iii. Monitoring Requirements to demonstrate continuous compliance in
accordance with 40 CFR 63.343(c):
A. The Permittee of an affected source shall monitor the surface tension of the
electroplating bath. Operation of the affected source at a surface tension
greater than 40 dynes/cm, as measured by a stalagmometer, or 33 dynes/cm,
as measured by a tensiometer shall constitute noncompliance with the
standards. The surface tension shall be monitored according to the following
schedule:
B. The surface tension shall be measured once every four hours during operation
of the tank with a stalagmometer or a tensiometer as specified in Method
306B, appendix A of 40 CFR Part 63.
C. The time between monitoring can be increased if there have been no
exceedances. The surface tension shall be measured once every four hours of
tank operation for the first 40 hours of tank operation after the compliance
date. Once there are no exceedances during 40 hours of tank operation,
surface tension measurement may be conducted once every eight hours of
tank operation. Once there are no exceedances during 40 hours of tank
operation, surface tension measurement 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 Subpart N is once every 40
hours of tank operation.
D. Once an exceedance occurs as indicated through surface tension monitoring,
the original monitoring schedule of once every four hours must be resumed.
A subsequent decrease in frequency shall follow the schedule laid out in
paragraph(b)(iv)(A)(2) above. For example, if the Permittee had been
monitoring an affected source once every 40 hours and an exceedance occurs,
subsequent monitoring would take place once every four hours of tank
operation. Once an exceedance does not occur for 40 hours of tank operation,
monitoring can occur once every eight hours of tank operation. Once an
exceedance does not occur for an additional 40 hours of tank operation on
this schedule, monitoring can occur once every 40 hours of tank operation.

Permit No. 07680R07
Page 7
iv. Once a bath solution is drained from the affected tank and a new solution
added, the original monitoring schedule of once every four hours must be
resumed, with a decrease in monitoring frequency allowed following the
procedures of paragraph (b)(iv)(A)(2) above.
c. MACT Recordkeeping Requirements - In addition to any other recordkeeping
requirements of the EPA, the Permittee is required to maintain the following records
for an affected source:
