groundwater quality. The location and construction details for these wells shall
be approved by the Washington Regional Office, from which a well construction
permit must be obtained.
31. The existing monitor wells No. 1 and No. 3 and the two (2) new monitor wells
shall be sampled initially after construction (and prior to waste disposal

Water Level
The measurement of water level must be made prior to sampling for the remaining
parameters.
If TOG concentrations greater than 10 mg/l are detected in any downgradient

the downgradient wells shall be subject to the additional sampling and analysis
as described above.
The analytical methods used for TOX must be capable of detecting the total of all

concentration at or above the method detection limit (MDL) must be identified and
quantified utilizing EPA methods 601, 602, 604 and 611.

effluent quality assigned, a complete application shall be submitted to DEM
within 30 days that will allow the wastewater treatment plant to maintain the
assigned effluent quality.

33. The following monitoring shall be performed:
1) '-BOD - 2/month - effluent
2) TSS - 2/month - effluent
3) -Fecal Coliform Bacteria - 2/month - effluent
4) *Chlorine Residual - daily - effluent
5) Flow - daily - influent or effluent
f) ,.Tot. Nitrogen (NH3, NO2, NOV organic) - monthly -
effluent
7) **Intensity of LTV irradiation (UV dose)
Microwatt --seconds per square centimeter (uW-Sec/cm2)
8) upH - 2/month - effluent
Monitoring required only when chlorination system in use
** Monitoring required only when UV system in use
All monitoring shall be submitted to the Washington Regional Office no later than
30 days following the end of the monitoring month.
34. Within four (4) months after the startup of the subject facilities, the Permittee
