All users and significant industrial users whose six-month average exceeds one (1) or more of these domestic waste pollutant concentrations must request an industrial user permit in accordance with Section 79 below.

(Res. of 6-9-03(2))

Section 79. - Permit application and issuance.

A.

Significant industrial users. All significant industrial users must apply for, and obtain, an industrial user permit from the director prior to discharging wastewater to a POTW. Such significant industrial users must pay a permit development fee as outlined in Section 125. Existing industrial users who are determined by the director to be significant industrial users shall obtain an industrial user permit within one hundred eighty (180) days of receiving notification of the director's determination. Industrial users who do not fit the significant industrial user criteria may at the discretion of the director be required to obtain a wastewater discharge permit for commercial users.

B.

Significant industrial user determination. All persons proposing to discharge non-domestic wastewater, or proposing to change the volume or characteristics of an existing discharge of non-domestic wastewater shall request from the director a significant industrial user determination. If the director determines or suspects that the proposed discharge fits the significant industrial user criteria he will require that an industrial user permit application be filed.

C.

Other users. Users who discharge wastewater that exceeds the domestic waste concentrations as specified in Section 78 shall request an industrial user discharge determination from the director by filing a permit application. A user must submit a permit application and all supporting information within sixty (60) days of either exceeding the domestic average, or receipt of the director's request, whichever comes first. Upon receipt of the permit application, the director will determine if a permit is required and, if so, will develop a permit under subsection G. below. For users who exceed the domestic waste values as set forth in Section 78 the director will determine if the exceedance is so significant as to require a permit.

D.

Industrial user permit application. Users required to obtain an industrial user permit shall complete and file with the commission, an application in the form prescribed by the director. Significant industrial users shall apply for an industrial user permit within ninety (90) days after notification of the director's determination in subsection (A) above. The application shall include at a minimum the information required by 15A NCAC 02H 0.0916(c)(1)(A—M). In support of the application the user shall submit any other information deemed necessary by the director to evaluate the permit application. This may include reporting requirements under 40 CFR 403.12(b) and Section 86.

E.

Application signatories and certification. All permit applications and user reports must be signed by the current authorized representative of the user on file with the director as defined in Section 2 and contain the following certification statement:

"I certify under penalty of law that this document and all attachments were prepared under my direction or supervision in accordance with a system designed to assure that qualified personnel properly gather and evaluate the information submitted. Based on my inquiry of the person or persons who manage the system, or those persons directly responsible for gathering the information, the information submitted is, to the best of my knowledge and belief, true, accurate, and complete. I am aware that there are significant penalties for submitting false information, including the possibility of fine and imprisonment for knowing violations."

F.

Permit development. Significant industrial users, and other users who the director determines must obtain a permit after review of their permit application, shall submit all other information the director determines is necessary for development of a permit. Users who do not fit the significant industrial user criteria may, at the discretion of the director, be required to obtain a commercial wastewater discharge permit. Commercial users shall pay a permit development fee as required in Section 125 C.

G.

Tentative determination and draft permit.

1.

The POTW staff shall conduct a review of the application and an on-site inspection of the significant industrial user, including any pretreatment facilities, and shall prepare a written evaluation and tentative determination to issue or deny the industrial user permit.

2.

If the staff's tentative determination in paragraph 1. above is to issue the permit, the following additional determinations shall be made in writing:

a.

Proposed discharge limitations for those pollutants proposed to be limited;

b.

Proposed schedule of compliance, including interim dates and requirements, for meeting the proposed limitations; and

c.

A brief description of any other proposed special conditions which will have significant impact upon the discharge described in the application.

3.

The staff shall organize the determinations made pursuant to paragraphs 1. and 2. above and the commission's general permit conditions into an industrial user permit.

H.

Permit synopsis. A fact sheet providing a brief synopsis of the application shall be prepared by the POTW staff for submission to the applicant and the approval authority and shall be made available to the public upon request. The contents of such fact sheets shall include at least the following information:
