4 1.0 POLICY AND GENERAL PROCEDURES A stormwater pollution prevention plan (SWPPP) shall be developed prior to submission of a registration statement. It will be implemented during the construction activity covered by the permit. The purpose of the SWPPP is to identify potential sources of pollutants that could potentially affect quality of stormwater discharges from the construction site and describe control measures used to minimize pollutants in stormwater on site. A Virginia Stormwater Management Program Permit is required from the Virignia Department of Conservation and Recreation for all land disturbing activities that disturb greater than one acre, or for land disturbing activities that disturb greater than 2,500 square feet within an area designated as a Chesapeake Bay Preservation Act Resource Protection Area or Resource Management Area. a. Registration Statement The Owner will file a complete Registration Statement for coverage under a VSMP general permit for stormwater discharges from construction activities with the Virginia Department of Conservation and Recreation and verification of coverage received from the Department of Conservation and Recreation prior to the commencement of land disturbing activities exceeding the thresholds noted above. The appropriate filing fee must be submitted to the Department of Conservation and Recreation, Division of Finance before the general permit will be issued. b. Stormwater General Permit Compliance All contractors and subcontractors will sign the certification statement contained herein indicating knowledge of and intent to comply with the stormwater pollution prevention plans. Contractor is regarded as the primary agent for ensuring compliance with the SWPPP for this construction project. The Contractor will ensure compliance with the requirements of the VSMP - Virginia Stormwater Management Program Permit For Stormwater Discharges From Construction Sites, including but not limited to the following items: Implementation, Documentation, and Inspections Necessary for Compliance with Stormwater General Permit Implementation of the SWPPP as developed for the site and in accordance with the general permit requirements with regard to erosion and sediment control, post-construction stormwater management, and other controls regarding solid materials, sediments and dust, and the demonstrated compliance with applicable State and/or local waste disposal, sanitary sewer or septic system regulations. Retention of the SWPPP, registration statement, and acknowledgement letter from the permit-issuing authority at the construction site. The SWPPP must be made available to the department and permit issuing authority for review at the time of an on-site inspection. A copy of this SWPPP must be kept in the owner s permanent project records for at least three years following submission of the Notice of Termination. Poindexter Street Streetscape Improvements Phases 3 & 4 June 17, 2009 Stormwater Pollution Prevention Plan Page 2

5 A sign including a copy of the permit coverage letter with the registration number for the construction activity must be posted at the construction entrance. This sign must also have the name of the contact person and phone number to request a SWPPP review. Amendment of the SWPPP whenever there is a change in design, construction, operation, or maintenance, which has a significant effect on the potential for the discharge of pollutants to the surface waters of the State, or if the Plan proves to be ineffective in eliminating or significantly minimizing pollutants from the construction activity. Revisions to the SWPPP shall include additional or modified control measures designed to correct problems identified. If approval by a plan-approving authority is necessary for the control measure, revisions to the SWPPP shall be completed within seven calendar days of approval. Documentation of the dates when major grading activities occur, when construction activities temporarily or permanently cease on a portion of the site, and when stabilization measures are implemented. Inspections of disturbed areas of the construction site and areas used for storage of materials that are exposed to precipitation that have not been finally stabilized, structural control measures, and locations where vehicles enter or exit the site will be conducted on either of the following schedules: (1) at least once every 14 calendar days and within 48 hours following any runoff producing storm event OR (2) at least every 7 calendar days. Reports summarizing the inspections will be made in accordance to the regulations and retained as part of the SWPPP. All contractors and subcontractors will sign a copy of the certification statement as described in the general permit before conducting any professional services at the site identified in the Plan. All certifications will be included in the Plan. The SWPPP must clearly identify the contractor or subcontractors that will implement and maintain each measure identified in the SWPPP. The SWPPP shall be revised to identify any new contractor that will implement a measure. All documents, records, reports, and other information relevant to the general permit regulations will be given to the owner following final stabilization of the site. Where the site has been finally stabilized and all stormwater discharges from construction activities that are authorized by the general permit are eliminated, two copies of a Notice of Termination will be prepared for the owner to sign and submit to the Department of Conservation and Recreation. The structural stability of the permitted facilities will be ensured. Prohibition and Reporting of Releases of Substances Other Than Stormwater Execution of reporting requirements is required in the event of non-compliance of the general permit or if any un-permitted, unusual or extraordinary discharge enters or could be expected to enter surface waters of the State. Prohibition of non-stormwater discharges except as provided for in the general permit. Appropriate pollution prevention measures for non-stormwater components of discharge will be implemented. Execution of reporting requirements of 40 CFR Part 117 (1992) and 40 CFR Part 302 (1992). In addition, the discharge of hazardous substances or oil in the stormwater discharge from the construction site will be prevented or minimized in accordance with the stormwater pollution prevention plan. Poindexter Street Streetscape Improvements Phases 3 & 4 June 17, 2009 Stormwater Pollution Prevention Plan Page 3

