum nutans Perennials Asclepius syrica Aster novae-angliae Geranium maculatum Helianthus sp.

The polluted stormwater runoff flows into storm sewer systems that flow, untreated, into streams, rivers, ponds, wetlands and lakes, destroying habitats for fish and vegetation and degrading clean water supplies. SOLUTION: Reduction of pollutants in the stormwater runoff. • • • • • • Learn proper application of fertilizers and pesticides Provide safe storage and disposal of all potential pollutants Avoid deicers by using sand and physically chipping ice Compost grass clippings, garden waste and leaves Keep litter cleaned up Provide rain gardens and established landscaped areas Polluted stormwater runoff Westmoreland Conservation District 3/3/2007 Stormwater Management Program Manual Page 46 Compost bin Rain barrel Before starting any major earth disturbance, homeowners must first contact their municipality to determine if an NPDES Construction Permit application or a formal engineered plan submission is required.

Many activities near Waters of the Commonwealth also require a permit or approval. WAIVER Certain activities in Waters of the Commonwealth may have the requirement for a permit waived. These include but are not limited to 1) encroachments in a stream with drainage of less than 100 acres; 2) dams less than 3 feet high and 50 feet long used ‘for fish and fishing purposes’; 3) dams less than 15 feet high, with less than 100 acres of tributary drainage, and less than 50 acre-feet of storage; 4) certain maintenance activities. Waivers usually do not apply to work in Wetlands. Some waivers are automatic; other situations may require a written waiver from DEP. GENERAL PERMIT General Permits are for projects which fit pre-determined parameters established by DEP. Limitations include project size and the drainage area of affected bodies of water. GP’s are issued by the DEP SWRO, or by the Conservation District. SMALL PROJECTS PERMIT The Small Projects Permit is used for work which does not qualify for a General Permit, and which also does not impact Wetlands. It is for projects which “will have an insignificant impact on safety and protection of life, health, property, and the environment.” Three categories of Small Projects are Minor Bridge and Culvert Projects, Minor Work in Stream Channels, and Small Structures and Limited Activities in Floodways. Examples of such permitted activities include golf cart bridges, storage sheds, and restoration of stream channels blocked by sediment. Small Projects Permits are issued by DEP. JOINT PERMIT This permit is required for all projects which do not qualify for a Waiver, a General Permit, or a Small Projects Permit. Most work which affects Wetlands requires a Joint Permit. The Joint Permit is issued jointly by PA DEP and the US Army Corps of Engineers. Joint Permits require extensive environmental and other documentation. EMERGENCY PERMIT This permit is issued for situations posing an immediate threat to property, safety, or the environment. Contact PA DEP for authorization. CORPS OF ENGINEERS Some stream or drainage channel fills and other activities which might be either waived or not regulated by DEP, require Corps approval. Contact their Pittsburgh office for more information. WETLANDS INFORMATION Wetlands are a unique ecosystem characterized by the presence of any of three indicators—soil, water, and plants. Wetlands have hydric soil, which is wet, gray or black, mucky, or clayey. Wetlands also are saturated with water in the plant root zone and to the surface of the ground during the growing season. Wetland plants include cattails, rushes, sedges, willows, skunk cabbage, marsh marigolds, and others. Usually if two of the three wetland indicators are present, wetlands are found. The rule for working with wetlands is, first, avoid impacting them; second, minimize the impact; and third, if you must impact a wetland the damage must be mitigated, that is, the wetland must be replaced somewhere else.

Any construction activities which have not obtained NPDES permit coverage (General or Individual permit) are subject to possible enforcement actions by the Department, conservation district or to third party litigation. GENERAL INFORMATION Earth disturbance activities cannot begin until the permit authorization is received. To expedite the processing of the applicant’s request, the Department asks that you use the most up-to-date Notice of Intent (NOI) application package available. This package is designed to assist the applicant in completing the Permit NOI/application and in determining if any other environmental permits or approvals are needed for the project. Please type or print clearly when completing the form. If information needed is more than space allows, copy that appropriate page of the form and complete as required. If a question is not applicable to you or your project, check N/A in the appropriate box. Operator Requirement. When the operator/contractor and owner/developer of the facility or activity are not the same individual, corporation, partnership, or other entity, the Department recommends that both the operator and owner apply for coverage under a permit as co-permittees. If, prior to construction activities, no operator/contractor has been selected, then once selected, the operator/contractor must either be made a co-permittee or the permit must be transferred to the contractor. Failure of the operator to be added to the permit is a violation of federal law, and Department Regulations at 25 Pa. Code Chapter 102, Erosion and Sediment Control. Persons proposing earth disturbance activities which disturb five (5) or more acres, or an earth disturbance on any portion, part, or during any stage of, a larger common plan of development or sale that involves five (5) or more acres of earth disturbance over the life of the project, OR persons proposing earth disturbance activities with a point source discharge to surface waters of the Commonwealth that disturb from one (1) to less than five (5) acres, or an earth disturbance on any portion, part, or during any stage of, a larger common plan of development or sale that involves one (1) to less than five (5) acres of disturbance with a point source discharge to surface waters of the Commonwealth over the life of the project, must apply for the General NPDES Permit for Stormwater Discharges Associated With Construction Activities. A point source is defined as any discernible, confined and discrete conveyance, including, but not limited to, any pipe, ditch, channel, tunnel, well, discrete fissure, or container from which pollutants are or may be discharged. Construction activities which are not eligible for coverage under the general permit as referenced in 25 Pa. Code Chapter 92, must utilize the Individual NPDES Permit Application for Stormwater Discharges Associated With Construction Activities. These activities include, but are not limited to, construction activities that require an NPDES permit and are within "special protection" watersheds, construction activities that require an NPDES permit and which may affect existing water quality standards or threatened or endangered species and habitat, or construction activities that have the potential for toxic discharges. Pennsylvania Natural Diversity Inventory (PNDI) Project Planning Environmental Review. In order to ensure that threatened and endangered (T&E) plant and animal species will not be adversely impacted by the proposed construction activity, all applicants must submit proof that a PNDI Project Planning Environmental Review was conducted. The review can only be conducted via the internet at the www.naturalheritage.state.pa.us website. First time users will have to register at the website before conducting the review. A receipt is automatically available for printing upon completion of the PNDI review. This receipt must be submitted as part of this application form. If the PNDI review determines there are potential impacts to a T&E species, the PNDI review receipt will provide an explanation of the potential impact(s) and instructions on how to resolve the potential impact. READ AND FOLLOW THESE INSTRUCTIONS CAREFULLY. It is the applicant's responsibility to resolve potential impacts to T&E species before applying for this permit. Erosion and Requirement. Persons proposing stormwater discharges associated with construction activities should file an administratively complete and acceptable application at the earliest Sediment (E&S) Control Plan For purposes of this permit, the E&S Control Plan must contain BMPs designed to minimize point source -1- 3930-PM-WM0035 Instructions Rev. 1/2006 infiltration, to protect the structural integrity of the stream, and to protect and maintain existing and designated uses. Permittees and co-permittees are responsible for proper installation of the PCSM Plan BMPs prior to the submission of the Notice of Termination of this permit. discharges to surface waters, preserve the integrity of stream channels and protect the physical, biological and chemical qualities of the receiving water. An E&S Control Plan must be submitted to the Department or authorized county conservation district along with the completed application. If the construction activities are located in a high quality or exceptional value watershed pursuant to Chapter 93 of the Department’s regulations, the required E&S Control Plan must address the special protection requirements in the Department’s regulations at Chapter 102, Erosion and Sediment Control, Section 102.4(b)(6) for activities in such waters.

Acts 67, 68 and 127 require permit applicants to notify local governments of planned land development activities and to provide local governments the opportunity to identify any land use planning or zoning ordinance conflicts associated with the proposed project before the Department or authorized county conservation district completes its review of the NOI/permit application. Written notice must be received by the municipality and county government in which the activity is located at least 30 days before the Department may issue or deny an NPDES Permit. The written notice (letter) must also include either a completed DEP General Information Form (GIF) or answers to the 13 Land Use Information questions found in the GIF. A sample notification letter and the list of 13 Land Use Questions are included with these instructions as a convenience for the applicant. Preparedness, Prevention and Contingency (PPC) Plan Requirement.

