Executive Summary

The Wyoming Valley Sanitary Authority (WVSA) has expanded their purpose and powers to include stormwater management. This plan represents a regional effort by WVSA to meet the Pennsylvania Department of Environmental Protection (PADEP) Municipal Separate Storm Sewer (MS4) permitting requirements for the 32 member municipalities located within the Authority’s service area. Permitting requirements intended to be covered by this plan include Pollutant Reduction Plans (PRPs) for stormwater discharges to local surface waters impaired for nutrients and/or sediment and Chesapeake Bay Pollutant Reduction Plans (CBPRPs) for stormwater discharges to surface waters located within the Chesapeake Bay watershed.

The impaired waters and pollutants of concern for each WVSA municipality were determined by referencing the PADEP’s Pollutant Aggregation Suggestions for MS4 Requirements Table (Municipal)1. The WVSA service area contains six impaired waters; five with siltation impairments and one with nutrient impairments. GIS software was used to map stream impairments and determine the planning area associated with each impaired waterway. The Simplified Method was used to calculate the existing pollutant loading for the entire WVSA service area (CBPRP Planning Area) as well as for each impaired water (PRP Planning Areas). The permit-required pollutant load reductions are based upon impairments. For waters with only siltation (TSS) impairments, a 10-percent reduction of sediment pollutant load is required. For waters with nutrient (organic enrichment/low dissolved oxygen) impairments, a 5-percent total phosphorus (TP) reduction is required. The existing pollutant loads and corresponding required pollutant load reduction requirements for each planning area are summarized below. The existing pollutant loads take into account several baseline load reductions for recently-installed BMPs.

In addition to meeting the PRP requirements for impaired waters, the WVSA service area discharges stormwater to surface waters located within the Chesapeake Bay watershed and is therefore required to reduce the TSS loading from their entire service area (Chesapeake Bay planning area) by 10-percent.

As a regional plan, this document will address both the PRP requirements, pollutant reductions required for individual impaired waters, as well as the Chesapeake Bay impairments. The individual impaired water planning areas are included within the larger CBPRP planning area, therefore any pollutant load reductions achieved within the PRP planning areas will also be counted and progress towards achieving the overall CBPRP pollutant load reduction goals.

The BMP implementation strategy developed in order to meet the pollutant load reduction goals includes one regionally-applied project to meet the majority of the Chesapeake Bay sediment load reduction requirement, multiple stream restoration projects to target areas of major erosion along impaired waters, and various small-scale BMP projects to be complete on a local level. The components of the BMP strategy and a summary of the estimated pollutant load reductions associated with each BMP type are shown below.

In order to finance the BMP implementation to achieve the pollutant load reduction goals, WVSA conducted a feasibility study to determine if a regional stormwater authority was in the long term best interest of the Authority, its municipalities, and the community. Stormwater management costs have been historically funded through general tax revenue, however for many municipalities within the WVSA service area, tax revenue remains relatively stagnant and is in demand for other government services. By utilizing a regional stormwater authority through a rate structure, WVSA will bring valuable benefits to the community, including a predictable and dedicated revenue stream to meet growing stormwater management costs and a more equitable distribution of costs among property owners served.

Public participation was integrated into the development of this plan through providing the public with a draft copy of the CBPRP for review and presenting the contents of the CBPRP at a public meeting. During the public meeting, held on August 10, 2017, the information contained in this report was presented and the public was provided an opportunity to ask questions and make comments. A notice was placed in the Wilkes-Barres Citizen’s Voice on August 1, 2017 that briefly described the plan, listed the dates and locations at which the plan was available for review by the public, and the length of time provided for the receipt of comments. Public comments will be reviewed and incorporated into the final version of this plan.

Introduction

As authorized by Pennsylvania Act 68 of 2013, the Wyoming Valley Sanitary Authority (WVSA) expanded their purpose and powers to include stormwater management in 2017. This Chesapeake Bay Pollutant Reduction Plan (CBPRP) represents a regional effort by WVSA to meet a component of the Pennsylvania Department of Environmental Protection (PADEP) Municipal Separate Storm Sewer (MS4) permitting requirements. More specifically, the permitting requirements covered by this plan include Pollutant Reduction Plans (PRPs) for stormwater discharges to local surface waters impaired for nutrients and/or sediment, and Chesapeake Bay Pollutant Reduction Plans (CBPRPs) for stormwater discharges to surface waters located within the Chesapeake Bay watershed. As a regional plan, this CBPRP addresses both the local impairment PRP and CBPRP requirements.

