Removal of discharge is recommended in three years or new limits (page 2) will apply at that time. Facility must submit an engineering report within 12 months of the effective date of this permit showing no alternative to surface water discharge. instream monitoring has been done for this facility. If this facility is to be closed within the year instream monitoring would not be necessary, however, if there is to be continued discharge for a longer period technical support strongly recommends instream monitoring.
