f f F. Q water body or water supply Orel . (h) A comparison, on a per-acre basis , the total nutrient loading from the proposed project.. with the loading rate which would be expected to produce critical eutrophic levels in a water body ( .02 mg/litre total- phosphorus in-- fresh water bodies, .75 mg/litre total nitrogen in salt water bodies) or, in the case of a water supply, the load- ing rate which would produoe nitrate-nitrogen levels in ex- cess of five parts per million. Where the per-acre loading rate from the proposed project will equal or exceed the critical loading a when combined with existing and potential devel opr en t within the recharge area of the water body or water supply well , the- Report shall specify measures tc reduce nutrient loading such as sewage treat- ment, reduction of development density, elimination or re� duct i on of lawn areas, and- 6,5,3 No Definitive Subdivision Plan or Special Permit subject to the provisions of Section 6.5 may be approved by, the Planning Board, unless it has determined, after reviewing the Water Quality Report and any -.ommenILs from the Board of Health , that the pro- posed pro'ec z i., i l l not have a significant adverse affect on public eat :. or safety, aquaeic Fre etatiale resources, any f1sh- eries or sinellfish beds or other wildlife due to ha.ardous or toxic materials, roadway drainage or sedimentation or excessive nutrient levels.