This document was prepared following the guidance provided in the Pennsylvania Department of Environmental Protection (DEP) document 3800-PM-BCW0100k - National Pollutant Discharges Elimination Systems (NPDES) Stormwater Discharges from Small Municipal Separate Storm Sewer Systems Pollutant Reduction Plan (PRP) Instructions2.

The participants include 32 MS4-designated municipalities. A complete list of municipalities participating in the regional plan is included in Appendix I.

Section B: Maps

The WVSA Planning Area Map contains the land uses, impaired streams, and the watersheds (PRP planning areas) associated with each impaired stream located within the WVSA service area (Appendix III). As multiple municipalities are jointly addressing each impaired stream, the PRP planning area shown on the Planning Area Map represents the combined sewershed of all MS4 outfalls discharging to each impaired stream. Due to the large scale of the PRP planning areas spanning several municipalities, the assumption was made that the drainage area to each impaired stream was approximately equal to the HUC-12 watershed. The combined UA from all of the municipalities included within the WVSA service area was used as the CBPRP planning area.

The locations of the proposed BMPs are shown on a separate map by watershed (Appendix III). The Project Location Maps identify the location of each proposed BMP and also include site photos to provide information on the existing conditions of each BMP project site.

The WVSA service area includes 32 municipalities with a total urbanized area (UA) of 47,392 acres according to the 2010 U.S. Census. No areas were parsed from the CBPRP or impaired stream PRP planning areas.

Section C: Pollutants of Concern

The pollutants of concern for each planning area were determined by referencing the PADEP’s Pollutant Aggregation Suggestions for MS4 Requirements Table (Municipal)3. A summary table of the pollutants of concern listed by planning area is below. A full list of the MS4 Municipal Requirements for each municipality within the WVSA service area in included in Appendix IV.

Section D: Determine Existing Loading for Pollutants of Concern

D.1 Existing Pollutant Load Calculation The existing loading in pounds per year for each pollutant of concern was determined for the entire WVSA service area (CBPRP planning area) as well as for each impaired water (PRP planning areas). Existing pollutant loads were calculated using the Simplified Method4. The urbanized area (UA) associated with each planning area was determined using GIS software and the following layers: WVSA Service Area boundary (provided by WVSA); UA boundary (from the 2010 U.S. Census); municipal boundaries (provided by Luzerne County GIS); and the HUC 12 watersheds (USGS National Hydrography data set).

The UA from each planning area was multiplied by the percent pervious and impervious land use values for the corresponding municipality listed in the Statewide MS4 Land Cover Estimates5 to determine the acres of impervious and pervious land within each planning area. The impervious and pervious acreages were then multiplied by the Developed Land Loading Rates for Luzerne County6 to determine the total existing pollutant loading for each planning area (Table 2). As the PRP planning areas are contained within the overall CBPRP planning area, the existing pollutant load was calculated for each PRP planning area as well as the additional portion of the CBPRP planning area not included in a PRP planning area. Therefore, the pollutant load from each of PRP planning areas, plus the pollutant load from the CBPRP planning area not already included in a PRP planning area, is equal to the overall pollutant load for the entire regional planning area.

Table 2. Existing Pollutant Loading by Planning Area UA Existing Pollutant Load (lbs/yr) Planning Area (acres) TSS TP Newport Creek 2,102 1,293,705 -- Warrior Creek/Susquehanna River 3,987 2,243,746 -- Sugar Notch Run/Solomon Creek 4,864 3,698,801 -- City of Wilkes-Barre/Mill Creek 6,325 4,915,349 -- Lackawanna River/Susquehanna River 3,235 2,337,790 -- Harveys Lake/Harveys Creek 1,398 532,121 1,685 CBPRP Planning Area outside of PRP Planning Areas 25,481 19,562,656 -- Total Regional CBPRP Planning Area 47,392 34,584,168 --

A full table of the pollutant loading associated with each municipality within each planning area listed above is included in Appendix V. It should be noted that no areas were parsed from any of the PRP or CBPRP planning areas during the calculation of the baseline pollutant loading, therefore this method provides a conservative estimate of the existing regional pollutant load.

