All significant industrial users shall obtain a significant industrial user permit prior to the commencement of discharge to the POTW. Existing industrial users who are determined by the POTW Director to be significant industrial users shall obtain a significant industrial user permit within 180 days of receiving notification of the POTW Director’s determination. Industrial users who do not fit the significant industrial user criteria may at the discretion of the POTW Director be required to obtain a wastewater discharge permit for non-significant industrial users.
(A) 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 POTW Director a significant industrial user determination. If the POTW Director determines or suspects that the proposed discharge fits the significant industrial user criteria, he or she will require that a significant industrial user permit application be filed.
(B) Significant industrial user permit application. Users required to obtain a significant industrial user permit shall complete and file with the county an application in the form prescribed by the POTW Director, and accompanied by an application fee in the amount prescribed in the schedule of charges and fees. Significant industrial users shall apply for a significant industrial user permit within 90 days after notification of the POTW Director’s determination in division (A) above. The application shall include at a minimum:
(1) Name of the industrial user;
(2) Address of the industrial user;
(3) Standard industrial classification (SIC) codes or expected classification and industrial user category;
(4) Wastewater flow;
(5) Types and concentrations (or mass) of pollutants contained in the discharge;
(6) Major products manufactured or services supplied;
(7) Description of existing on-site pretreatment facilities and practices;
(8) Locations of discharge points;
(9) Raw materials used or stored at the site;
(10) Flow diagram or sewer map for the industrial user;
(11) Number of employees;
(12) Operation and production schedules; and
(13) Description of current and projected waste reduction activities in accordance with G.S. § 143-215.1(g).
(C) Application signatories and certification. All wastewater discharge permit applications and user reports must be signed by the current authorized representative of the user on file with the Control Authority as defined in § 53.002 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.
(D) Application review and evaluation. The POTW Director will evaluate the data furnished by the user and may require additional information.
(1) The POTW Director is authorized to accept applications for the county and shall refer all applications to the POTW staff for review and evaluation.
(2) Within 60 days of receipt the POTW Director shall acknowledge and accept the complete application; or if not complete, shall return the application to the applicant with a statement of what additional information is required.
(E) 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 significant industrial user permit.
(2) If the staff’s tentative determination in division (E)(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) A 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 divisions (E)(1) and (2) above and the general permit conditions of the county into a significant industrial user permit.
(F) Permit supporting documentation. The Control Authority staff shall prepare the following documents for all significant industrial user permits.
(1) An allocation table (AT) listing permit information for all significant industrial users, including but not limited to permit limits, permit effective and expiration dates, and a comparison of total permitted flow and loads with division approved maximum allowable loadings of the POTW, including flow, on forms or in a format approved by the Division. The AT shall be updated as permits are issued or renewed, and as permits are modified where the permitted limits or other AT information is revised.
(2) The basis, or rationale, for the pretreatment limitations, including the following:
(a) Documentation of categorical determination, including documentation of any calculations used in applying categorical pretreatment standards; and
(b) Documentation of the rationale of any parameters for which has been waived under 40 C.F.R. Part 403.12(e)(2).
(G) Final action on significant industrial user permit applications.
(1) The POTW Director shall take final action on all applications not later than 90 days following receipt of a complete application.
(2) The POTW Director is authorized to:
(a) Issue a significant industrial user permit containing such conditions as are necessary to effectuate the purposes of this chapter and G.S. § 143-215.1;

(c) Modify any permit upon not less than 60 days’ notice and pursuant to division (I) of this section;
(d) Revoke any permit pursuant to § 53.106;
(e) Suspend a permit pursuant to § 53.106; and
(f) Deny a permit application when in the opinion of the POTW Director such discharge may cause or contribute to pass- through or interference of the wastewater treatment plant, or where necessary to effectuate the purposes of G.S. § 143-215.1.
(H) Permit modification.
(1) Modifications of permits shall be subject to the same procedural requirements as the issuance of permits except as listed below. Any changes or new conditions in the permit shall include a reasonable time schedule for compliance:
(a) Changes in the ownership of the discharge when no other change in the permit is indicated;
(b) A single modification of any compliance schedule not in excess of four months; and
(c) Modification of compliance schedules (construction schedules) in permits for new sources where the new source will not begin to discharge until control facilities are operational.
(2) Within nine months of the promulgation of a national categorical pretreatment standard, the wastewater discharge permit of users subject to such standards shall be revised to require compliance with such standard within the time frame prescribed by such standard. Where a user, subject to a national categorical pretreatment standard, has not previously submitted an application for a wastewater discharge permit as required by this section, the user shall apply for a wastewater discharge permit within 180 days after the promulgation of the applicable national categorical pretreatment standard.
