This is in accordance with the requirements of 40 cfr 63.343(c)(5)(ii). The Performance test was c onducted in accordance with 40 cfr part 60.7 on July 1, 2003. Surface tension measurements will be recorded in accordance with 40 CFR 63. 343(c)(5). Ex ceedances of 45 dynes/cm shall constitute noncompliance with the standards. A) The surface tension shall be measured once every 4 hours during operation of the tank with a stalagmometer or a tensiometer as specified in 40 cfr part 63, Method 306B, Appendix A. B) The time between monitoring can be increased if there have been no exceedances. The surface tension shall be measured once every 4 hours of tank operation for the first 40 hours of tank after the compliance date. Once there are no exceedances during 40 hours of tank operation, surface tension measurements may be conducted once every 8 hours of tank operation. Once there are no exceedances during 40 hours of tank operation, surface tension measurements may be conducted once every 40 hours of tank operation on an ongoing basis, until an exceedance occurs. The minimum frequency of monitoring allowed by this subpart is once every 40 hours of tank operation. C) Once an exceedan ce occurs as indi cated through surface tension monitoring, the original monitoring schedule of once every 4 hours must be resumed as described in item B above. Upon discovery of an unusual operating condition or a confirmation of a malfunction, the plating system operator will record the information on the respective monitoring log and take immediate action to implement corrective action through equipment maintenance/repair, chemical addition or procedural changes to address the situation.

(b) In the event that emissions of air contaminants in excess of any emission standard in 6 NYCRR

Air Pollution Control Permit Conditions Page 15 of 19 FINALPermit ID: 9-1466-00047/00003 Facility DEC ID: 9146600047 Chapter III Subchapter A occur due to a malfunction, the facility owner and/or operator shall report such malfunction by telephone to the commissioner's representative as soon as possible during normal working hours, but in any event not later than two working days after becoming aware that the malfunction occurred. Within 30 days thereafter, when requeste d in writing by the commissi oner's representative, the facility owner and/or operator shall submit a wr itten report to the commissioner's representative describing the malfunction, the corrective action taken, identification of air contaminants, and an estimate of the emission rates. These reporting requirements are superceded by conditions elsewhere in this permit which contain reporting and notification provisions for applicable requirements more stringent than those above. (c) The Department may also require the owner and/or operator to include in reports described under (a) and (b) above an estimate of the maximum ground level concentration of each air contaminant emitted and the effect of such emissions dependi ng on the deviation of the malfunction and the air contaminants emitted. (d) In the event of maintenance, start-up/shutdown or malfunction conditions which result in emissions exceeding any applicable emission standard , the facility owner and/oroperator shall take appropriate action to prevent emissions which will resu lt in contravention of any applicable ambient air quality standard. Reasonably available control technology, as determined by the commissioner,. shall be applied during any maintenance, start-up/shutdown or malfunction condition subject to this paragraph. (e) In order to have a violation of a federal regulation (such as a new source performance standard or national emissions standard for hazardous air pollutant s) excused, the specific federal regulation must provide for an affirmative defense during start-up, shutdowns, malfunctions or upsets. Condition 6: Emission Unit Definition Effective between the dates of 05/25/2004 and Permit Expiration Date Applicable State Requirement: 6NYCRR 201-5 Item 6.1: The facility is authorized to perform regulated processes under this permit for: Emission Unit: U-PLAT1 Emission Unit Description: This emission unit consists of a hard chromium plating process and its dedicated exhaust systems. Emissions are generated from electroplating processes conducted in two tanks. The large tank (tank1) is used for hard-chrome plating of steel components, and the small tank (tank2) is operated as a chromic acid recovery tank to purify chromic acid plating solution. These are identified as process CHR. Also included under this emission unit is an evaporator which pumps contaminated ground water from a well located in the plating room, process EVA. Building(s): MAIN PLANT

Notwithstanding the existence of specific air quality standards or emission limits, this prohibition applies, but is not limited to, any particulate, fume, gas, mist, odor, smoke, vapor, pollen, toxic or deleterious emission, either alone or in combination with others.

** ** Emission Unit Level **** Condition 7: Emission Point Definition By Emission Unit Effective between the dates of 05/25/2004 and Permit Expiration Date Applicable State Requirement: 6NYCRR 201-5 Item 7.1: The following emission points are included in this permit for the cited Emission Unit: Emission Unit: U-PLAT1 Emission Point: 00101 Height (ft.): 23 Diameter (in.): 24 Building: MAIN PLANT Emission Point: 00202 Height (ft.): 15 Diameter (in.): 16 Building: MAIN PLANT Condition 8: Process Definition By Emission Unit Effective between the dates of 05/25/2004 and Permit Expiration Date Applicable State Requirement: 6NYCRR 201-5 Item 8.1: This permit authorizes the following regulated processes for the cited Emission Unit: Emission Unit: U-PLAT1 Process: CHR Source Classification Code: 3-09-010-06 Process Description: This emission unit consists of a hard chromium plating

Air Pollution Control Permit Conditions Page 17 of 19 FINALPermit ID: 9-1466-00047/00003 Facility DEC ID: 9146600047 process and its dedicated exhaust systems. Emissions are generated from electroplating processes conducted in two tanks. The large tank (tank1) is used for hard-chrome plating of steel components. Tank1 is ventilated by two opposed slotted hoods that run the length of the tank on each side and merge into the main exhaust manifold directly below the primary suction line to the exhaust fan. The small tank (tank2) is operated as a chromic acid recovery tank utilizing electro lytic diaphragm porous pots to purify chromic acid plating solution. Tank2 is ventilated by two opposed slotted hoods that run the length of the tank on each side and combine to form a branch that ties into the main exhaust man manifold directly below the mist elimin ator in the suction line to the exhaust fan. A fluted frp mist eliminator is located in the main exhaust line upstream of both tanks 1 and 2. The mist eliminator is equipped with a water flushing/cleaning fitting at t he top of the enclosure. A teflon-based fume suppressant is maintained on the surface of both tanks to enhance the shedding of plating solution during parts removal and suppress evaporation losses.

The atmospheric c evaporator is also used to concentrate filtrate generated from the filter press, and return flow from tank2. The concentrated water from the evaporator is returned by gravity to the holding tank for transfer into tank2. Approximately 50 to 70 gallons per day are evaporated from this system. The tank