6 Prohibition of discharge of hazardous substances, oil, or pollutants resulting from on-site spills or releases. Management Measures and Response to Unintentional Releases All waste collection, control, treatment, management of pollutant activities and disposal facilities will be operated in a manner consistent with the general permit regulations. All feasible steps to minimize any adverse impacts to State waters resulting from noncompliance with conditions specified in the general permit will be taken. All reasonable steps to minimize, correct or prevent any discharge in violation of the general permit which has a reasonable likelihood of adversely affecting human health or the environment will be taken. c. Notice of Termination Where the construction site has been finally stabilized and all stormwater discharges from construction activities that are authorized by this permit are eliminated, the permitee will submit a Notice of Termination within 30 days after all permit authorized construction activities have been completed. The terms and conditions of the permit will remain in effect until a completed Notice of Termination is submitted. Coverage under the permit will be deemed terminated 7 days after the date the Notice of Termination is signed. Appendix D contains a copy of the Notice of Termination Form.

7 2.0 SITE AND ACTIVITY DESCRIPTION a. Nature of the Construction Activity The purpose of this project is to conduct streetscape improvements along Poindexter Street between Guerriere Street and Chesapeake Avenue in the City of Chesapeake, Virginia. The total area to be disturbed is 2.52 acres. b. Intended Sequence and Timing Of Major Soil-Disturbing Activities This project includes the following general construction elements in order of the sequence of construction: (1) Installation of erosion and sediment control measures (2) Demolition of former structures (3) Installation of new structures (4) Final stabilization c. Dates of Activities on Site The Contractor shall document the dates of major grading activities, dates when grading has temporarily or permanently ceased, and dates when stabilization measures were initiated. Appendix E of this SWPPP contains Record of Stabilization and Construction Activity Forms. d. Estimated Total Site Area To Be Disturbed The construction limits encompass an area of disturbance that is approximately 2.52 acres of land. e. Potential Pollutant Sources An Environmental Site Assessment has been performed by LandMark Design Group and will be made available to the Contractor. Elevated levels of petroleum products may be present in the soil and/or groundwater. Take necessary precautions to insure the safety of all construction workers including personal protective equipment. Dewatering, if appropriate, should be conducted and excavated soils should be lawfully disposed. Follow all VPDES requirements for groundwater sampling during dewatering. Other potential pollutant sources, such as earthwork operations during construction, vehicle fueling, and temporary sanitary waste facilities are expected to exist on-site. Storage of fertilizers or chemicals is not anticipated. f. Receiving Waters The on-site storm drain pipes drain in a westerly direction to Scuffletown Creek, a tributary of the Southern Branch of the Elizabeth River. No net increase in stormwater runoff is anticipated. Poindexter Street Streetscape Improvements Phases 3 & 4 June 17, 2009 Stormwater Pollution Prevention Plan Page 5

