Section 310.611  Requirements

for Non-Categorical Users

The Control Authority must require

appropriate reporting from those industrial users with discharges that are not

subject to categorical pretreatment standards.  Significant non-categorical

industrial users must submit to the Control Authority at least once every six

months (on dates specified by the Control Authority) a description of the

nature, concentration, and flow of the pollutants required to be reported by

the Control Authority. If a local limit requires compliance with a best

management practice or pollution prevention alternative, the industrial user

must submit documentation required by the Control Authority to determine the

compliance status of the industrial user.  These reports must be based on

sampling and analysis performed in the period covered by the report and in accordance

with the techniques described in 40 CFR 136, incorporated by reference at

Section 310.107.  For this Section, "significant non-categorical

industrial user" means a significant industrial user that is not subject

to categorical pretreatment standards.  For an industrial user for which USEPA

or the Agency is the Control Authority, as of December 21, 2025 or a

USEPA-approved alternative date (see 40 CFR 127.24(e) or (f)), all reports

submitted in compliance with this Subpart F must be submitted electronically by

the industrial user to the Control Authority or initial recipient, as defined

in Section 310.106(b)(2), in compliance with this Subpart F and Section

310.106.
