WR2.1 Five ppm Nitrogen Loading Standard. The maximum nitrogen loading standard <br /> for impact on groundwater shall be 5 ppm for development and redevelopment unless a <br /> cumulative impact analysis indicates a more stringent loading standard is necessary. <br /> In addition to the above standards WR2.1 to WR2.4,for areas mapped as Potential Public Water <br /> Supply Areas, the following minimum performance standards shall apply. The Conunission may <br /> determine that WR2.5 and WR2.6 do not apply provided that supporting information from the <br /> Town or Water District demonstrates to the Commission that the area Will not be considered as <br /> potential water supply areas. <br /> WR2.6 One ppm Nitrogen Loading Standard. The maximum nitrogen loading standard <br /> for impact on groundivater shall be 1 ppm for development. Guidance on methodology to <br /> meet this standard can be found in Cape Cod Commission Nitrogen Loading Technical <br /> Bulletin 91-001, as amended. <br /> 4.0 FERTILIZER MANAGEMENT STRATEGIES USED IN OTHER LOCALES <br /> HW conducted a review of fertilizer management strategies used by municipalities across the <br /> country that may be applicable for use in the Pleasant Bay watershed. These were obtained from <br /> an internet search based on the following keywords: <br /> • Florida friendly landscaping; <br /> • Florida friendly fertilizer; <br /> • WaterStar; <br /> • Greenscapes; <br /> • Seattle greenscapes; <br /> • Fertilizer campaign; <br /> • Maine phosphorus manual; <br /> • Fertilizer moratorium; <br /> • Fertilizer/nutrient limit; <br /> • Lawn removal; <br /> • Lawn replacement; <br /> • Buffer for fertilizer/nutrient management; <br /> • Best management practices (BMPs) for fertilizer attenuation; and <br /> • Golf course fertilizer management. <br /> HW identified a series of programs and evaluated their applicability within the Pleasant Bay <br /> watershed towns. For example, other states such as Florida or Washington may have different <br /> soils and growing seasons from the Pleasant Bay watershed,but their fertilizer management <br /> strategies may still be adapted to Cape Cod conditions. <br /> Sixteen programs are described below, divided into regulatory programs and standards, non- <br /> regulatory programs, and BMPs for fertilizer applications.