8 g. Location and Description of Industrial Activity Discharge No industrial activity discharge is anticipated as part of the proposed project. h. Location Map A US Geologic Survey topographic quadrangle map of the site and its one mile vicinity is located in Appendix H. i. Site Map The Poindexter Street Streetscape Improvements Phases 3 & 4 Plan is enclosed in Appendix F showing the location and limits of construction. The site map in the SWPPP should reflect current on-site conditions. As such, the map can be marked up to depict necessary items. The following features are included in the site map and comments on them are listed below: (1) Direction of Final Storm Flows & Slopes On-site drainage will drain to the stormwater pipes. Final slopes are depicted on the plans. (2) Areas of Disturbed & Undisturbed Sites Areas of disturbed and undisturbed sites will be depicted on the mapping in Appendix F. (3) Location of Major Structural and Non-Structural Control Measures Both structural and non-structural controls have been adopted for this project and are included in the Demolition and Erosion Control Plan included as a part of the Development Plan. If deviations from this plan are made on-site they should be noted on the mapping included in Appendix F. (4) Location of Stabilization Practices The location of proposed stabilization areas are shown on the Demolition and Erosion Control Plans included as a part of the Development Plan. As stabilization practices are utilized on-site they should be noted on the mapping in Appendix F. (5) Surface Waters The surface water receiving stormwater discharge is an off-site stream known as Scuffletown Creek located southwest of the site. (6) Locations Where Concentrated Stormwater Discharges to a Surface Water Stormwater discharges do not drain to any on-site surface water. Instead, the on-site storm drain collects water and directs it an existing piped drainage system, which ultimately discharges into Scufflletown Creek. Poindexter Street Streetscape Improvements Phases 3 & 4 June 17, 2009 Stormwater Pollution Prevention Plan Page 6

9 (7) Locations of Off-Site Material, Waste, Borrow or Equipment Storage Areas No off-site material, waste, borrow, or equipment storage areas are anticipated for this project. (8) Locations of Other Potential Pollution Sources Other potential pollution sources should be added to the map when they are placed on-site, and deleted from the map when removed. These sources include but are not limited to temporary fuel tanks, dumpsters, and portable restroom facilities. (9) Areas of Final Stabilization As the project is completed the site map will be updated to show areas where final stabilization has been achieved. (10) Existing and Planned Paved Areas and Buildings There are no existing or planned buildings. A majority of the site consists of sidewalks, curbs and gutters, and roadways. Therefore, a majority of the site is paved, and will be paved at the end of construction, as this is a streetscape improvements project. (11) Locations of Permanent Stormwater Management Practices Post-Construction There are no permanent stormwater management practices planned for post-construction. j. Estimate of Runoff Coefficient The runoff coefficient was estimated at 0.75 in the original SWPPP (March 23, 2006 prepared on behalf of the City of Chesapeake). The SWPPP stated that the runoff coefficient was not proposed to change after construction activities. k. Existing Site Vegetation Some trees and shrubs exist on-site. Strict adherence should be made to the clearing limits depicted on the Plans developed by LandMark Design Group. All trees not removed will be protected from construction activities as shown on the Plans. l. Total Maximum Daily Load The state waters that the project will discharge into do not have established total maximum daily load standards. Poindexter Street Streetscape Improvements Phases 3 & 4 June 17, 2009 Stormwater Pollution Prevention Plan Page 7

10 m. Impaired Waters The state water that the project will discharge into is Scuffletown Creek, a tributary of the Southern Branch of the Elizabeth River. The Elizabeth River, and its tributaries, are designated as impaired waters by the Virginia Department of Environmental Quality.

11 3.0 POLLUTANT REDUCTION CONTROLS a. Erosion and Sediment Controls Erosion and sediment control measures for this project consist of structural and non-structural controls. These measures are shown on the construction plan sheets in Appendix F with additional information in the project specifications. (1) An erosion and sediment control plan or an agreement in lieu of a plan shall be approved by the appropriate plan-approving authority for the land disturbing activity in accordance with the Virginia Erosion and Sediment Control Law ( et seq.) and regulations (4VAC50-30). Where applicable, a plan shall be developed in accordance with boardapproved annual general erosion and sediment control specifications. (2) All control measures required by the plan shall be designed, installed, and maintained in accordance with good engineering practices and the minimum standards of the Virginia Erosion and Sediment Control Law ( et seq. of the Code of Virginia) and regulations (4VAC50-30). The following additional information is provided to the Contractor for implementation of effective stabilization measures: (1) Provisions shall be made to minimize the transport of sediment onto the paved surface. Where sediment is transported onto a paved public road surface, the road shall be cleaned thoroughly at the end of each day. Sediment shall be removed from the roads by shoveling, sweeping, and transporting to a sediment control disposal area. Street washing shall be allowed only after sediment is removed in this manner. This provision shall apply to individual parcel lots as well as larger land disturbing activities. (2) Erosion and sediment control measures shall be installed and be made operational at the start of clearing operations. (3) The Contractor shall complete drainage facilities within thirty (30) days following the completion of rough grading at any point within the project. (4) Construction shall be sequenced so that grading operations can begin and end as quickly as possible. (5) Areas which are not to be disturbed shall be clearly marked by fencing, flags, signs, etc. (6) A. Permanent or temporary soil stabilization shall be applied to denuded areas within seven days after final grade is reached on any portion of the site. Temporary soil stabilization shall be applied within seven days to denuded areas that may not be at final grade but will remain dormant (undisturbed) for longer than thirty days. Permanent stabilization shall be applied to areas that are to be left dormant for more than thirty days. Poindexter Street Streetscape Improvements Phases 3 & 4 June 17, 2009 Stormwater Pollution Prevention Plan Page 9