The PRP Instructions allow for removing those areas that do not drain to the MS4 to be removed from the pollutant load calculations7. However, as a new stormwater managing entity, WVSA does not currently have adequate information about the existing MS4 infrastructure to accurately delineate the extent of the areas tributary to the system (i.e. sewershed boundaries). It is anticipated that as WVSA obtains funding and completes mapping of the MS4, this information will be used to refine the regulated sewersheds and the associated baseline pollutant loading in future MS4 Status Reports. D.2 Existing Pollutant Load Adjustment for Previously Implemented BMPs

Two stream restoration projects were completed prior to the completion of this plan and are being utilized as credit to reduce the existing baseline loading estimates for the City of Wilkes-Barre-Mill Creek planning area and the CBPRP planning area (Table 3). Additional information on these BMPs is provided in Appendix V.

Section E: Select BMPs to Achieve the Minimum Required Reductions in Pollutant Loading

E.1 Pollutant Reduction Requirements Six streams within the WVSA service area have water quality impairments required to be addressed as a result of regulation through PAG-13 General Permit, Appendix E (nutrients and/or sediment in stormwater discharges to impaired waterways). Appendix E impairments based on siltation require a minimum 10- percent sediment reduction within the impaired water planning area. Impairments based on nutrients require a 5-percent TP reduction within the impaired water planning area. The pollutant load reduction requirements in pounds per year for Appendix E planning areas are shown in Table 5. The pollutant load reduction requirements listed below take into account adjustments to baseline loading from the installed BMPs listed in Table 3 (Section D.2). More detailed calculations for the pollutant load reduction required for each planning area are included in Appendix VI.

Table 5: Required Pollutant Load Reduction - Impaired Waters Planning Areas Required Load Reduction UA Planning Area Impairment (lbs/yr) (acres) TSS TP Newport Creek 2,102 Sediment 129,371 0 Warrior Creek/Susquehanna River 3,987 Sediment 224,375 0 Sugar Notch Run/Solomon Creek 4,864 Sediment 369,880 0 City of Wilkes-Barre/Mill Creek 6,325 Sediment 489,291 0 Lackawanna River/Susquehanna River 3,235 Sediment 233,779 0 Harveys Lake/Harveys Creek 1,398 Nutrients 0 84

In addition to meeting the PRP requirements for impaired waters listed above, the WVSA service area discharges stormwater to surface water located within the Chesapeake Bay watershed and is, therefore, also regulated by PAG-13 General Permit, Appendix D (nutrients and sediment in stormwater discharges to waters in the Chesapeake Bay watershed). The pollutants of concern for Appendix D are TSS, TP, and total nitrogen (TN) with required loading reductions of 10-percent, 5-percent, and 3-percent, respectively. However, it is presumed that within the overall Bay watershed, the TP and TN goals will be achieved when a 10-percent reduction in sediment is achieved8. Therefore, only the required 10-percent TSS reduction is calculated herein as a requirement for CBPRP planning area load reductions (Table 6).

As discussed in Section D, the planning areas and corresponding pollutant load reduction requirements listed in Table 5 are included within the larger CBPRP planning area. Therefore, any load reduction achieved in one of the PRP planning areas will also count as progress towards meeting the overall CBPRP planning area pollution load reduction goal. As this is a Regional CBPRP, it is presumed that by targeting the placement of BMPs in impaired portions of the planning area watersheds and meeting the overall CBPRP 10% TSS reduction, the nutrient reductions of the impaired watersheds regulated by Appendix E will also be met.