This analysis is based on the data gathered for the background site factors and site factors inventory. The intention is to evaluate and incorporate existing site features into the stormwater management design. For example, applicants need to evaluate where most onsite infiltration naturally occurs, based on vegetation, soil types and other features. Section G. Antidegradation Analysis Section A. Site Analysis MODULE TO BE USED WITH AN APPLICATION FOR AN INDIVIDUAL NPDES PERMIT FOR STORMWATER DISCHARGES ASSOCIATED WITH CONSTRUCTION ACTIVITIES Background Site Factors, Site Factors Inventory, and Site Factors Analysis Background Site Factors-The applicant’s analysis and documentation of the background site factors is a critical step in utilizing natural site conditions to maximize the maintenance and protection of receiving waters. This enables the applicant to minimize or prevent stormwater generation and discharge at the outset in the site planning process. Site assessment includes inventorying and evaluating the various natural resource systems that define each site and pose both problems and/or opportunities for both erosion and sediment control and post construction stormwater management. This process may require field evaluation and verification of site conditions or additional data collection. GENERAL The basic concept of antidegradation is to maintain and protect existing water quality for High Quality (HQ) and Exceptional Value (EV) waters, and protect designated and existing uses for all surface waters. Permit applicants must demonstrate that all construction and post construction discharges will not degrade the physical, chemical or biological characteristics of these surface waters. Applicants can meet this requirement by demonstrating that there will be no net increase in accelerated erosion and sedimentation from the construction runoff, and that the post construction runoff volume, rate and quality equals pre-construction runoff volume, rate and quality. As required under the authority of the Department’s Chapter 93 and 96 water quality regulations, the Antidegradation Analysis Application Module must be completed and submitted to demonstrate that the applicant has provided the appropriate level of protection for surface water bodies. To satisfy the antidegradation requirements of the water quality standards regulations relating to stormwater discharges associated with construction activities, the following portions of this application apply: a site analysis (Section A); the nondischarge alternatives analysis (Section G, Part 1); and antidegradation best available combination of technologies analysis (Section G, Part 2) of the module must be completed. If the data submitted is incomplete or insufficient, it will be returned to the applicant as administratively incomplete with an explanation of why it is being returned. Site Factors Inventory- Existing vegetation and soil features are crucial to understanding land development and its potential impact on waters of the Commonwealth. Evaluation and documentation of existing vegetation, soils, permeability, surface flow patterns, critical site features, such as wetlands, floodplains, riparian areas, natural drainage ways, special habitat areas, special geological formations (e.g., carbonate), steep slopes, shallow depth to water table, shallow depth to bedrock, and other factors must be provided and analyzed. Special value areas, including wetlands, floodplains and and riparian areas, must be conserved and protected during land development. Critical, sensitive natural areas such as steep slopes, shallow bedrock, high water table areas, and other constraining features should be avoided. DEP will ensure that all water quality-related activities it permits or approves will protect Threatened and Endangered (T or E) species, its critical aquatic habitat, or any surface water upon which it critically depends. Critical habitat or dependence issues must be adequately documented by the natural resource agency so that protective provisions are included in a permit or approval. Special attention shall be given to ensuring that criteria compliance times are designed to protect the presence of all T and E species and critical habitat. -1- 3930-PM-WM0035 Instructions Rev. 02/2007 WCD discharge will not degrade the physical, chemical, or biological characteristics of the HQ or EV water. PART 1: NONDISCHARGE ALTERNATIVES ANALYSIS c. “Environmentally Sound” BMPs The requirement to consider non-discharge alternatives applies to both HQ and EV waters. The requirement to evaluate and use non-discharge alternatives must be met by an applicant proposing a project that will generate new, additional, or increased discharges to HQ or EV waters. Part 1 of the module identifies, in order of preference, some non-discharge alternative BMPs for stormwater management. The list of alternatives in the module is not exclusive or exhaustive and permit applicants can expand this list through research and/or experience with different technologies as long as applicable environmental and site factors are considered. It should be noted that non-discharge alternatives might not, under all circumstances, be the most environmentally sound option. Environmentally sound non-discharge BMPs should take into consideration factors such as sensitivity of stream uses; transitory effects on aquatic organisms; need for low flow augmentation of stream flow; sensitivity of groundwater uses in the area; secondary impacts (including suitability of geology or site conditions); management practice reliability; potential for spills and other management practice failures; and operation and maintenance considerations. a. Erosion and Sediment Control d. “Cost-Effective” BMPs Persons planning or conducting earth disturbance activities in HQ or EV watersheds must consider alternative siting, minimizing the amount of disturbance, maintaining (or installing) riparian buffer strips, and implementing other water quality protective measures including installation of multiple or redundant BMPs in an effort to enhance overall performance and maximize water quality protection. BMPs listed in the DEP’s Erosion and Sediment Control Program Manual, Policy #363-2134-008 are presumed to be cost effective for purposes of this antidegradation analysis. The BMPs identified in DEP’s Pennsylvania Stormwater Best Management Practices Manual, Policy #363-0300002, are presumed to be cost effective for purposes of this antidegradation analysis. b. Post Construction Stormwater Management e. BMPs not listed in the Department’s Manual Nondischarge BMPS must be used to control the volume and rate of stormwater discharges to prevent the physical, biological and chemical degradation of receiving surface waters. In order to meet the nondischarge alternative requirements, the applicant must first consider an alternative project site or discharge location involving water other than special protection. Where the project or discharge cannot be relocated, the applicant must then emphasize the reduction of stormwater runoff generated by development and other activities. This is accomplished through minimization of impervious cover, use of low impact development designs, use of riparian buffers, and the use of innovative stormwater BMPs that provide infiltration. If nondischarge alternative BMPs (other than ones identified in DEP’s manuals) are being proposed, the applicant must provide data to support the effectiveness of the BMP including a demonstration that it is environmentally sound and cost effective when compared with the cost of a proposed discharge. PART 2: ANTIDEGRADATION BEST AVAILABLE COMBINATION OF TECHNOLOGIES (ABACT) In circumstances where a discharge is the only viable approach, an applicant must utilize ABACT to minimize the impact of the discharge on the existing quality of receiving surface waters. The post construction stormwater management plan should be based upon a comparative pre- and postconstruction stormwater management analysis. Using this analysis, applicants can ensure that existing water quality will be protected and maintained by demonstrating that the quality, quantity and rate of postconstruction runoff equals or is less than preconstruction runoff, and that any post-construction -2- 3930-PM-WM0035 Instructions Rev. 02/2007 WCD Section H. Thermal Impacts a. Erosion and Sediment Control ABACT Special attention should be given to those BMPs that minimize the potential for causing thermal impacts to receiving surface waters caused by net increases in stormwater runoff. Some erosion and sediment control ABACT BMPs are identified in 25 Pa. Code §102.4(b)(6). Additional erosion and sediment control ABACT BMPs are identified in the module. The BMPs in §102.4(b)(6) include: (1) adopting special sediment basin requirements, (2) lining channels, collectors, and diversions with vegetation, rock, geotextile, or other nonerosive materials, and (3) immediately stabilizing disturbed areas upon completion or temporary cessation of an earth disturbance activity. BMPs listed in the DEP’s Erosion and Sediment Control Program Manual, Policy #363-2134-008, may also qualify as ABACT BMPs. b. Post Construction Stormwater Management ABACT ABACT BMPS must be used to control the volume, quality and rate of stormwater discharges to minimize the alteration of the physical, biological and chemical degradation of receiving surface waters and to ensure the protection and maintenance of water quality. The BMPs identified in DEP’s Pennsylvania Stormwater Best Management Practices Manual, Policy #363-0300-002, may also qualify as ABACT BMPs. c. BMPs Not Listed in the Department’s Manuals If ABACT BMPs (other than the ones identified in DEP’s manuals) are proposed, the applicant must provide data to support the BMPs including a demonstration that they will maintain and protect the existing quality of receiving surface waters. SOCIAL OR ECONOMIC JUSTIFICATION (SEJ) If the applicant intends to demonstrate that a degrading discharge is necessary to accommodate important economic or social development in the area in which the waters are located, the procedure identified in Chapter 10 of the Water Quality Antidegradation Implementation Guidance, Document #391-0300-002, must be fully and accurately addressed in a separate permit application submission. -3- 3930-PM-WM0035 Instructions Rev. 12/2004 -4- 3930-PM-WM0035 Rev. 11/2006 PA DEPARTMENT OF ENVIRONMENTAL PROTECTION INTERIM SITE ANALYSIS FORM SECTION A.

