APPENDIX IBEST MANAGEMENT PRACTICESBest Management Practices listed in the Plum Creek Watershed Protection Plan to beimplemented.Urban Stormwater MeasuresCommon Goals• Implement non-structural components of MS4 permits on a voluntary basis inadvance of program requirements• Conduct stormwater engineering analyses and city-wide assessments to determineplacement of structural management measures in individual cities• Pet waste management, including passage or modification of ordinances andinstallation and management of pet waste stationsLockhart• Enact a pet waste ordinance• Install 10 pet waste stations and signage• Nutrient/irrigation water management in park areas• Manage/periodically relocate duck population at City Park• Continue/expand existing street sweeping programLuling• Reconstruct Cottonwood Creek stormwater retention pond• Enact a pet waste ordinance• Install 6 pet waste stations and signage• Continue/expand existing street sweeping programWastewater Management MeasuresWastewater Treatment Facilities• Promote signing of the East Hays County Wastewater Compact, a key interlocalagreement between multiple entities in the region.• All WWTFs agree to work toward treatment levels of 5-5-2-1(BOD/TSS/NH 3 /TP) by way of permits for new facilities and voluntary action byexisting plants.• All WWTFs will begin monthly self-monitoring of effluent for bacteria andnutrients.• All WWTF operators will demonstrate the appropriate licenses and certificationsand be current on continuing education opportunities.
APPENDIX I• The cities of Kyle, Lockhart, and Luling will evaluate costs and feasibility in aneffort to implement phosphorous removal techniques for all effluent enteringPlum Creek.Wastewater Infrastructure• Cities will continue or initiate daily inspections of lift stations and equip allstations with dialers and/or Supervisory Control and Data Acquisition (SCADA)systems.• Cities will continue to apply for grants to replace old clay pipe sewer lines, andclean and maintain existing sewer lines.• Cities will work to locate any septic systems that may still be within the citylimits and connect those residences to central wastewater treatment.Cropland Operations Management MeasuresTo focus management plan development and implementation, management measures,addressing bacteria and nutrient issues will be encouraged and given top priority. Basedon site-specific characteristics, plans should include one or more of the followingmanagement practices to reduce pollutant loads from agricultural lands:• Prescribed Grazing: Manages the controlled harvest of vegetation with grazinganimals to improve or maintain the desired species composition and vigor of plantcommunities, which improves surface and subsurface water quality and quantity.• Riparian Herbaceous Buffers: Establishes an area of grasses, glasslike plants, andforbs along water courses to improve and protect water quality by reducingsediment and other pollutants in runoff as well as nutrients and chemicals inshallow groundwater.• Grasses Waterways: Natural or constructed channel-shaped or graded andestablished with suitable vegetation to protect and improve water quality.• Riparian Forest Buffers: Establishes area dominated by trees and shrubs locatedadjacent to and up-gradient from watercourses to reduce excess amounts ofsediment, organic material, nutrients, and pesticides in surface runoff and excessnutrients and other chemicals in shallow groundwater flow.• Watering Facilities: Places a device (tank, trough, or other watertight container)that provides animal access to water and protects streams, ponds, and watersupplies from contamination through alternative access to water.• Field Borders: Establishes a strip of permanent vegetation at the edge or aroundthe perimeter of a field to protect soil and water quality.