E.2 Proposed BMPs The following section outlines the BMP implementation strategy developed to achieve the required pollutant load reduction goals stated in Section E.1. The proposed BMPs were determined through a review of previously submitted PRPs from municipalities included in the WVSA planning area, in-field stream assessments, conversations with the Luzerne County Conservation District, and public outreach meetings with elected officials and municipal staff. The proposed BMP projects have not been fully designed. The project descriptions are conceptual and intended for planning purposes. Proposed projects have been evaluated in terms of preliminary feasibility and anticipated pollutant load reductions in order to meet the goals of this plan. The proposed BMPs will be designed in accordance with the Pennsylvania BMP Manual design guidance and all local ordinances. Additionally, as many of the proposed projects include stream restoration, all proposed stream restoration projects will be designed in accordance with the requirements listed in DEP’s stream restoration guidance9. Additional details and calculations for each proposed project developed during the design and implementation project phases will be documented in the Annual MS4 Status Reports. A summary of the type and scale of BMP projects included in the WVSA strategy is listed in Table 7. The pollutant loading reductions for the each proposed BMP were calculated in terms of pounds per year using PADEP’s standard BMP Effectiveness Values10. A comprehensive list of the individual BMP projects to be implemented in each planning area is provided in Appendix VI.

The BMP strategy outlined in Table 7 represents the most cost-effective approach to meeting the required pollutant reductions while also improving the quality of local impaired waterways. The proposed BMPs include one large regional BMP to achieve a major sediment load reduction and several smaller local-level BMPs to target specific impaired waters. The pollutant load reductions achieved by the proposed BMPs listed above exceed the pollutant load reduction requirement by 101,734 lbs/TSS/yr. The pollutant load reductions achieved within each PRP Planning area are shown in Table 8. As allowed during the five-year permit term, it is anticipated that the plan will be revised on an annual basis based upon actual progress made and new project opportunities.

E.2.1 Regional BMPs In evaluating potential BMPs, it was determined that the implementation of one large centrally-located BMP, capable of treating a large drainage area, would be more cost-effective than managing, constructing, and maintaining numerous smaller-scale BMPs located throughout the CBPRP planning area. The area proposed for the large BMP, the Toby Creek Impoundment BMP, is shown as BMP-1 on the BMP Location Map (Section B). The proposed regional BMP is an extended detention basin with bioretention plantings located within an existing flood control levee in Pringle Borough. Stormwater from approximately 10,167 upstream acres drains to Toby Creek and is conveyed behind the levee. The existing levee basin is a detention basin meant to collect stormwater and slowly release it at a controlled rate to prevent flooding of downstream areas. While effective for flood control, the basin currently has little impact on water quality. Stabilizing the approximately 2,000 feet of stream that flows through the levee and retrofitting the approximate 7.5 acre footprint of the basin with amended soil for infiltration and water-tolerant plants for sediment and nutrient removal is estimated to remove over three million pounds of TSS per year. Pollutants will be removed when stormwater is filtered through the soil planting bed and vegetation. Additionally, the vegetation in the soil planting bed will provide uptake of pollutants and runoff and help maintain the pores and associated infiltration rates of the soil in the basin. Pollutant Load Reduction calculations for the Regional BMP are included in Appendix VI. Preliminary conversations occurred with the regulators of the levee (U.S. Army Corps of Engineers) and the operators of the levee (Luzerne County Flood Protection Authority) to determine the feasibility of implementing such a large-scale project. The levee system was constructed during the 1950s and raised from its initial height of 37-feet to 41-feet in 2003. The levee system was initially maintained by the municipalities located along each reach of the levee; however, since 1996, the Luzerne County Flood Protection Authority has taken over operation of the levee system and provided consistent maintenance of the levees walls and flood gates. Preliminary discussions indicate that the project opportunity is worthwhile to pursue for this regional plan. Due to the complexity of the system, the proposed amount of sediment reduction credit calculated in this plan, as for all sediment reduction credits, will be evaluated in accordance with DEP guidance as the project is designed and permitted. Regional Chesapeake Bay Pollutant Reduction Plan Wyoming Valley Sanitary Authority, Luzerne County, Pennsylvania Page 14

