Section 13.03A.0310 Permit Modification [3.10]
The Plant Manager may modify a discharge permit with or without a request to do so:
to incorporate any ne w or revised federal, state, or local pretreatment standards or requirements;
to address significant alterations or additions to the user’s operation, processes, or wastewater volume or character since the time of the discharge permit issuance in the opinion of the Plant Manager;
where there is a change in the POTW that requires either a temporary or permane nt reduction or elimination of the authorized discharge in the opinion of the Plant Manager;
where there is information indicating that the discharge poses a threat to the POTW, City personne l, any bene ficial sludge use, or the receiving waters in the opinion of the Plant Manager;
because of violation of any terms or conditions of the individual discharge permit;
because of misrepresentations or failure to fully disclose all relevant facts in the permit application or in any required reporting;
because of a revision of or a grant of variance from categorical pretreatment standards pursuant to 40 CFR §403.13;
to correct typographical or other errors in the individual discharge permit; or
to reflect a transfer of the facility owne rship or operation to a ne w owne r or operator where requested; or
for any other reason deemed due and sufficient.
Modification Requests.
Permit modification requests must be verified, signe d by an authorized representative as provided in SMC 13.03A.0305(B) and include a fee as specified in SMC 13.03A.1401 . Submitting a permit modification request does not stay the running of the time within which an administrative appeal from a permit decision must be filed with the City hearing examine r. A permit modification is not required if there is no substantial change in a discharge, no increased pollutants or other conditions upon which modifications may be based, all in the opinion of the Plant Manager. Permit modification requests must address changes in slug control plans and industrial stormwater.
Notice.
If the Plant Manager deems the modification significant, notice is issued in like manne r as an original permit decision and may be appealed in the same manne r as for a permit decision.
