Re: Wastewater Volume Review for Permit Number 319 - Located at 1500 73rd Avenue NE
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, a 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 dischaazge volumes remain
below the SAC baseline. .
Please find enclosed a Wastewater Volume Review Worksheet specifying the results of the review.
Onan- Technical Center will not be required to purchase additional SAC at this time. If you have
questions, please call Laura Engen at 651-602-4712.
Sincerely,

Wastewater Volume Review
Industrial Discharge Permit Renewal
Company Name Onan-Technical Center
Permit Number 319
Permit Expiration Date 5/31/03
SAC equivalent of the Jan. - Dec., 2001 36 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 99 Units
(MCES policy determined the SAC 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.)
Current wastewater volumes do not exceed the modified baseline value. The permit renewal
process will follow past procedures. This review is complete.
* MCES SAC purchased records may not be current, therefore, the credit value may be revised to
account for unidentified credits, if the permittee can provide proof of their existence.
