3 LAKE HOPATCONG 1800 S Tourist Destination Boating and Recreation

4 MAJOR USES Boating Fishing Swimming Sight seeing Intense recreational use 35,000 boats Water Supply State Park acres 500,000 annual visitors

5 Like many lakes in the nation, shoreline is no longer predominately seasonal bungalows.

6 USE IMPAIRMENTS Woodport Area

7 OUTLINE History 314 studies and LHRPB TMDL Refined TMDL (as called for in TMDL) Components of TMDL (wastewater, s.w.) How we address each Additional measures to achieve Additional issues (land use) Where we are now

8 LAKE HOPATCONG REGIONAL PLANNING BOARD Began 1964 Lack of Authority Lack of Funding Disbanded upon creation of Lake Hopatcong Commission Some data available for 20 years, fairly consistent, funded through EPA Clean Lakes Studies and other sources.

9 LAKE HOPATCONG COMMISSION Created by Legislature in 2000 First Lake Hopatcong Meeting - May 2001 Mandate: To oversee and safeguard Lake Hopatcong as a natural, scenic and recreational resource. 11 Members 5 State/6 Local State - Chair, DEP & DCA Commissioners and 2 Public Members Local - Morris & Sussex County, Borough of Hopatcong, Jefferson Township, Roxbury Township; Borough of Mt. Arlington

16 IMPLEMENTATION WHO?

17 USEPA USEPA Wetlands Grant The Lake Hopatcong Commission received a grant from EPA to identify and map critical wetlands surrounding Lake Hopatcong.

18 MAJOR SOURCES Wastewater Management 52% Failing Septic Systems Stormwater runoff 31% High density land uses

19 WASTEWATER MANAGEMENT Plan to consolidate into Regional Treatment Plant Roxbury sewered 100% Mt. Arlington sewered 100% Hopatcong is in the process of sewering Phase I complete (1811 EDUs) Phase II underway Plan is to sewer 15,171 residents. Jefferson has no near term plans to sewer

20 HOPATCONG SEWER PROJECT First 2 Phases nearing completion Total of 14 construction contracts 2850 customers to be served Collection system utilizes gravity sewers and low pressure sewers 925 grinder pumps 4 neighborhood pump stations 564, 822 feet or 107 miles of pipe Courtesy Hach Mott Macdonald

30 STORMWATER MANAGEMENT 319(h) funded implementation- 4 projects $844,500 EPA Targeted Watershed Initiative Grant $745,000 NJDEP adopted 2 Stormwater Rules in Feb to address existing stormwater issues (Phase II) and to address future development (Stormwater management). Phase II rules include requirements for ordinances for not feeding waterfowl, picking up pet waste, illicit connection trackdown and education. Stormwater Management Rules include requirements for Municipal Plans that must look at TMDLs; 300 ft buffers for Category-1 waters; BMP technical manual and performance standards for recharge, quantity and quality.

37 ADDITIONAL MEASURES Stormwater and Wastewater are identified as the two major contributors. Reduction of sources through additional measures to reduce the phosphorus load, whether external loading or internal will also help to achieve the TMDL.

42 Estimated TP removal from harvesting Total Phosphorus (lbs) removed through weed harvesting TP (lbs) Year

43 COLLECTED MACROPHYTE SAMPLES FOR TP ANALYSIS First set of samples collected on 17-Jul-06. Three samples of EWM*, three of tapegrass, two of Lyngbya, four community samples, and four additional samples of other plant species. Second set collected on 28-Sep-06. Three samples of EWM, two of tapegrass, three of Lyngbya, four community samples, and three additional samples of other plant species. *EWM=Eurasian Water Milfoil Courtesy Dr. Fred Lubnow, Princeton Hydro, LLC

44 Results July 2006 EWM TP varied 1,650 and 2,400 mg/kg (mean of 2,137 mg/kg) Tapegrass TP varied 1,340 and 2,900 mg/kg (mean 2,030 mg/kg) Lyngbya TP varied 1,220 and 2,340 mg/kg (mean 1,780 mg/kg) Community TP 1,680 and 3,930 mg/kg (mean of 2,693 mg/kg) Sept EWM TP varied 1,200 and 1,710 mg/kg (mean 1,513 mg/kg) Tapegrass TP varied 550 and 1,210 mg/kg (mean 880 mg/kg) Lyngbya TP varied 1,430 and 2,400 mg/kg (mean 1,970 mg/kg) Community TP 1,140 and 3,240 mg/kg (mean 1,878 mg/kg) Courtesy Dr. Fred Lubnow, Princeton Hydro, LLC

45 Results 2006 Using a mean 2006 community-based TP concentration of 2,285 mg/kg and the 2006 removed harvested biomass of 1,290.6 tons, it was estimated that 209 kg of TP was removed. Approximately 6.3% of the TP load targeted for reduction under the TMDL Using a mean 2006 community-based TP concentration of 2,285 mg/kg and the 2007 removed harvested biomass of 1,600 tons, it was estimated that 259 kg was removed. This accounts for approximately 7.8% of the TP load targeted for reduction under the TMDL. Courtesy Dr. Fred Lubnow, Princeton Hydro, LLC

46 P-FREE FERTILIZER

47 Liquid or granular lawn fertilizer must have 0.5% of phosphorus of less Must be applied when ground is not frozen Fertilizer applications can not be made within 10 feet of any wetland, stream, or waterbody No person shall deposit leaves or other vegetative materials on roads or within any lake, pond, stream or stormwater drainage system.

58 IMPLEMENTING A TMDL AS A WATERSHED EFFORT IS NOT: FAST EASY WITHOUT PROBLEMS WITHOUT FRUSTRATION AND AGGRAVATION ONE STRAIGHT SHOT A SOLO ENDEAVOR CHEAP A 30-SECOND SOUND BITE STATIC

59 IMPLEMENTING A TMDL AS A WATERSHED EFFORT IS: REWARDING ENGAGING ENRICHING CUMULATIVE AN EXPERIENCE OF THE WHOLE IS GREATER THAN THE SUM OF THE PARTS HUMBLING AN AMAZING LEARNING JOURNEY THE ONLY GAME IN TOWN
