West Falls utilizes a fume suppressant, Cancel St-45, 

manufactured by Plating Resources Inc., to maintain a 

surface tension on Tank 1 and 2,( 975 gallon and 315 

gallon chrome plating tanks), of 45 dynes/cm or less. 

This is in accordance with the requirements of 40 cfr 

63.343(c)(5)(ii). The Performance test was conducted 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). Exceedances 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 exceedance occurs as indicated 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.

requirements must be adhered to in such circumstances.

(a) The facility owner and/or operator shall compile and maintain records of all equipment 

maintenance or start-up/shutdown activities when they can be expected to result in an exceedance of any 

applicable emission standard, and shall submit a report of such activities to the commissioner's 

representative when requested to do so in writing or when so required by a condition of a permit issued 

for the corresponding air contamination source except where conditions elsewhere in this permit which 

contain more stringent reporting and notification provisions for an applicable requirement, in which case 

they supercede those stated here. Such reports shall describe why the violation was unavoidable and shall 

include the time, frequency and duration of the maintenance and/or start-up/shutdown activities and the 

identification of air contaminants, and the estimated emission rates. If a facility owner and/or operator is 

subject to continuous stack monitoring and quarterly reporting requirements, he need not submit reports 

for equipment maintenance or start-up/shutdown for the facility to the commissioner's representative.

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

 Air Pollution Control Permit Conditions

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 requested in writing by the commissioner's representative, the 

facility owner and/or operator shall submit a written 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 depending 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/or operator shall take 

appropriate action to prevent emissions which will result 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 pollutants) excused, the specific federal regulation must 

provide for an affirmative defense during start-up, shutdowns, malfunctions or upsets.

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 electrolytic 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 eliminator 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.
