turbidity or settle to form deposits shall be controlled at levels which will not be inimical or harmful to the

water uses to be protected or to human, animal, plant or aquatic life.

F. When sampling to determine compliance with mass effluent limitations in Part A of this permit, the

discharge flow at the time of sampling must be measured, reco rded and reported on the Discharge

Monitoring Report Form.

G. Instantaneous maximum limitations are imposed to allow for a grab sample to be collected by the

appropriate regulatory agency to determine compliance. The permittee is not required to monitor for the

instantaneous maximum limitation. However if grab samples are collected by the permittee, the results

must be reported.

H. There shall be no net addition of pollutants to non

- contact cooling water over intake values except for heat

and water conditioning additives for which complete information was submitted in the application or is

required to be submitted as a condition of this permit.

I. The discharge may not change the temperature of the receiving stream by more than 2 F in any one hour

period.

J. Total Residual Chlorine (TRC) Minimization

The permittee will ensure that applied chlorine dosag es, used for disinfection or other purposes, are

optimized to the degree necessary such that the total residual chlorine in the discharge does not cause an

adverse stream impact. In doing so, the permittee shall consider relevant factors affecting chlorin e

dosage, such as wastewater characteristics, mixing and contact times, desired result of chlorination, and

expected impact on the receiving water body.

To reduce or eliminate the amount of chlorine discharged into water bodies, the permittee must: (1)

im prove/adjust process controls and (2) improve operation/maintenance practices.

If the Department determines or receives documented evidence levels of TRC in the permittee's effluent

are causing adverse impacts in the receiving water, the permittee shall i nstitute necessary additional steps

to reduce or eliminate such impact.

80 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 data, assumptions and water quality modeling which was

the basis for the WQBELs and will not proceed with optional site

- specific data collection activities

described in Section C of this condition. The WQBELs will be considered final and enforceable

three years after the PED and should be used as the basis for conducting Phase II of the TRE.

b. During the period followi ng permit is suance, and prior to the WQBELs becoming final, the

permittee agrees to conduct site

- specific discharge and/or stream data collection and provide the

Department with data to verify or refine the WQBELs in accordance with the schedule in Section

B.2, herein. If warranted, modified WQBELs will be established through a permit amendment.

Any such permit amendment shall be considered a formal permitting action of the Department

subject to applicable permit modification procedures.

If the permittee fails to select one of these options within 60 days of permit effective date, option A.2.a.

is selected by default. If the permittee selects option A.2.b. and conducts TRE actions within the

schedule in Section B.2 of this condition of the permit, herein , the Department will issue a written

decision by letter or permit amendment. The permittee will have 30 days from the date of receipt of

such written Department letter or decision to file an appeal of the final WQBELs.

If the permittee chooses this option, requests for alternative, site

- specific criteria must be submitted to

the Depart ment 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 D epartment shall not violate any other

applicable water criteria.

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 eve nt, the permittee has the option to demonstrate alternative, facility

specific 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 b e 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 "not3800

- PM

- WSFR0011 Rev. 5/2012

82 detectable" as a WQBEL and including the numeric alternate MDL value for compliance purposes

through the permit modification or renewal process.

D. Phase II TRE Requirements

The permittee should not pr oceed with Phase II until notified by the Department to do so. Depending on

the results of Phase I the WQBELs may need to be modified or Phase II may not be necessary.

1. Source Reduction Evaluation

In addition to those items in C.1 above, as part of Ph ase 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

pollutan ts.

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 alternative s)

and their ability to comply with the final WQBELs 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, t he request must be submitted with

Phase II of the TRE report. Forms are available from the Department to be used for any such

requests.

implemented at the time that the SWPP is submitted3800

- PM

- WSFR0011 Rev. 5/2012

Pe rmit Permit No. PA0004472

87 If after one year of sampling following complete implementation of the SWPPP , the permittee can

demonstrate that implementation of the SWPPP has resulted in an exclusively uncontaminated storm

water runoff discharge, the permittee may submit an application to amend this NPDES permit

accordingly. In order for its application to be successful, the permittee must demonstrate that the

characteristics of the storm water runoff have changed significantly and that only uncontaminated

storm water runoff is being discharged from the outfall or outfalls in question.

If, within two years fr om the effective date of this Permit, the permittee has not demonstrated that

implementation of the SWPP has resulted in only uncontaminated stormwater runoff discharges from

all of the stormwater outfall, then the permittee shall submit an application for a Water Quality

Management Part II Permit, authorizing construction and operation of treatment technology for the

pollutants in those discharges. The permittee shall construct and operate the treatment technology as

approved by the Department in the Wate r Quality Management Part II Permit, and shall achieve

compliance with the final effluent limitations on or before October 15, 2015.

Beginning 90 days after the effective date of this Permit, and continuing every 90 days thereafter, the

permittee shall su bmit progress reports documenting the activities it has undertaken in compliance with

this paragraph. The permittee shall continue to submit these quarterly progress reports until either ( 1)

this permit has been amended to delete the stormwater outfalls; or (2) the treatment technology

authorized in the Water Quality Part II Permit is fully operational and the discharges from the

stormwater outfalls are in compliance.

G. Within 90 days of the effective date of this Permit, the permittee shall survey the pla nt 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 determi ne whether there are any non

- stormwater contributions to them.

If the permittee identifies any non

- stormwater contributions to those Outfalls or if Part A of the permit

authorizes the discharge of non

- stormwater sources, then the permittee shall sample th e non

stormwater component of the discharge. The permittee shall collect three dry weather samples of

discharges from each of these outfalls and shall cause those samples to be analyzed for fluoride.

If, as a result of the survey described in the prece ding paragraph, the permittee discovers that there

are any outfalls that discharge non

- stormwater sources that are not authorized in Part A of the permit,

the permittee shall survey the plant to identify the sources of the non

- stormwater discharges, and

i mplement 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 accompany the report described in the following paragraph.

Within 24 0 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 of this 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 i nto effect. The report shall

contain the analytical results pertaining to any samples taken of any non

- stormwater discharges. In

the event that the permittee identifies sources that are not authorized in Part A of this permit, then the

report shall be ac companied by the necessary NPDES permit amendment application, requesting

authorization to discharge the unauthorized, non

- stormwater discharges.
