15.14.042 Wastewater discharge permit – Application contents

15.14.042 Wastewater discharge permit – Application contents.

A. Application for wastewater discharge permits shall be made to the director, in writing, and shall include the information required in subsection (C) of this section.

B. Applicants that are subject to categorical pretreatment standards shall comply with all baseline reporting requirements contained in BMC 15.14.050 prior to discharge permit issuance or commencement of discharge, whichever comes first, unless the specific conditions of a discharge permit establish an alternate deadline.

C. Wastewater discharge permit applications shall include the following information and shall be submitted in a form approved by the director:

1. Identifying Information. The applicant shall submit the name and address of the facility including the name of the operator and owners.

2. Permits. The applicant shall submit a list of any environmental control permits held by or for the facility.

3. Description of Operations. The applicant shall submit a brief description of the nature, average rate of production, and the NAICS of the operation(s) carried out by such user, including a list of all raw materials and chemicals used or stored at the facility that are, or could accidentally or intentionally be, discharged to the POTW; number and type of employees; hours of operation; each product produced by type, amount, process or processes, and rate of production; type and amount of raw materials processed (average and maximum per day) and the time and duration of discharges. This description must also include a schematic process diagram that indicates points of discharge to the POTW from the regulated or manufacturing processes. Submittals must also include site plans, floor plans, mechanical and plumbing plans and details necessary to show all sewers, sewer connections, inspection manholes, sampling stations and appurtenances by size, location, and elevation.

a. Applicants that are subject to categorical pretreatment standards shall submit information showing the measured average daily flow and maximum daily flow, in gallons per day, to the POTW from each of the following:

i. Regulated or manufacturing process streams; and

ii. Other streams as necessary to allow use of the combined waste stream formula of 40 CFR 403.6(e).

b. Applicants that are not subject to categorical pretreatment standards shall submit information showing the measured average daily flow and maximum daily flow, in gallons per day, to the POTW from each of the following:

i. Total process flow, treatment plant flow, total plant flow, or individual manufacturing process flow as required by the director. The director may allow verifiable estimates of these flows where justified by cost or feasibility considerations.

c. Applicants who have not yet commenced operations shall submit estimates of the flow measurements required under this subsection (C)(4).

a. Applicants that are subject to categorical pretreatment standards shall provide the following information:

i. The applicant shall identify the applicable pretreatment standards for each regulated or manufacturing process. The director may require additional sampling to characterize the waste stream;

ii. In addition, the applicant shall submit the results of sampling and analysis identifying the nature and concentration (or mass) where required by the categorical pretreatment standard or as required by the director of regulated pollutants (including standards contained in BMC 15.14.021 through 15.14.023, as appropriate) in the discharge from each regulated or manufacturing process. Both daily maximum and average concentration (or mass, where required) shall be reported. The sample shall be representative of daily operations and shall conform to sampling and analytical procedures outlined in Article VI of this chapter. Screening for certain VOCs may be required by the director to prevent the release of gases and fumes into the collection system to protect worker safety;

iii. The applicant shall take a minimum of one representative sample taken downstream from pretreatment facilities, if such exist, or downstream of the regulated process(es) to compile that data necessary to comply with the requirements of this subsection; and

iv. Where an alternate concentration or mass limit has been calculated in accordance with 40 CFR 403.6(e) for a categorical user covered by a categorical pretreatment standard, this adjusted limit along with supporting data shall be submitted as part of the application.

b. Applicants that are not subject to categorical pretreatment standards shall provide the following information:

i. The applicant shall identify the applicable pretreatment standards for its wastewater discharge. The director may require additional sampling to characterize the waste stream;

ii. The applicant shall submit the results of sampling and analysis identifying the nature and concentration (or mass where required by the director) of regulated pollutants contained in BMC 15.14.021 through 15.14.023, as appropriate in the discharge. Both daily maximum and average concentration (or mass, where required) shall be reported. The sample shall be representative of daily operations and shall conform to sampling and analytical procedures outlined in Article VI of this chapter;

iii. The applicant shall take a minimum of one representative sample to compile that data necessary to comply with the requirements of this subsection;

iv. Where the director developed alternate concentration or mass limits because of dilution this adjusted limit along with supporting data shall be submitted as part of the application;

v. Screening for certain VOCs may be required by the director to prevent the release of gases and fumes into the collection system to protect worker safety.

c. Applicants who have not commenced operations shall submit estimates of the pollutant measurements required under this subsection (C)(5).

6. Certification. A statement, reviewed by an authorized representative of the applicant and certified as outlined in BMC 15.14.043, indicating whether applicable pretreatment standards are being met on a consistent basis, and, if not, whether additional pretreatment and/or O&M are required for the applicant to meet applicable pretreatment standards. Applicants who have not yet commenced operations shall identify the pretreatment and/or O&M that it intends to use to meet applicable pretreatment standards.

7. Compliance Schedule. If additional pretreatment and/or O&M are required to meet applicable pretreatment standards, the applicant shall propose the shortest schedule by which the applicant will provide such additional pretreatment and/or O&M. The proposed schedule shall conform to the requirements of BMC 15.14.024 and 15.14.053.

8. Any other information as may be deemed necessary by the director to evaluate the application. Incomplete or inaccurate applications will not be processed and will be returned to the applicant for supplement and/or revision.

9. Information required to establish any periodic sampling and reporting waiver requested pursuant to BMC 15.14.052(E). [Ord. 2020-07-016 § 1; Ord. 2019-11-032 § 1].
