Sullins Director September 25, 2009 Dee Freeman Secretary Subject: Notification of Jordan Lake Nutrient Requirements NPDES Permit NCO065412 Pleasant Ridge WWTP Rockingham County Governor Bev Perdue recently signed legislation to complete passage of rules for the Jordan Lake Nutrient Management Strategy. The Strategy includes a Wastewater Discharge rule (T15A NCAC 02B .0270) that applies to your wastewater treatment facility. Pursuant to Sub -Item (6)(d) of the rule, I am writing to notify you of the nutrient allocations assigned to your facility. This letter addresses only certain provisions of the Jordan Lake Wastewater Discharge rule. I encourage you to familiarize yourself with the remainder of this rule. Nutrient Allocations. The Wastewater Discharge rule establishes the maximum loads of nitrogen and phosphorus that can be released from wastewater treatment facilities into the Jordan Lake watershed. The rule provides that these wasteload allocations are to be divided among the existing facilities in proportion to (with specific exceptions) their 2001 permitted flows. It also provides that facilities permitted to discharge 100,000 gpd or more are to receive nitrogen and phosphorus limits equivalent to their individual allocations. Your facility has been assigned nitrogen and phosphorus allocations. The allocations are expressed as annual mass loadings delivered to the lake. Due to foreseeable losses between the discharge point and the lake, they are also expressed as the equivalent discharge loads at the point of discharge. The delivered and the corresponding discharge allocations assigned to your facility are as follows: NC0065412 Delivered Allocation (lb/yr) Transport Factor (%) Discharge Allocation (lb/yr) Total Nitrogen 438 51 858 Total Phosphorus 64 45 143 2001 Permitted Flow: 0.0235 MGD 1617 Mail Service Center, Raleigh, North Carolina 27699-1617 Location: 512 N. Salisbury St. Raleigh, North Carolina 27604 Phone: 919-807-63001 FAX: 919-807-64921 Customer Service: 1-877-623-6748 Internet: www.ncwaterquality.org An Equal Opportunity l Affirmative Action Employer NorthCarolina AdAmallr, Sam Misuraca Notification of Jordan Lake Nutrient Requirements September 25, 2009 Nutrient Limits. Your facility will not receive new nutrient limits at this time. However, any nutrient limits already in your NPDES permit will remain in effect. If the facilities permitted for less than 100,000 gpd, as a group, approach their allocations for nitrogen or phosphorus, the Division will consider whether nutrient limits are necessary to protect water quality at that time. In the event that nutrient limits become necessary, the limits would equal your facility's discharge allocations. Nutrient Trading. The rule provides that, when one utility connects to another, the allocations held by the closing facility are transferred to the remaining facility. The rule also provides for the trading of allocations among dischargers within each of the major Jordan subwatersheds. Be sure to consult with the Division's NPDES staff before you consider selling allocation: transactions can have profound implications for your facility and its permit. If you have any questions regarding these allocations, please contact me at (919) 807-6402 or at mike. templeton@ncdenr.gov. cc: Winston-Salem Regional Office NDPES Files Central Files Sincerely, �tc Coleen H.
