Mr. Tracy Siglin Exelon Generation Company 200 Exelon Way Kennett Square, PA 19348 Re: Limerick Generating Station 1W PAOO 1926 Amendment No. 2 File Type: NPDES Limerick Township Montgomery County

Dear Mr. Siglin:

Your amendment is enclosed.

A The discharge limitations and monitoring requirements in your NPDES permit are also typed on the original Discharge Monitoring Report (DMR) that is attached to the permit. That original DMR is provided as a master, so do not write on it, but rather: (1) make copies of it; (2) after doing the sample analyses and flow measurements required by the permit, fill out all the empty blocks on one of the copies by following the instructions on the back of the original DMR; and (3) make copies of the filled completed DMR and send one to each of the addresses listed in Part C of the permit.

This amendment reflects removal of Outfall 101. Also, on page 16 of the permit, a list of chemical additives is updated.

Any person aggrieved by this action may appeal, pursuant to Section 4 of the Environmental Hearing Board Act, 35 P.S. Section 7514, and the Administrative Agency Law, 2 Pa.C.S. Chapter 5A, to the Environmental Hearing Board, Second Floor, Rachel Carson State Office Building, 400 Market Street, P.O. Box 8457, Harrisburg, PA 17105-8457, 717-787-3483. TDD users may contact the Board through the Pennsylvania Relay Service, 800-654-5984. Appeals must be filed with the Environmental Hearing Board within 30 days of receipt of written notice of this action unless the appropriate statute provides a different time period. Copies of the appeal form and the Board's rules of practice and procedure may be obtained from the Board. The appeal form and the Board's rules of practice and procedure are also available in braille or on audiotape from the Secretary to the Board at 717-787-3483.

This paragraph does not, in and of itself, create any right of appeal beyond that permitted by applicable statutes and decisional law.

An Equal Oppornunity Employer Printed on Recycled Paper

Mr. Tracy Siglin IF YOU WANT TO CHALLENGE THIS ACTION, YOUR APPEAL MUST REACH THE BOARD WITHIN 30 DAYS. YOU DO NOT NEED A LAWYER TO FILE AN APPEAL WITH THE BOARD.

IMPORTANT LEGAL RIGHTS ARE AT STAKE, HOWEVER, SO YOU SHOULD SHOW THIS DOCUMENT TO A LAWYER AT ONCE. IF YOU CANNOT AFFORD A LAWYER, YOU MAY QUALIFY FOR FREE PRO BONO REPRESENTATION. CALL THE SECRETARY TO THE BOARD (717-787-3483) FOR MORE INFORMATION.

If you have any questions, please call Mr. Sohan Garg at 484-250-5197.