12 B. During construction of the project, soil stockpiles shall be stabilized or protected with sediment trapping measures. The applicant is responsible for the temporary protection and permanent stabilization of all soil stockpiles on site as well as soil intentionally transported from the project site. C. A permanent vegetative cover shall be established on denuded areas not otherwise permanently stabilized. Permanent vegetation shall not be considered established until a ground cover is achieved that, in the opinion of the local program administrator or his designated agent, is uniform, mature enough to survive and will inhibit erosion. The Contractor shall reseed areas as required to achieve the above. Hydroseeding may be used in place of mulching. D. Refer to spec section ST-01 for additional requirements on lawns and grades. (7) All storm sewer inlets that are operational during construction shall be protected so that sediment laden water cannot enter the conveyance system without first being filtered or otherwise treated to remove sediment. (8) Cut and Fill Slopes shall be designed and constructed in a manner that will minimize erosion. Slopes that are found to be eroding excessively within one year of permanent stabilization shall be provided with additional slope stabilization measures until the problem is corrected. (9) Periodic inspections and required maintenance shall be provided, especially after each significant storm. The project construction superintendent shall be responsible for the installation and maintenance of all erosion and sediment control measures. (10) All temporary erosion and sediment control measures shall be removed within thirty days after final site stabilization or after the temporary measures are no longer needed, unless otherwise authorized by the local program administrator. Trapped sediment and the disturbed soil areas resulting from the disposition of temporary measures shall be permanently stabilized to prevent further erosion and sedimentation. (11) The terms and conditions of the City s VADEQ, VPDES, MS-3, and Stormwater Construction Permits, Spill Prevention Counter Measures Control Plan (SPCCP), and the Stormwater Pollution Prevention Plan shall be adhered to at all times. Temporary and permanent erosion and sediment control measures include, but are not limited to: Dust control Silt fence Silt fences are to be installed downslope of disturbed areas to filter sediment-laden runoff from sheet flow. Poindexter Street Streetscape Improvements Phases 3 & 4 June 17, 2009 Stormwater Pollution Prevention Plan Page 10

13 Storm drain inlet protection All storm drain inlets shall be protected during construction. Sediment-laden water shall be filtered before entering the storm sewer inlets. Topsoiling All new topsoil shall be class b screened topsoil. Permanent seeding All permanent seeding shall be hydroseeded. Mulching Mulch straw or fiber will be used on topsoil areas which have been brought to final grade and have been seeded. This is to protect the slopes from erosion and to retain moisture until the new grass has become fully established. Soil stabilization blanket and matting A degradable soil stabilization blanket will be provided on slopes 3:1 or greater. These measures are in conformance with the minimum standards and specifications of the Virginia Erosion and Sediment Control Handbook. Construction phase erosion and sediment controls are designed to retain sediment on-site to the maximum extent possible. Control measures will be installed, maintained and inspected by the Contractor in accordance with specifications, applicable codes and ordinances and good engineering practices. Erosion and sedimentation controls will be periodically inspected and maintained during construction and only removed once final stabilization of the site is achieved in accordance with the inspection schedule contained in the regulations. A record of these inspections will be maintained using the forms contained herein. b. Management practices (1) The plans should ensure that existing vegetation is preserved where possible and that disturbed portions of the site are stabilized. (2) The control measures must be properly selected, installed and maintained in accordance with good engineering practices and, where applicable, manufacturer specification. If periodic inspections or other information indicates a control has been used inappropriately, or incorrectly, the operator must replace or modify the control for site situations as soon as practicable and update the SWPPP in accordance with 4VAC50-60, the Final Construction General Permit, Section II C. (3) If sediment escapes the construction site, off-site accumulations of sediment must be removed as soon as practicable to minimize off-site impacts. If approval by a planapproving authority is necessary, control measures shall be implemented to minimize pollutants in stormwater discharges until such approvals can be obtained. (4) Construction debris and construction chemicals exposed to stormwater shall be prevented from becoming a pollutant source in stormwater discharges. Poindexter Street Streetscape Improvements Phases 3 & 4 June 17, 2009 Stormwater Pollution Prevention Plan Page 11

