E.

The limit for zinc was based on a single sample jnalysis. Nevertheless, the permittee agreed to the imposition of a final water quality based effluent limitation, for zinc at Outfallf012 but needed a limited amount of time to further assess the quality, of the discharge and if necessary, plan for and construct additional treatment facilities. This is a cooling tower blowdown from the HVAC

-.system for the emergency respome,building.' -The chromium limit, is deleted from the permit..

Unlike zinc, there were -]ow levels of chromiumin thip discharge.

Condition C-21 of the permit has been modified. The modified condition also allows additional time to collect the routine storm water samples inthe event-that they cannot be collected during the first 30 minutes of a storm event.

The modified condition also allows the permittee to sample, during the first calendar quarter

'after the permit is amended, Outfalls 012"and 013 which are parkimg lot drains. The Department will then determine based upon the aialytical i'esults if 'additional monitoring is necessary.

R ThePermittee agreed t'o sample and analyze all intermal nri6niforhig ooints. Foi those IMPs where treatment facilities exist, one (1) influent and three (3) effluent samples will be collected.

At all other IMPs, three (3) effluent samples.will be collected., Condition C-22 of the permit has been modified, accordingly. The modification of this condition also allows additional time to collect this data. The Department and FENOC agreed, at the time the appeal was filed, to delay the imposition of the deadline pending resolution of the appeal.

S.

Since the permittee has agreed to final water quality based effluent limits,' the TRE Condition (C-25) will remain in the permit.

In addition to those change6 outlined above, the permitt~e has requested that IMP1 10 be deleted from the permit. The permit is modified in response to this request.

Preliminary Water Quality Based Effluent Limitations (PWQBELs)

I1.

Based on the discharge and stream data currently available to the Department, the PWQBELs denoted with an asterisk (*) on page 2cc of 14 are necessary to protect the receiving stream uses designated in Chapter 93 of the Department's Rules and regulations. The Final WQBELs denoted with a double asterisk (* *) were developed based on sufficient discharge and stream data, and further site-specific data collection is not necessary. Therefore Sections A.2, C.2 and C.3 below do not apply to the ** parameters.

2.

Within 60 days of the permit effective date (PED), the permittee must submit notification to the Department verifying one of the following options has been selected:

a.

The permittee accepts the Department's modeling which was the basis for the PWQBEL's and will not proceed with the optional site-specific data collection activities described in C.2 and C.3 below. In this case, the PWQBELs on page 2cc of 14 will be considered final and enforceable within three years of PED as currently shown on page 2cc of 14, and should be used as the basis for Phase II of the TRE.

or

b.

The permittee agrees to conduct the optional site-specific discharge or stream data collection described in C.2 or C.3 below that would provide the Department with data for use in verifying and refining the PWQBELs.

In this case, the PWQBELs on page 2cc of 14 would not go into effect until the Department modifies the permit. The permittee will be notified of the results of the Phase I review, at which time the permittee can proceed with Phase II.

If the permittee fails to select one of these options within 60 days of the PED, option "a" is selected by default.

3.

In either case, the Permittee must conduct a TRE as outlined below. Phase I of the TRE has both required and optional components. The Department will review the Phase I report and may establish final WQBELs and compliance schedules through a permit modification. Any such permit modification shall be considered a formal permitting action by the Department. The permittee shall submit progress reports to the Department as shown on the TRE schedule below outlining the progress being made to achieve the final WQBELs and/or modify the PWQBELS.

PART C DRAFT Page 14k of 14 Permit PA0025615 B.

TRE Submission Requirements

1.

The TRE shall be developed to:

a.

confirm and quantify the presence of the pollutants in the discharge with PWQBELs.

b.

verify or refine the modeling data and/or assumptions used to develop the PWQBELs.

c.

identify sources of the pollutants with final WQBELs or PWQBELS.

d.

recommend management practices, wastewater treatment technologies, or other control techniques to reduce or eliminate these pollutants.

2.

