Re: Commonwealth Edison Company Byron Nuclear Power Station g
NPDES Permit No. ILOO48313 Modification of NPDES Permit Gentlemen:
The Illinois Environmental Protection Agency has reviewed the request for modification of the above-referenced NPDES Permit and issued a public notice based on that request.
The final decision of the Agency is to modify the Permit as follows:
1.
Add the.025 MGD intermittent discharge of secondary steam system (non-radioactive) process water to Outfall 001.
2.
Addition of an intermittent (once every 5-10 years) discharge of 0.16 MGD steam generator (s) process wastewater and accompanying chemical metal cleaning / passivation agents EDTA (Ethylenediamine Tetraacetic Acid) and hydrazine or Nalco Elimin-0x to Outfalls 001(a), 001(c), and 001(e) known as Domineralizer Regenerant Waste, Wastewater Treatment Plant Effluent, and Stormwater Runoff Basin, respectively.
3.
Change Special Condition #9 to allow discharge of chemical metal cleaning agents EDTA. Eli6n-Ox and/or hydrazine, and associated rinses at Outfalls 001(a), 001(c), u 001(e) once every 5-10 years during the steam generator (s) clea oc process.
Following the public notice period, the contributory waste scream #5 under Outfall 001(a) now indicates that an approximate flow of 0.16 MGD of steam generator (s) cleaning process waste is discharged once every 5-10 years.
4 Change Special Condition #12 to apply sampling requirements during discharge of steam generator cleaning / passivation solution and associated rinses containing hydrazine and to restrict usage of hydrazine during D
normal steam generator lay-up unless thTpermit is modified to allow its use.
Following the public notice period, the last sentence was changed to read:
"The Permittee shall submit a letter to the Agency requesting a modification to this permit if hydrazine is to be used during normal steam generatt.t !ay-up."
5.
Following the public notice period, the term " lay-up" was removed in the sentences describing metal parameters to be limited during steam generator (s) cleaning process periods on the effluent l im;tations and monitorirq pages for Outfalls 001(a), 001(c), and 001(e).
Mned n necyclea psoer
K Pag'e 2 6.
Following the public notice period, the limit for iron (total) was changed to 1.0 mg/l for Outfalls 001(a), 001(c), and 001(e) pursuant to 40 CFR
)
423.12(b)(5).
Also, the limits for copper, chromium (hexavalent),
chromium (total), lead, nickel and zine (total) were changed to reflect the applicable effluent standards of 35 Ill. Adm. Code 304.124.
7.
Following the public notice period, Special Condition 17 was added to read: "The samples taken in compliance with the steam generator (s) cleaning process monitoring requirements chall be taken at a point representative of the discharge, but prior to mixing with any other waste water and storm water runoff.
If the permittee requires further treatment within the station's wastewater treatment system [0utfall 001(c)] in order to comply with limits, the steam generator (s) cleaning wastes shall not be co-treated with other wastewaters (except for incidental amounts) unless this permit has been modified to allow for such co-treatment." Special Condition 17 applies to samples for all parameters taken in compliance with the steam generator (s) cleaning process monitoring requirements, not just copper and iron.
Enclosed is a copy of the modified Permit.
You have the right to appeal this modification to the Illinois Pollution Control Board within a 30 day period following the modification date shown on the first page of the permit.
Should you have any question or comments regarding the above, please contact Fred Rosenblum of my staff.

Containment - Storage within berms or other secondary containment devices to prevent leaks and spills from entering storm water runoff; ii. Oil & Grease Separation - Oil / water separators, booms, skimers or other methods to minimize oil contaminated stonn water discharges; lii. Debris & Sedirm t Control - Screens, booms, sediment ponds or other methods to reduce debris and sediment in storm water discharges; iv.
Waste Chemical Disposal - Waste chemicals such as antifreerw, degreasers and used oils shall be recycled or disposed of in an approved manner and in a way which prevents them from entering stonn water discharges, Storm Water Diversion - Storm water diversion away from materials manuf acturing, v.
storage and other areas of potential storm water contam'. nation; vi.
Covered Storage or Manuf acturing Areas - Covered fueling operations, materials manuf acturing and storage areas to prevent contact with storm water.
6.
Sediment and Eronun Prevention - The plan shall identify areas which due to topography, activities, or other f actors, have a high potential for significant soil erosion and describe measures to limit erosion.
7.
Employee Training - Employee training programs shall inform personnel at all levels of responsibility of the coraonents and goals of the storm water pollution control plan.
Training should address topics such as spill response, good housekeeping and material management practices. The plan shall identify periodic dates for such training.
8.
Inspection Procedures - Qualified plant personnel shall be identified Ao inspect designated equipment and plant areas. A tracking or follow-up procedure shall be used to ensure appropriate response has t,een taken in typonse to an inspection. Inspections and
_D maintenance activities shall be documented and recorded G.
The permittee shall conduct an annual f acility inspection to verify that all elements of the plan, including the sit 6 map, potential pollutant sources, and structural and non-structural controls to reduce pollutants in industrial storm water oischarges are accurate. Observations that require a response and the apprupriate response to the observation shall be retained as part of the plan. Records documenting significant observations made during the site inspection shall be submitted to the Agency in accordance with the reporting requirements of this permit.
H.
This plan should briefly describe the appropriate elements of other program requirements, including Spill Prevention Control and Countermeasures (SPCC) plans required ur sr Section 311 of the CWk and the regulations promulgated thereunder, and Best Management Prog ams under 40 CFR 125.100.

16.
The Agency has determined that the effluent limitations in this permit constitute BAT /BCT for storm water which is treated in the existing treatment f acilities for purposes of this perinit reissuance, and no pollution prevention plan will be required for such storm water. In addition to the chemical specific monitoring required elsewhere in this permit, the permittee shall conduct an annual inspection of the f acility site to identify areas contributing to a storm water discharge associated with industrial activity, and determine whether any facility modifications have occurred which result in previously-treated storm water discharget no longer receiving treatment. If any such discharges are identified the permittee shall request a modification of this permit within 30 days after the inspection. Records of the annual inspection shall be retained by the permittee for the term of this permit and be made available to the Agency on request.
