3. The permittee shall perform testing using the following dilution series: 4%, 8%, 16%, 58%, and 100%

effluent, with a control, where 16% is the facility-specific Target In-Stream Waste Concentration (TIWC).

4. The determination of whether a test endpoint passes or fails shall be made using DEP's WET Analysis Spreadsheet (available at www.depweb.state.pa.us/wett) by comparing replicate data for the control with replicate data for the TIWC dilution or any dilution greater than the TIWC.

5.

The permittee shall submit only valid WET test results to DEP.

B. Test Frequency and Reporting

1. WET testing shall be conducted quarterly, beginning within 30 days of the permit effective date. Tests shall be completed within calendar quarters, i.e., one test each during the periods of January 1 -

March 31, April 1 - June 30, July 1 - September 30, and October 1 - December 31. A complete WET test report shall be submitted to the DEP regional office that issued the permit within 30 days of test completion.

A complete WET test report submission shall include the information contained in paragraph H, below.

2.

If a test failure is determined for any endpoint during quarterly monitoring, the permittee shall initiate a re-test for the species with the failure, at a minimum, within 45 days of test completion. All endpoints for the species shall be evaluated in the re-test. The results of the re-test shall be submitted to the DEP regional office that issued the permit.

4.

If a passing result is determined for all endpoints in a re-test, the permittee continue with quarterly monitoring, as applicable.

5.

If there is a failure for one or more endpoints in a re-test, the permittee shall continue quarterly WET testing for both species. The results of all tests shall be submitted to the DEP regional office that issued the permit.

In addition, the permittee shall initiate a Phase I Toxicity Reduction Evaluation (TRE) as specified in paragraph C, below.

6. The permittee must report the results of each test endpoint that has a WET limit in Part A of this permit on the Discharge Monitoring Report (DMR). Test results shall be reported on the DMR in terms of acute or chronic Toxicity Units (TUa or TUc), where TUa is used for acute tests and TUc is used for chronic tests. If DEP's WET Analysis Spreadsheet indicates a passing result for an endpoint, report the value obtained from the expression "I/ITIWC", which is equivalent to the permit limit.

If the Spreadsheet indicates a failure, report the value obtained from the expression '> 1/TIWC". If a dilution higher than the TIWC dilution is used for the comparison with the control, report the value obtained from the expression "l/dilution". For example, an acute test endpoint failure at a TIWC dilution of 50%

would be reported as "> 2.0 TUa" (1/0.5).

7. The permittee shall attach a completed WET Analysis Spreadsheet for the latest four consecutive WET tests to the NPDES permit renewal application that is submitted to DEP at least 180 days prior to the permit expiration date.

PCB MONITORING A. On April 7, 2007, the U.S. Environmental Protection Agency (EPA), Region Ill, established a Total Maximum Daily Load (TMDL) for Polychlorinated Biphenyl (PCB) for the Schuylkill River, which was listed on Pennsylvania's 1996 303(d) list of impaired streams as impaired due to the presence of elevated PCB concentrations found in fish tissue. PCBs are a group of synthetic chemicals that consist of 209 individual compounds (known as congeners). The Schuylkill River's PCB TMDL was established using a water quality criterion of 0.044 ng/L for PCBs.

B. Implementation of the TMDL requires that permitted facilities that discharge directly to the Schuylkill River conduct monitoring for PCBs using analytical Method 1668A.

The results of PCB monitoring will be evaluated to determine a need to develop and implement a PCB Waste Minimization and Reduction Program, also known as Pollution Minimization Plan (PMP). For information on how to develop a PMP visit Delaware River Basin Commission's website at http:/lwww.state.ni.usldrbclPMP info.htm.

C. Implementation of the TMDL will be completed in two phases.

Phase I implementation of the TMDL requires that this facility collect and analyze two samples for PCBs utilizing Method 1668A during the first 12 months of this permit.

Phase 11 implementation of the TMDL will involve the development and implementation of a PMP based on the PCB monitoring results. This facility is required to collect and analyze two samples for PCBs utilizing Method 1668A within 12 months from the issuance of this permit.

One sample shall be collected during a wet weather flow period; the second sample shall be collected during a dry flow period. The samples shall be collected from Outfall 001. Sample collection techniques, identification analytical approaches and reporting requirements can be found at http://www.state.nj.us/

drbc/PCBinfo.htm.

D. Within 15 months from the issuance of this permit, the facility shall submit the results of the PCB monitoring to DEP at the address listed below. Upon review of the data collected in Phase I, individual facilities will be directed by the DEP to commence Phase II involving development and implementation of a PMP.
