All concentrations from Table 13 of the Supplemental Manual
are based on the Industrial Laundries Average, except where noted
above.
| |
(1) Based off of Hospital Average.
| |
(2) Based off of Truck Cleaners Average.
| |
If the City Engineer determines that any of the above limits
are not achievable for an unpermitted user, an industrial wastewater
discharge permit will be required for the user.

* The MAIL for mercury is calculated by subtracting the total
daily mass of mercury allocated to all unpermitted users from the
no net increase loading established in the table. Mercury loadings
are subject to a no net increase requirement. A mercury monitoring
and compliance program will be implemented to evaluate and maintain
compliance by the industrial users with the no net increase requirement
to both East Side and West Side Wastewater Facilities. Specific mercury
limitations will be imposed upon industrial users, and numeric MAILs
will be set based upon the results of the monitoring and compliance
program.
| |
** The no net increase loading will not be increased above this
value in the future (i.e., as a result of future local limits technical
analyses).
