Papakating Creek Watershed: (NJDEP,2004) The determination of required load reduction for the Papakating Creek watershed ex- cluding the Clove Acres Lake watershed was calculated, considering the load reduction that will occur from implementation of the Clove Acres Lake watershed TMDL. 38 Table 2.

The NJPDES permit for Lounsberry Hollow Middle School identifies the phosphorus limit to be 0.5 mg/l. The future allocation assigned to Lounsberry Hollow Middle School at the full permitted flow was calculated to be an annual load of 22.09 kg/yr of phosphorus. The permit for Leg- ends Resort and Country Club (NJ0023949) allows for a permitted flow of 0.35 MGD, with a final phosphorus concentration of 0.211 mg/l, effective in June 2008. The future allocation for this facility at the TP permit limit of 0.211 mg/l and the permitted flow of 0.35 MGD is 42.18 kg/yr. No additional phosphorus reductions are directed as a result of WLAs 39 Table 3 TMDL calculations for the Black Creek Watershed (Black Creek at Vernon) Current Load Load Capacity % reduc- tion kg TP/yr (lbs/yr) kg TP/yr (lbs/yr) % of LC Load distribution Load allocation Point Sources other than Stormwater* Lounsberry Hollow MS 4.85 (10.67) 22.09 (48.59) 1.2 0 Legends Golf Discharge 7.71 (16.96) 42.18 (92.79) 2.3 0 Nonpoint and Stormwater Sources medium / high density residential 459.5 (1010) 229.45 (504.79) 12.8 50 low density / rural residential 419.4 (922.7) 209.44 (460.76) 11.7 50 Commercial 199.4 (438.7) 99.58 (219.07) 5.5 50 Industrial 26.80 (58.96) 13.38 (29.43) .7 50 mixed urban / other urban 393.1 (864.9) 196.31 (431.88) 10.9 50 Agricultural 851 (1872) 425.48 (934.89) 23.7 50 forest, wetland, water 472.0 (1038) 472.0 (1038.4) 26.3 0 barren land 22.1 (48.7) 22.1 (48.7) 1.2 0 Margin of Safety n/a 74.5 (163.9) 4.2 n/a Total: 2856 (6283) 1807 (3975) 100 37.2 * Notes: (1) From the NJPDES Permit NJ0023949, Legends Resort and Country Club, the current effluent limit for phosphorus is 1.0 mg/l. After 4/1/2008 the monthly average concentration will be 0.211 mg/l. (2) Discharge from Legends Resort and Country Club (NJ0023949) to the Black Creek is allowed from November through March. New Jersey part of Wawayanda/Pochuck River Watershed Site # 01368900 (NJDEP,2005) In the Wawayanda Creek watershed, the load allocations and associated percent reductions for the New Jersey portion of the watershed are shown in the tables below. For the New York por- tion of the watershed, the load is given as a loading capacity on an annual basis (kg TP/yr). The assignment of load reductions to point and nonpoint sources, as well as any further refinements to the load estimates from New York, will be undertaken by the State of New York in the future. However, regardless of the allocation of load within New York, New York is ultimately respon- sible for assuring that the New Jersey SWQS criteria of 0.1 mg/l of total phosphorus is met at the state boundary. 40 Table 4 TMDL calculations for the New Jersey part of Wawayanda/Pochuck River Water- shed Site # 01368900 Current Load * Loading capacity ** % re- kg TP/yr duction kg TP/yr % of LC Total Loadings 9,757 (21465.4) 47 5,170.3 na (11374.66) Load from New York State 7,873 (17320.6) **** 3,898.6 na (8576.92) Nonpoint and Stormwater Sources from New Jersey part of watershed High density residential *** 148.7 (327.14) 71 43.4 (95.48) 3.4 Low density / rural residen- 371.5 (817.3) 71 108.4 8.5 tial*** (238.48) Commer- 126.1 (277.42) 71 36.8 (80.96) 2.9 cial/industrial/transportation*** Deciduous Forest*** 158 (347.6) 0 158 (347.6) 12.4 Emergent herbaceous wet- 4 (8.8) 0 4 (8.8) 0.3 lands*** Evergreen forest*** 62 (136.4) 0 62 (136.4) 4.9 Mixed forest*** 321 (706.2) 0 321 (706.2) 25.3 Open water*** 50 (110) 0 50 (110) 3.9 Pasture/hey*** 484.1 (1065.02) 71 141.3 11.1 (310.86) Row crops*** 113.3 (249.26) 71 33.1 (72.82) 2.6 mixed urban / other urban*** 14.3 31.46) 71 4.2 (9.24) 0.3 Woody wetlands*** 30 (66) 0 30 (66) 2.4 barren land*** 0.3 (.66) 0 0.3 (.66) 0.0 Margin of Safety*** na na 279 (613.8) 22 TOTAL 1,883 (4142.6) 32.5 1271.7 100 (2797.74) Notes: * Current Loadings were calculated using Unit Aerial Loadings (UAL), see Table 9. ** Percent reductions shown for individual sources are necessary to achieve overall reductions calculated from FIRE method. *** Loadings associated with each land use are for a New Jersey part of the watershed excluding loadings from the New York state part of the watershed). ****Load allocated to NY is the allocable load less the New Jersey reductions based on FIRE and applied to unit area loadings 41 Additional Measures Each impaired watershed was assessed for the applicability of a mandatory low phosphorous fer- tilizer ordinance to aid in the reduction of phosphorus loading from nonpoint sources. In the Black Creek and Wawayanda Creek Watersheds, it was determined that the low phospho- rus fertilizer ordinance was required.
