PROPOSED

PUBLIC NOTICE

Proposed Total Maximum Daily Loads (TMDLs) for the Chesapeake Bay Drainage Basin (Chester River, Choptank River, Marshyhope Creek, Nanticoke River, Gum Branch, Gravelly Branch, Deep Creek, Broad Creek, and Pocomoke River Watersheds), the Inland Bays Drainage Basin (Buntings Branch, Little Assawoman Bay, Assawoman Bay, Indian River Bay, Iron Branch, Indian River, Rehoboth Bay, and Lewes-Rehoboth Canal Watersheds), and the Murderkill River and Appoquinimink River Watersheds, Delaware

Brief Synopsis of the Subject, Substance, and Issues

The Department of Natural Resources and Environmental Control (DNREC) plans to conduct two Public Workshops to review draft Total Maximum Daily Loads (TMDLs) Regulations for bacteria for the Chesapeake Bay Drainage Basin (Chester River, Choptank River, Marshyhope Creek, Nanticoke River, Gum Branch, Gravelly Branch, Deep Creek, Broad Creek, and Pocomoke River Watersheds), the Inland Bays Drainage Basin (Buntings Branch, Little Assawoman Bay, Assawoman Bay, Indian River Bay, Iron Branch, Indian River, Rehoboth Bay, and Lewes-Rehoboth Canal Watersheds), and the Murderkill River and Appoquinimink River Watersheds. A TMDL sets a limit on the amount of a pollutant that can be discharged into a waterbody and still meet water quality standards. TMDLs are composed of Waste Load Allocations (WLAs) for point source discharges, Load Allocations (LAs) for nonpoint sources, and a Margin of Safety (MOS) to account for uncertainties.

The proposed Bacteria TMDL Regulations for the Chester River, Choptank River, Marshyhope Creek, and Pocomoke River Watersheds are necessary because the existing TMDL regulations that included both nutrient and bacteria allocations, promulgated on January 11, 2006 are being modified to include nutrients only. This change is required due to a clarification in the interpretation of the EPA-required, bacteria water quality standards that result in changes to the bacteria allocations.

Possible Terms of the Agency Action

Following the Public Workshops and after reviewing comments received during the comment period, Public Hearings will be scheduled to adopt the proposed Total Maximum Daily Loads for these Watersheds. Following adoption of the TMDL Regulations, DNREC will develop Pollution Control Strategies (PCSs) designed to achieve the necessary load reductions. PCSs will identify specific pollution reduction activities and timeframes and will be developed in concert with Tributary Action Teams, other stakeholders, and the public.

Statutory Basis or Legal Authority to Act

The authority to develop a TMDL is provided by Title 7 of the Delaware Code, Chapter 60, and Section 303(d) of the Federal Clean Water Act, 33 U.S.C. 1251 et. seq., as amended.

Other Legislation That May be Impacted

None

Notice of Public Workshops and Comment Period

Proposed TMDLs for the Murderkill River and Appoquinimink River Watersheds will be reviewed during a Public Workshop to be held at 6:00 p.m., Monday, June 5, 2006 at the DNREC Auditorium, 89 Kings Highway, Dover, DE.

Proposed TMDLs for the Chesapeake Bay Drainage Basin (Chester River, Choptank River, Marshyhope Creek, Nanticoke River, Gum Branch, Gravelly Branch, Deep Creek, Broad Creek, and Pocomoke River Watersheds), the Inland Bays Drainage Basin (Buntings Branch, Little Assawoman Bay, Assawoman Bay, Indian River Bay, Iron Branch, Indian River, Rehoboth Bay, and Lewes-Rehoboth Canal Watersheds) will be reviewed during a Public Workshop to be held at 6:00 p.m., Tuesday, June 6, 2006 at the University of Delaware Research and Education Center, 16483 County Seat Highway, Georgetown, DE.

Draft TMDL Regulations and technical support documents for these watersheds will be available as of Thursday, June 1, 2006 on the Department’s website (www.dnrec.delaware.gov) by clicking on “TMDLs” under “Information” or by contacting Sam Myoda, Watershed Assessment Section, Division of Water Resources, Department of Natural Resources and Environmental Control, 820 Silver Lake Boulevard, Suite 220, Dover, DE 19904-2464, (302) 739-9939, facsimile: (302) 739-6140, email: (samuel.myoda@state.de.us).

The Department has developed these draft regulations pursuant to a federal Consent Decree that requires the establishment of these TMDLs by the end of Calendar Year 2006. In order to comply with the ambitious schedule set by the Court Order, the Department must receive comments as early as possible in the regulatory development process. Hence, the Department is requiring that written comments on the proposed regulations be submitted no later than 4:30 PM, Friday, June 30, 2006, in order to be considered. After consideration of the written public comments, the Department, upon public notice, will schedule a Public Hearing.

Please send written comments to Sam Myoda, Watershed Assessment Section, Division of Water Resources, Department of Natural Resources and Environmental Control, 820 Silver Lake Boulevard, Suite 220, Dover, DE 19904-2464, (302) 739-9939, facsimile: (302) 739-6140, email: (samuel.myoda@state.de.us).

7412 Total Maximum Daily Loads (TMDLs) for Nutrients for the Chester River Watershed in Delaware

1.0 Introduction and Background

Water quality monitoring performed by the Department of Natural Resources and Environmental Control (DNREC) has shown that the Chester River is impaired by high levels of bacteria, elevated levels of the nutrients nitrogen and phosphorous, and low dissolved oxygen, and that the designated uses are not fully supported by water quality in the stream.

Section 303(d) of the Federal Clean Water Act (CWA) requires states to develop a list (303(d) List) of waterbodies for which existing pollution control activities are not sufficient to attain applicable water quality criteria and to develop Total Maximum Daily Loads (TMDLs) for pollutants or stressors causing the impairment. A TMDL sets a limit on the amount of a pollutant that can be discharged into a waterbody and still protect water quality. TMDLs are composed of three components, including Waste Load Allocations (WLAs) for point source discharges, Load Allocations (LAs) for nonpoint sources, and a Margin of Safety (MOS).

DNREC listed Chester River on several of the State’s 303(d) Lists and proposes the following Total Maximum Daily Load regulation for nitrogen and phosphorous, and Enterococcus bacteria.

2.0 Total Maximum Daily Loads (TMDLs) for the Chester River Watershed in Delaware

Article 1. The nonpoint source nitrogen load in the entire watershed shall be capped at the 2001-2003 baseline level. This shall result in a yearly-average total nitrogen load of 708 pounds per day.

Article 2. The nonpoint source phosphorus load in the entire watershed shall be reduced by 40 percent from the 2001-2003 baseline level. This shall result in reducing the yearly-average total phosphorous load from 54.6 pounds per day to 32.3 pound per day.

Article 3. The nonpoint source bacteria load in the entire watershed shall be reduced by 75.6% from the 1997 – 2005 baseline levels. This shall result in reducing a yearly-mean bacteria load from 1.9E+11 CFU per day to 4.6E+10 CFU per day.

Article 4 3. Based upon water quality model runs and assuming implementation of reductions identified by Articles 1 through 3, DNREC has determined that, with an adequate margin of safety, water quality standards will be met in Chester River.

Article 5 4. Implementation of this TMDL Regulation shall be achieved through development and implementation of a Pollution Control Strategy. The Strategy will be developed by DNREC in concert with the Tributary Action Teams, other stakeholders, and the public.