14 (5) Litter exposed to stormwater shall be prevented from becoming a pollutant source in stormwater discharges and the construction site shall be policed daily to control litter. c. Stormwater management This SWPPP is for a streetscape and drainage project. No post-construction stormwater management controls are proposed. d. Other controls (1) No solid materials, including building materials, garbage, and debris shall be discharged to surface waters of the state, except as authorized by a Clean Water Act 404 permit. (2) The Contractor shall ensure that compliance with applicable state or local waste disposal, sanitary sewer or septic system regulations is attained. (3) The Plans do not depict any on-site storage of construction or waste materials. Therefore, no materials are expected to be stored on-site. Should storage of waste materials occur appropriate sediment trapping measures will be employed. (4) An Environmental Site Assessment has been performed by LandMark Design Group and will be made available to the Contractor. Elevated levels of petroleum products may be present in the soil and/or groundwater. Take necessary precautions to insure the safety of all construction workers including personal protective equipment. Dewatering, if applicable, should be conducted and excavated soils should be lawfully disposed. Follow all VPDES requirements for groundwater sampling during dewatering. e. Applicable state or local programs The control measures implemented at the site shall be consistent with all applicable federal, state, or local requirements for erosion and sediment control and stormwater management. The SWPPP shall be updated as necessary to reflect any revisions to applicable federal, state, or local requirements that affect the control measures implemented at the site. The following plans are incorporated into this SWPPP by reference and are to be followed by the Contractor: Poindexter Street Streetscape Improvements Phases 3 & 4 Plans Poindexter Street Streetscape Improvements Phases 3 & 4 June 17, 2009 Stormwater Pollution Prevention Plan Page 12

15 4.0 MAINTENANCE AND INSPECTIONS a. Maintenance In general, all erosion and sediment control measures shall be checked after each rainfall or every fourteen days, whichever is most frequent, or alternatively, at least every seven days. These measures should be cleaned and repaired according to the following schedule: 1. Erosion and sediment control measures shall be checked regularly for undermining and deterioration and buildup or clogging with sediment. Corrective action will be taken immediately. 2. All seeded areas shall be checked regularly to see that a good stand is maintained. Areas shall be fertilized and re-seeded as necessary. 3. All temporary erosion and sediment control measures shall be disposed of within thirty (30) days after final site stabilization is achieved and vegetation is established. All control measures must be properly maintained in effective operating condition in accordance with good engineering practices and, where applicable, manufacturer specifications. b. Inspections The Contractor will accomplish inspections and the Contractor will bear primary responsibility for inspections of all E & S devices and pollution prevention measures to ensure continuing effectiveness. The inspector must be considered qualified personnel. Qualified personnel means a licensed professional engineer, responsible land disturber (RLD), or other knowledgeable person who holds a certificate of competence from the board in the area of project inspection, is enrolled in the board s training program for project inspection or combined administrator, and successfully completes such program within one year of enrollment. Contractor inspections shall be conducted as follows: Either (1) at least once every 14 calendar days and within 48 hours following any runoff producing storm event OR (2) at least every 7 calendar days. Where areas have been finally or temporarily stabilized or runoff is unlikely due to winter conditions (e.g., the site is covered with snow or ice, or frozen ground exists) such inspections shall be conducted at least once every month. Inspections must include all areas of the site disturbed by construction activity, off-site areas (covered by the permit), and areas used for storage of materials that are exposed to precipitation. Inspectors must look for evidence of, or the potential for, pollutants entering a stormwater conveyance system. Control measures identified in the SWPPP shall be inspected for proper installation, maintenance, and operation. Discharge locations, where accessible, shall be inspected to ascertain whether control measures are effective in minimizing impacts to receiving waters. Where discharge locations are inaccessible, nearby downstream locations shall be inspected to the extent that such inspections are practicable. Locations where vehicles enter or exit the site shall be inspected for evidence of off-site sediment tracking. Poindexter Street Streetscape Improvements Phases 3 & 4 June 17, 2009 Stormwater Pollution Prevention Plan Page 13

