The Department will determine the adequacy of any site-specific data submitted and advise the permittee accordingly. If initial review ofthe submitted data suggests that additional data collection is necessary, the Departmentwill so advise the permittee. The Departmentwill notifythe permitteewhat effect, ifany, the data have on theWQBELs using the procedure outlined in A.2 above. 3. Site-Specific Criteria The permittee may request an opportunity to demonstrate alternative, site-specific criteria for any pollutants with WQBELs. The procedures for carrying out such demonstrations must receive written approval in advance by the Department and must be in accordance with the requirements of Section 93.8 ofthe Department's Rules and Regulations. Ifthe permittee chooses this option, requests for alternative, site-specific criteria must be submitted to the Department as part ofthe Phase ITRE report. Where the demonstration results in more stringent limitationsthan those previously established by the Department, the more stringent limitationwill apply. Any less stringent limitations which are approved by the Department shall not violate any other applicablewatercriteria. 4. Alternative Site Specific Method Detection Limits (MDL) In some cases, the WQBEL may be less than the Method Detection Level (MDL) in the Department's Policy, 25 PA Code 16. In this event, the permittee has the option to demonstrate alternative, facilityspecific MDLs to accountfor analytical matrix interference associated with the wastewater in question. The procedures for determining MDLs, published as Appendix B in 40 CFR 136 must be followed and complete documentation provided. The request for approval of alternative facility-specific MDLs including all documentation required to support such a request must be submitted to the Department with the Phase I TRE report. The Department may grant a facility specific MDL by specifying "not detectable" as a WQBEL and including the numeric alternate MDL value for compliance purposes through the permit modification orrenewal process.

### Beginning 90 days afterthe effective date ofthe permit issued to US Steel on September28, 2012, and continuing every 90 daysthereafter, the permittee shall submit progress reports documenting the activities it has undertaken in compliance with this paragraph. The permitteewill submitafinal report ofthe effectiveness ofthe SWPPPand ofits progresstoward meeting the goals no laterthan 180days priortothe Permit Expiration Date. The stormwater goal fortotal cadmium may be lessthan the reporting limitforthe analytical method used during testing (EPA Method 200.7). The Departmentwill interpretthose instanceswhere the measured concentration is lessthan the reporting limitas meeting the listed goalfortotal cadmium, so long as EPA Method 200.7 is used to monitorthe stormwaterdischarges. F. Within 90 days ofthe effective date ofthis Permit, the permittee shall survey the plant to identify the potential sources of fluoride in the following storm water runoff outfalls: 001A, 009, 010, 011, 022, 054A, 068, 085, 086, 087, 088, and 089. The permittee shall conduct dry weather observations of these outfalls often enough to determinewhetherthere are any non-stormwater contributions to them. If the permittee identifies any non-stormwater contributions to those Outfalls or if Part A ofthe permit authorizes the discharge of non-stormwater sources, then the permittee shall sample the nonstormwater component of the discharge. The permittee shall collect three dry weather samples of dischargesfrom each ofthese outfalls and shall cause those samplesto be analyzedforfluoride. If, as a result ofthe survey described in the preceding paragraph, the permittee discovers that there are any outfalls that discharge non-stormwatersources that are not authorized in Part A ofthe permit, the permittee shall survey the plant to identify the sources of the non-stormwater discharges, and implement measures to eliminate those non-stormwater sources. If the non-stormwater discharges cannot be eliminated, then the permittee shall submit an application to amend this Permit accordingly. This submission shall accompanythe report described in the following paragraph. Within 240 days of the effective date of this permit, the permittee shall submit a written report to the Department outlining its findings. In the report the permittee shall: (a) identify the sources of wastewater contributing fluoride to the discharges; (b) describe those measures that were tried after issuance ofthis permit and their effectiveness in eliminating or reducing fluoride in the discharges; and (c) describe and submit schedules for those measures that will be put into effect. The report shall contain the analytical results pertaining to any samples taken ofany non-stormwater discharges. In the eventthatthe permittee identifies sources that are not authorized in Part A ofthis permit, then the report shall be accompanied by the necessary NPDES permit amendment application, requesting authorization to dischargethe unauthorized, non-stormwaterdischarges.

By email dated November 20, 2014, EPA provided the following comment on the draft permit. DEP's response is provided following that comment. EPA Comment: EPA has chosen to perform a limited review based on the CWA 

### § 316(a) requirements. As a result ofour limited revjew, weofferthe following comments. 1. According to Part

### A., the permittee shall complywith the temperature requirements by fall2017 instead offall2015. Part C.I.B. proposes temperature discharges requirements that can be used to request a thermalvariance. Before a thermal variance can be granted, 40 CFR 

### §§ 125.72 and 125.73 require the permittee to demonstrate that the otherwise applicable thermal discharge effluent limit is more stringent than necessary to assure the protection and propagation ofthe waterbody's balanced indigenous population (BIP) ofshellfish, fish and wildlife. With respect, but not limited to, the renewal ofa prior CWA

### § 316(a)thermalvariance, it is essential that PADEP requires applicantsto provide as much ofthe information described in 40 CFR 

### § 125.72(a) and (b) as necessary to demonstrate that the · alternative effluent limit assures the protection and propagation ofthe BIP. Does this facility have or requested a thermalvariance? Please explain in thefact sheetfollowing the requirements and rationale listed above. Pleaseaddress ourcomments and recommendations, and provide us with anychanges to the draft permit, fact sheet, and/or permitcomponents. Response to EPA Comment The Clairton Plant does not have a thermal variance and United States Steel Corporation ("USS Corp.") does not intend to request athermal variance. As required by Part C.I.B. ofthe 2012 NPDES permit renewal forthe Clairton Plant, USS Corp. submitted a final report to DEP summarizing the results ofthe Thermal Work Plan. In the final reportdated September 12, 2014, USS Corp. contends thatthe site-specific information it collected by implementing the Thermal Work Plan demonstrates th;:Jt the water quality-based effluent limitations for temperature included in the 2012 NPDES permit and maintained in this amendmentare not necessary.
