DOCUMENT AVAILABILITY The proposed TMDL Plan, PRP, and CBPRP are available for review at the Township office located at 315 Clay Road, Lititz, PA 17543 and the Borough office located at 7 S. Broad Street, Lititz, PA 17543 from 8:30am to 4:00pm Monday-Friday beginning July 19, 2017. The proposed TMDL Plan, PRP, and CBPRP are available to view or download at warwicktownship.org or lititzborough.org. SUBMISSION OF COMMENTS The Township and Borough shall jointly accept written comments for a minimum of 30 days from the date of public notice. Interested parties may submit written comments electronically, by mail, or hand delivery.

They also must submit a Total Maximum Daily Load (TMDL) Plan to address the existing sediment TMDL for the Lititz Run Watershed as well as a Chesapeake Bay Pollution Reduction Plan (CBPRP) for the Lititz Run watershed. Manheim Township has partnered with Lititz Borough and Warwick Township on the development and submittal of the TMDL/CBPRP portion of this report. These plans are a requirement of Lititz Borough’s existing Permit PAG#133539, Warwick Township’s existing permit PAG#133565 and Manheim Township’s existing permit PAG#133534 for their MS4. Warwick Township and Lititz Borough previously submitted a TMDL Update Plan dated February 1, 2013 in which it was demonstrated that the 2004 sediment TMDL for the Lititz Run watershed was met based on a comparison of the watershed based 2012 unit area loading rate to the prescribed unit area loading rate in the 2004 TMDL. The 2013 TMDL update built upon the 2004 watershed model and considered land use changes and BMPs implemented after 2004. Although the TMDL has been met there is still an Appendix D Chesapeake Bay load reduction requirement for Lititz Run. The 2017 Lititz Run Watershed TMDL Plan assumes the TMDL has been met as demonstrated in the previously submitted plan. This 2017 Plan provides an update of the site conditions and modeling input in the Lititz Run watershed, and uses the latest version of the MapShed model. Note that due to significant changes in the MapShed model and improved accuracy of agricultural input data (to be discussed later), the reported pollutant loadings cannot be directly compared to the 2004 or 2013 results. The load resulting from Lititz Borough, Warwick Township and Manheim Township Urban Area will be calculated using the urban area tool in MapShed and no parsing will be used to reduce the existing load. Although the TMDL has been met, Warwick Township and Lititz Borough continue to implement BMPs that will improve local water quality, provide community benefits and improve the greater Chesapeake Bay watershed. The BMPs proposed over the next 5 year permit cycle will be described in this report and will meet the Chesapeake Bay Appendix D pollution reduction requirement as well as the IWP Requirement. The IWP, CBPRP and TMDL Plan have been combined into one Pollution Reduction Plan (PRP) document. Planning areas were identified for the Little Conestoga, Conestoga, Hammer and Cocalico Creek watersheds and parsing was used to exclude areas as described later in this report. The load from the identified planning areas was calculated using the simplified method and then normalized to be consistent with the magnitude of loads calculated using the MapShed model. All the loads in Lititz Borough and Warwick Township were then aggregated, as Lititz Run TMDL Plan Warwick Twp. And Lititz Borough Pollution Reduction Plan July 14, 2017 Page 1 discussed with DEP, and BMPs were identified to exceed the 10% reduction requirement of the aggregated load. In summary, this Joint PRP includes public participation documentation, mapping of outfalls and other discharges, pollutant load calculations, best management practices (BMPs) selection, identification of potential funding sources and partners, and operations and maintenance (O&M) activities for Lititz and Warwick Townships and the portion of Manheim Township in the Lititz Run Watershed. A. Public Participation – to be completed following Public Comment Period Public participation is an essential part of the PRP because it enhances buy-in from landowners that may have an impact on pollutant discharges, can uncover missing elements or errors in calculations, and builds cooperative partnerships among the municipality and other entities. A copy of the draft TMDL/IWP was released via public notice on MONTH, DAY, YEAR to the following media outlets: ____________. The notice ran for # days. A copy of the public notice is included in Attachment A. The public was given 30 days to provide commentary on the contents of the PRP. A copy of all written public comments is included in Attachment A. Public meetings were held on the following dates to receive verbal commentary on the contents of

  • Colonial Mill Sediments in Lancaster County
    Southeast Friends of the Pleistocene (SEFOP) Guidebook, Fall 2003 Fieldtrip, 17-19 October 2003 Colonial Mill Ponds of Lancaster County Pennsylvania as a Major Source of Sediment Pollution to the Susquehanna River and Chesapeake Bay Dorothy Merritts and Robert Walter Department of Earth and Environment Franklin and Marshall College Lancaster, PA 17603 [email protected] [email protected] INTRODUCTION The timing and ultimate source of sediment erosion in Lancaster County has far-reaching implications beyond local interests in farmland conservation. The Conestoga watershed is an environmental hotspot, yielding by far more sediment pollution to the Susquehanna River per acre of land than any other part of the Susquehanna River watershed (c.f., Reuter et al., this volume; Gellis, this volume). Sediment is the greatest stream pollutant in the United States, and it is especially devastating to the Chesapeake Bay as a contributor to algal blooms, low oxygen levels, and habitat degradation. Until the 1930s, much of the sediment in Lancaster County streams came directly from farm slopes, as greater than 70% of the County was farmland and farmers had not yet begun to practice conservation techniques such as contour plowing and crop rotation. Since that time, however, many Lancaster County farmers have worked with county, state, and federal agencies to mitigate soil erosion. Still, the amount of sediment pollution from Lancaster County to the Susquehanna has remained high. The critical question is why – why fifty years after the implementation of conservation farming practices is Lancaster County still one of the most significant contributors of sediment to the Susquehanna River and the Chesapeake Bay.