16 Utility line installation, pipeline construction, and other examples of long, narrow, linear construction activities may limit the access of inspection personnel to the areas described above. Inspection of these areas could require that vehicles compromise temporarily or even permanently stabilized areas, cause additional disturbance of soils, and increase the potential for erosion. In these circumstances, controls must be inspected on the same frequency as other construction projects, but representative inspections may be performed. For representative inspections personnel must inspect controls along the construction site for 0.25 miles above and below each access point where a roadway, undisturbed right-ofway or other similar feature intersects the construction site and allows access to the areas described above. The conditions of the controls along each inspected 0.25 mile segment may be considered as representative of the condition of controls along that reach extending from the end of the 0.25 mile segment to either the end of the next 0.25 mile segment, or to the end of the project, whichever occurs first. Inspection locations must be listed in the report (form is located in Appendix C). Major observations should include: the location(s) of discharges of sediment or other pollutants from the site; amount of rainfall at the construction site since the previous inspection; weather information and a description of any discharges occurring at the time of inspection; location(s) of control measures that need to be maintained; location(s) of control measures that failed to operate as designed or proved inadequate for a particular location; and location(s) where additional control measures are needed that did not exist at the time of inspection. Contractor shall prepare a report summarizing the scope of the inspection, names and qualifications of personnel making the inspection, the dates of the inspection, major observations relating to the implementation of the SWPPP, and actions taken in accordance with Stormwater Regulations. The report shall be made and retained as part of the SWPPP. Inspection reports shall identify any incidents of noncompliance and corrective action required. Where a report does not identify any incidents of noncompliance, the report shall contain a certification that the facility is in compliance with the stormwater pollution prevention plan and this permit. The report shall be signed in accordance with the permit. Copies of the report forms to be completed by the inspector are attached in Appendix C. The inspection reports will be signed in accordance with the permit requirements. These reports will be provided to the operator who will retain these documents as part of the SWPPP for at least three years from the date that permit coverage expires or is terminated. c. Non-stormwater discharges No non-stormwater discharges are anticipated from this project, other than possible discharges from dewatering. If dewatering activities occur, necessary precautions should be taken to insure the safety of all construction workers, due to elevated levels of petroleum which may exist in the on-site groundwater. In addition, appropriate sediment reduction devices and VPDES requirements for groundwater sampling should be employed during dewatering. Contractor is authorized to discharge the following non-stormwaters, if necessary: Discharges from fire fighting activities Fire hydrant flushing Poindexter Street Streetscape Improvements Phases 3 & 4 June 17, 2009 Stormwater Pollution Prevention Plan Page 14

17 Waters used to wash vehicles where detergents are not used Water used to control dust Potable water sources including waterline flushing Routine external building wash down which does not use detergents Pavement wash waters where spills or leaks of toxic or hazardous materials have not occurred (unless all spilled materials has been removed) and where detergents are not used Uncontaminated air conditioning or compressor condensate Uncontaminated groundwater or spring water Foundation or footing drains where flows are not contaminated with process materials such as solvents Uncontaminated excavation dewatering Landscape irrigation Water for dust control, waterline flushing, and others listed above may constitute a nonstormwater discharge from the site during the construction period. All downstream sedimentation and erosion controls will be in place prior to any non-stormwater discharges. These discharges will be directed to areas that are stabilized to minimize erosion. Except as described above, discharges of material other than stormwater must be in compliance with a VPDES permit (other than the stormwater discharge permits referenced herein) issued for the discharge.
