Re: Wastewater Volume Review for Percnit Number 91 - Located at 610 Opperman Drive
As part of the MCFS Seivice Availability Charge (SAC) policy, all industries holding an Industrial
Discharge Permit are subject to a wastewater volume review one year prior to the eacpiiarion of
their pernut. SAC is a"connection" feE which has been levied since 1973 for new cnnnections or
increased volume dischazged by exisUng users to the Mehopolitan Disposal System (NIDS). SAC
revenue is used to pay for the unused reserve capacity portion of debt service for capital
improvements.
The wastewater volume review serves as a method for detecting wastewater volume increases from
a facility. Current wastewater volumes are converted to a SAC equivalent and compared to a SAC
baseline value. Any increases over the baseline value, or the value for SAC credits, whichever is
greater, have the potential to be assessed SAC.
Thnee years ago, a wastewater volume review for your faciliry took place. At that time, wastewater
volumes from your facility were noted to be below SAC baseline and/or SAC credit levels. A
current evaluation of wastewater flows from your facility indicates that discharge volumes remain
below the SAC baseline.
Please find enclosed a Wastewater Volume Review Worksheet specifying the results of the review.
West Group will not be required to purchase additional SAC at this time. If you have questions,
please call Berhane D. Worku at 651-602-4717.

Wastewater Volume Review
Industrial Discharge Permit Renewal
Company Name West Gmup
Permit Number
Permit Fxpiration Date
SAC equivalent of the July - Dec., 2000
Self-Monitoring Repon.
(Total wastewater volume/total number of
operaring days equa]s average daily waste-
water volume. Each SAC unit equals 274 gallons)
Modified SAC Baseline Value
(MCES policy determined the 5AC baseline
value to be the SAC equivalent of the volume
reported in the final self-monitoring report
for 1991. The modified SAC baseline value
represents the SAC baseline value, plus any
SAC units purchased after the 1991 baseline
date, or the value for SAC credits*, whichever
is greater.)
179 Units
206 Units
Current wastewater volumes do not exceed the modified baseline value. The permit renewal
pmcess will follow past procedures. Tlris review is complete.
* MCES SAC purr-hased records may not be current, therefore, the credit value may be revised to
account for unidentified credits, if the permittee can pmvide proof of their exastence.