Stormwater parks, a combination stormwater quality enhancement and recreational space, are included in this plan. The concept is to target locations within the service area with a significant space to work in and a large contributing drainage area that would provide opportunities for rate payers to realize the benefits and aesthetics of stormwater quality BMPs while providing recreational space that improves their quality of life. Specific detail related to the stormwater park concept will be discussed during the implementation of the plan. An allocation for anticipated sediment reduction credit is accounted for in this plan, by assuming each park will treat approximately 20 acres of stormwater runoff. More detailed site-specific calculations will be developed during the project design process. E.2.2 Local BMPs In order to address local impaired waters, site visits were conducted throughout the PRP planning areas to determine sites for potential BMP projects. The areas proposed for local-level stream restoration projects include sections of streambank observed as having severe erosion within the following planning areas: Newport Creek, Warrior Creek-Susquehanna River, Sugar Notch-Solomon Creek, City of Wilkes-Barre- Mill Creek, and Lackawanna River-Susquehanna River. Depending on the severity of the erosion and stream flow at the particular site, stream restoration may include the structural stabilization of streambanks to repair eroded banks and prevent future erosion and/or the installation of in-stream structures to redirect flow and/or absorb water energy. An allocation for local-lead rain garden or small BMP installation is included in this plan as WVSA anticipates providing a cost-share program with this purpose. It was assumed that approximately 25 small- scale local BMPs will be installed throughout the regional CBPRP planning area. To the extent that local rate payers or municipalities look to propose BMPs on their properties, those implemented BMPs will be reported on an annual basis to WVSA as credit toward the regional CBPRP goal. The proposed BMP strategy also includes several BMPs that were proposed by municipalities during previous pollutant planning efforts prior to the involvement of WVSA. These BMPs include a riparian buffer along East Fork Harveys Creek and a tree planting and several small rain gardens in Plains Township. The Harveys Creek riparian buffer will be a permanent area of trees and shrubs located adjacent to the streams. The buffer will be approximately 50-feet wide and provide both ecological and water quality benefits. The Plains Township rain gardens will be excavated and shallow surface depressions planted with specially selected native vegetation to treat and capture runoff. The vegetation serves to both filter and transpire runoff, and the root systems can enhance infiltration. The plants take up pollutants; the soil medium filters out pollutants and allows storage and infiltration of stormwater runoff; and the bed provides additional volume control. Calculations for the anticipated pollutant load reductions associated with these BMPs and the basis for certain assumptions are included in Appendix VI. More detailed pollutant load reduction calculations for these BMPs will be developed according to the prevailing DEP guidance during the design and implementation phase of the project and submitted with the Annual Status Reports.

Regional Chesapeake Bay Pollutant Reduction Plan Wyoming Valley Sanitary Authority, Luzerne County, Pennsylvania Page 15

E.2.3 BMPs to Be Installed by Others The WVSA design strategy may potentially include a project to be completed by another entity. The Luzerne County Conservation District is in the process of planning a stream restoration project in Edwardsville Borough along Toby Creek. If this project is implemented during the permit term, the pollutant load reductions for this stream restoration will be credited towards WVSA’s pollutant load reduction goal. E.3 Partnerships Non-municipal MS4s and industrial permittees were not parsed out of this plan. As a result, stormwater management BMP accomplishments of other NPDES permit holders can also count toward meeting the Regional CBPRP pollutant reduction goals, provided that they meet pollutant reduction plan criteria. E.3.1 Flood Protection Authority Partnership Being that the regional levee system serves a portion of the planning area, it is anticipated that the system may be considered for bioretention retrofits, depending on the success of the Toby Creek Impoundment. To that end, this plan may be revised in the future to include other retrofit opportunities that align with the Flood Protection Authority’s operation and maintenance projects.

E.3.2 PennDOT Partnership This planning strategy does not cite any PennDOT projects as planned projects contributing to the planning goal. However, it is anticipated that WVSA will attempt to engage PennDOT during the implementation of the plan so that joint credit opportunities can be achieved. Further, PennDOT has indicated that there is an intention to coordinate PennDOT projects with local municipalities during the 2018-2023 permit term. PennDOT and the municipality/WVSA will share any reductions achieved through partnership projects, provided the municipality or WVSA either contributes funding or agrees to perform the long-term operation and maintenance responsibilities for the additional or enhanced stormwater controls.

As part of the Annual MS4 Status Reports submitted under this permit, PennDOT will provide a list of actions taken by the department to support municipalities in achieving their PRP goals in Sediment Impaired Watersheds in urbanized areas. E.4 Other Reportable BMPs Notwithstanding that the Regional CBPRP outlines enough planned projects to meet the regional pollutant reduction goal, pollutant reduction planning requirements are also intended to be met through municipal actions and approvals. Examples of BMP reporting opportunities are described below. Any permit-eligible BMP documentation for pollutant reductions will be accepted for inclusion in the Annual MS4 Status Reports.

E.4.1 Stormwater Inlet Cleaning As part of on-going MS4 maintenance, several municipalities within the WVSA service area routinely remove solids from their MS4s. However, at this time, no pollutant reduction has been allotted to storm sewer system solids removal because tracking of this removed material has not been to the degree required to accurately calculate the pollutant load reduction as described in the PADEP BMP effectiveness values Regional Chesapeake Bay Pollutant Reduction Plan Wyoming Valley Sanitary Authority, Luzerne County, Pennsylvania Page 16

table11. It is anticipated that municipalities that track inlet cleaning in accordance with DEP requirements will report those activities to WVSA for inclusion in the Annual MS4 Status Reports. The reported reduction will contribute toward meeting the sediment reduction five (5)-year goal. WVSA’s level of service provided to the participating municipalities may also include inlet cleaning once mapping is completed. When that portion of the maintenance service begins, WVSA will have in-house staff to track this data for inclusion in the Annual MS4 Status Reports. E.4.2 Land Development BMPs Installed On Sites with Less than One Acre of Disturbance To the extent that local municipal ordinances require the installation of stormwater BMPs at construction sites where land disturbance will be less than one-acre, those BMPs can be reported to WVSA for inclusion in the Annual MS4 Status Reports and the reported reductions will contribute toward the sediment reduction five-year goal.

E.4.3 Street Sweeping Municipalities that regularly conduct street sweeping (at least 25 times per year) may use this practice for pollutant load reduction credit as long as street sweeping is conducted in accordance with the minimum standards outlined in the Chesapeake Bay Program expert panel report for street sweeping12 and the guidance provided on the BMP Effectiveness Values Table13 is used to calculate the corresponding pollutant load reduction. The reported reduction will contribute toward meeting the sediment reduction five (5)-year goal. Similar to the level of service discussed in Section E.4.1, should WVSA include street sweeping in the service offerings to the participants, this data will be tracked for inclusion in the Annual MS4 Status Reports and as credit toward the regional pollutant reduction plan goal.

Section F: Identify Funding Mechanisms This BMP implementation strategy outlined in Section E will be implemented by the Wyoming Valley Sanitary Authority (WVSA) as outlined in the Intergovernmental Agreements (“Agreements”) between WVSA and each of the partner municipalities. The WVSA is in the process of expanding their purpose and powers to include stormwater management and via the Agreements will serve in the role of MS4 Permit Administrator for the 2018 permit cycle. As an existing Authority, WVSA has a fee structure in place to provide sanitary sewer service. WVSA intends to enact a similar fee to cover Permit Administrator and plan implementation costs, including BMP construction, operation and maintenance, and other expenditures related to MS4 regulatory compliance.

WVSA is in the process of forming strategic partnerships with entities such as the US Army Corps of Engineers and the Luzerne County Flood Protection Authority in order to reduce costs and will consider government-subsidized grant and loan options for construction projects.

Section G: BMP Operations and Maintenance (O&M) Once implemented, the BMPs outlined in this plan will be operated and maintained by WVSA to ensure that they continue to produce the expected pollutant reductions. The O&M activities will be reported in the Annual MS4 Status Reports submitted in accordance with the General Permit. The general list of the activities involved with O&M for each BMP and the frequency at which O&M activities will occur are as follows: Table 8: O&M Activities by BMP Type

