NOTE: Sample supply calculation for a ten-acre site located within the Bickel's Run subbasin: |
Bickel's Run is designated a high-quality, special protected waters by PA DEP. Bickel's Run is a first-order stream as shown in Figure 9-4. Therefore, the water budget impact standard, per Table 9-4, would require maintenance of 75% of Q7-10 flow by applying a multiplier of 0.25. Q7-10 flow for the site would be 143GPD/acre, using Figure 9-5. | |||
Supply | = | impact standard multiplier x site acreage x site Q7-10 flow | |
Supply | = | 0.25 x 10 acres x 143 GPD/ac | |