A copy of the Department's "Guidelines for Conducting a Toxics Reduction Evaluation" is enclosed for your use. The TRE and associated reports shall be completed and submitted in accordance with the following schedule:

Action Date

a.

submit notification specified in A.2 above

b.

submit work plan for conduct ing Phase I

c.

start Phase 1

d.

submit complete Phase I report (3 copies)

e.

start Phase II

f.

submit complete Phase II report

g.

progress reports within 60 days of PED within 90 days of PED within 120 days of PED within 18 months of PED within 30 days of notice from the Department to proceed with Phase II within 180 days of notice to proceed with Phase II every three months starting 120 days after PED

Phase I

1.

The permittee is required to submit Phase I of the TRE consisting of the following components:

a.

influent and effluent quality review

b.

source inventory and evaluation

c.

source reduction evaluation

d.

implementation of pollution prevention, sound housekeeping practices, and other management practices in accordance with 40 CFR 125 Subpart K.

2.

The permittee has the option of providing all or some of the following site specific data as part of Phase I for use in verifying and refining the PWQBELs:

- discharge hardness

- discharge pollutant concentration and variability

- design discharge flow

- discharge mixing characteristics

- pollutant fate characteristics

- stream width, depth and slope

- stream velocity

- ambient stream data for pollutants, pH, temperature

- instream hardness

- water intake quality and quantity

- treatment plant influent pollutant concentrations

- chemical translators

- Water Effects Ratio (WER)

The permittee should contact the Department for guidance in determining which of the above data will have a significant impact on the PWQBELs and also for protocols on collecting and submitting the data. The Department will determine the adequacy of any site-specific data submitted and advise the permittee accordingly. If initial review of the submitted data suggests that additional data collection is necessary, the Department will so advise the permittee. The Department will notify the permittee what effect, if any, the data have on the PWQBELs using the procedure outlined in A.3 above.

3.

Site-Specific Criteria The PWQBELs for copper are necessary for the protection of aquatic life or human health. The permilttee mhi"y request an opportunity to demonstrate alternative, site-specific cr'iteria for these pollutants. The procedures for carrying out such demonstrations munstreceive written approval in advance by the Department and must be in accordance with the requirements of Section 93.8 of the Departments Rules and Regulations.

If the permittee chooses this option, requests for alternative, site-specific criteria must be submitted to the Department as part of the Phase I TRE report. Where the demonstration results in more stringent limitations than those previously established by the Department, the more stringent limitation will apply. Any less stringent limitations which are approved by the Department shall not violate any other applicable water criteria.

4.

Alternative Site Specific Method Detection Limits (MDL)

In some cases, the PWQBEL 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, facility-specifi6 MDLs to account for 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 or renewal process.

D.

Phase II The permittee should not proceed with Phase II until notified by the Department to do so.

Depending on the results of Phase I the PWQBELs may need to be modified or Phase II may not be necessary.

I1.

Source Reduction Evaluation In addition to those items in C.1 above, as part of Phase II, the permittee must conduct source reduction evaluations including recycle, reuse, and process/chemical substitution. The intent of this portion of the TRE is to investigate and implement all low-cost, non-structural alternatives to reduce pollutants.

PART C Page l4n of14 DRAFT Permit PA0025615

2.

Final WQBEL Compliance Strategies and Schedule A complete TRE report must consist of identification and assessment of all available pollution control options (Best Management Practices and/or treatment technologies and other structural alternatives) and their ability to comply with the PWQBELs and/or final WQBELs on page 2cc of 14 or other WQBELs identified in response to Phase I. The permittee must select a specific pollution control option that will achieve the applicable WQBELs and specify a schedule for the implementation of this option.

3.

Section 95.4 Time Extension Requests In some cases, the final WQBEL may not be technologically achievable using any combination of control options. In this event, the permittee has the option of requesting an extension of time to achieve the WQBEL, provided the permittee demonstrates eligibility for time extension under the requirements contained in 25 Pa. Code 95, Section 95.4 of the Department's Rules and Regulations. If the permittee elects to submit the 95.4 time extension request, the request must be submitted with Phase II of the TRE report. Forms are available from the Department to be used for any such requests.
