_ • tr <br /> (c) Whether or not the development will cause any direct runoff <br /> _ of roadway drainage, or runoff of sediment due to erosion, <br /> into any surface water body, watercourse or wetland and if <br /> it will adversely affect any fishery, shellfish bed or.,-. - <br /> other wildlife or aquatic vegetative resources. <br /> (d) A determination of the levels, in total pounds and in <br /> } pounds-per-acre, of nitrogen and phosphorus which will be <br /> generated by the development, In making such deter mina <br /> na- <br /> Lion, the following standards shall be used unless the {�4 <br /> applicant demonstrates to the satisfaction of the .hoard <br /> that other standards are applicable. <br /> 1 . Loading per person: 5 l bs. nitrogen per person per <br /> year; .2 lbs, phosphorus per person per Year. Persons ' <br /> r dwe l L i r unit - _ _._ <br /> 2. Loading from lawn fertilizer: 3 l bs* nitrogen per 1000 <br /> square feet per year (with a minimum of 15 l b . per lot ;. <br /> in a single-family subdivision) , . 17 lbs. phosphorous <br /> per 1000 square feet per year with a minimum of .85 <br /> lbs, per lot in a single-family subdivision). <br /> 3. Loading from road runoff: .38 l bs. nitrogen per road <br /> mile per day; .12 l bs. phosphorus per road mile per <br /> day, <br /> (e) The existing condition of the receiving water body, or <br /> water supply (existing or proposed) , including physical <br /> characteristics and water chemistry. easuTement of exist- <br /> ing water quality must be adjusted for summer (peak popula- <br /> tion) conditions. Measurements shall specifically include <br /> concentrations of total phosphorus in fresh water bodies <br /> and total nitrogen in salt ,water bodies. <br /> (f) The expected change in the condition of the water body o <br /> water supply as a result of the proposed development. <br /> (g) The comparison, on a total pounds and a pounds-per-acre <br /> basis, of the total nutrient loading from the proposed <br /> development with the existing. and potential loading from <br /> all other developments and acreage within the recharge area <br /> f any receiving water body or water supply well . <br /> (h) A comparison, on a per-acre basis, of the total nutrient <br /> loading from the proposed project with the loading gate <br /> which would be expected to produce critical eutrophik <br /> levels in a water body .o mg/litre total -phosphorus in <br /> fresh water bodies, .75 mg/litre total nitrogen, in salt _. <br /> water bodies or, in the case of a water supply,- the load- <br /> ing rate which would produce nitrate-nitrogen levels in e � <br />