(Current Permittee(s) (Transferee(s)) -4- 3930-PM-WM0228 Rev. 10/2002 INSTRUCTIONS FOR THE TRANSFEREE / CO-PERMITTEE APPLICATION FORM FOR A GENERAL OR INDIVIDUAL NPDES PERMIT FOR STORMWATER DISCHARGES ASSOCIATED WITH CONSTRUCTION ACTIVITIES Who may file the Transferee/Co-Permittee Application Form: This form may be used by an applicant seeking to apply for either complete or partial operational control of earth disturbance activities at a site which are already authorized by either an Individual or General NPDES Permit. Federal NPDES Regulations at 40 C.F.R. §122.21(b) require that Operator(s) must become a permittee. An operator is a person who meets either of the following criteria: 1.) You have operational control of construction project plans and specifications, including the ability to make modifications to those plans and specifications; OR 2.) You have dayto-day operational control (supervision) of those activities at the project that are necessary to ensure compliance with the Erosion and Sediment Control Plan for the site or ensure compliance with other permit conditions, i.e., General Contractors. Subcontractors generally do not have supervisory control over earth disturbance activities and therefore usually should not become a permittee or co-permittee. If prior to construction activities, there is no operator, the owner must apply for the permit. Once the operator has been selected, the operator must use this application either to be made a co-permittee or to have the permit transferred to the contractor. Failure of the operator to be added to the permit is a violation of federal and state law and regulation. Where to file the Transferee/Co-Permittee Application Form: Send this form to the reviewing entity, either to the local county conservation district that is participating as the reviewing entity or, if the Department is the reviewing entity, to the appropriate DEP regional office, Soils and Waterways Section. When to file the Application: This application must be filed at least 30 days prior to the proposed change of ownership and/or operational control which will result in the transfer of permit responsibility, coverage and liability. Completing the Application: TYPE OR PRINT IN BLOCK LETTERS IN THE APPROPRIATE SPACES Section A.

Transferee/Co-Permittee Information - Enter the full name, address and telephone number of the individual or organization and contact person that is applying to assume operational control of construction activities at the site. The Regional Office can supply the Client ID # and Applicant Code, if known. Section E.
