Re: Wastewater Volume Review for Permit Number 386 Located at 2605 West Wayzata Boulevard
As part of the MCES Service Availability Charge (SAC) policy, all industries holding an Industrial
Discharge Permit are subject to a wastewater volume review one year prior to the expiration of their
permit. SAC is a "connection" fee which has been levied since 1973 for new connections or increased
volume discharged by existing users to the Metropolitan Disposal System (MDS). 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.
Three years ago, the first wastewater volume review for your facility 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.
Washington Scientific will not be required to purchase additional SAC at this time.
If you have questions, please call Mark S. Pierson at(651) 602-4707.
Sincerely,
O 14.

Wastewater Volume Review
Industrial Discharge Permit Renewal
Company Name Washington Scientific
Permit Number 386
Permit Expiration Date August 2000
SAC equivalent of the Jan - Jun , 19 99 21 Units
Self-Monitoring Report.
(Total wastewater volume/total number of
operating days equals average daily waste-
water volume. Each SAC unit equals 274 gallons)
Modified SAC Baseline Value 64 Units
(MCES policy determined the SAC baseline
value to be the SAC equivalent of the volume
repoited 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.)
Current wastewater volumes do not exceed the modified baseline value. The permit renewal process will follow
past procedures. This review is complete.
* MCPS SAC purchased records may not be current, therefore, the credit value may be revised to account for
unidentified credits, if the permittee rovide proof of their existence.