Responsible BMP O&M Activities Frequency Party Mowing 10 times per year Selective Weeding Annually at beginning of growing season Toby Creek WVSA Staff Impoundment Invasive species removal Annually at end of growing season Inspection Monthly (and after large storm events) Sediment Removal As needed in compliance with permit requirements Twice per year and as needed after major storm Inspection events Revegetation (replanting, replacement of dead, or Stream impaired vegetation) As needed WVSA Staff Restoration Repairs to streambank armoring structures As needed Removal of nuisance aquatic vegetation/ woody debris As needed Inspection Twice per year Riparian Watering Regularly during the first growing season WVSA Staff Buffer Mowing/Weed Control Twice per growing season Invasive Removal As needed Inspection Twice per year Annually (or as needed while vegetation is being Pruning/Weeding established) WVSA Cut down Perennial Staff/ Rain Gardens Plantings/ Detritus Municipal Removal Annually (at end of growing season) Partners Every 2 - 3 years Re-spread Mulch (or as needed when erosion is evident) Watering As needed during periods of extended drought

The design and construction specifications of Toby Creek Stream Restoration project was documented in the Toby Creek Streambank Stabilization Project Design Package, prepared by the Luzerne Conservation District for Courtdale Borough, November 2013. This report included the following description of the project.

“The streambank stabilization using riprap rock to effectively stabilize the 200-foot streambank area and prevent further degradation of the waterway. Stabilizing the stream with the proposed riprap lining will eliminate the potential for a much more costly restoration effort if the stream continues to degrade. Also, at both ends of this 200-foot reach of stream are three trees plus a pile of about 40 tires that will need to be removed to access the construction area. All of the disturbed area will need to be seeded/stabilized once construction has been completed.

R8 riprap at a maximum height of nine feet can be used to stabilize the approximate 200 feet of eroding stream bank. The stabilization effort should include a five-foot-long key-in of the R8 riprap at the upper and lower ends of the riprap placement.”

The stream restoration project is located at 41.291565; -75.909539. This location is labeled as EX-1 on the WVSA Planning Area Map. According to the Luzerne Conservation District, the project was permitted by General Permit 114012421 on October 15, 2012. The pollutant load reduction for the stream restoration project was calculated as described in the BMP effectiveness table (length of stream in feet multiplied by the BMP effectiveness value of 44.88 lbs. TSS/ft/yr). According the Luzerne Conservation District, this BMP continues to function as designed. The operation and maintenance (O&M) activities associated with the BMP include the following:  Inspect streambank after storms and observe any displacements of rock or erosion upstream or downstream of the riprap. Repair minor damages.  Be aware of obstruction in the stream, which high water can deposit. Often this form of material is beneficial as aquatic habitat, but located inappropriately it can deflect flows into an unprotected streambank and cause scour. Allow for aquatic habitat, but in situations which are causing damage, rearrange or remove the obstruction. Regional Chesapeake Bay Pollutant Reduction Plan Wyoming Valley Sanitary Authority, Luzerne County, Pennsylvania Page 37

 Encourage natural streambank stability from shrubs growing on the slope of streambank and trees on the top of bank. Laurel Run Stream Restoration

The Laurel Run stream restoration project involved the restoration of 500 linear feet of stream bank along Laurel Run within the municipal boundary of the City of Wilkes-Barre. Grouted rip-rap was installed to restore the streambank that was eroded. An access point was created for future maintenance of the streambank. The stream restoration project is located at latitude/longitude location 41.257283, -75.838397. This location is labeled as EX-2 on the WVSA Planning Area Map. The pollutant load reduction for the stream restoration project was calculated as described in the BMP effectiveness table (length of stream in feet multiplied by the BMP effectiveness value of 44.88 lbs. TSS/ft/yr.). According to the Luzerne Conservation District, this BMP continue to function as designed.

The location of the Toby Creek Impoundment is shown on the Planning Area Map as (BMP-1).

The UA drainage area to the Toby Creek Impoundment includes multiple municipalities, both within and outside of the WVSA planning area. The conceptual design for the proposed basin most closely resembles a wet pond and therefore the BMP effectiveness value15 for this type of BMP (60%) was used to estimate the pollutant load reduction for the Toby Creek Impoundment. As the UA outside of the WVSA planning area is regulated by separate MS4 permits, it was assumed that the stormwater runoff from this drainage area will already have a reduced sediment loading (10% in accordance with the 2018 PAG-13) when it reaches the Toby Creek Impoundment for further treatment.

Therefore, the proposed basin will provide secondary treatment to the stormwater runoff from outside the WVSA planning area and primary treatment for the stormwater runoff from the drainage area within the WVSA regional planning area.
