§ 28-266. Baseline monitoring reports.

(a)

Within either one hundred eighty (180) days after the effective date of a categorical pretreatment standard, or the final administrative decision on a category determination under 40 CFR 403.6(a)(4), whichever is later, existing categorical industrial users currently discharging to or scheduled to discharge to the POTW shall submit to the manager a report which contains the information listed in paragraph (b), below. At least ninety (90) days prior to commencement of their discharge, new sources, and sources that become categorical users subsequent to the promulgation of an applicable categorical standard, shall submit to the manager a report which contains the information listed in paragraph (b), below. A new source shall report the method of pretreatment it intends to use to meet applicable categorical standards. A new source also shall give estimates of its anticipated flow and quantity of pollutants to be discharged.

(b)

Users described above shall submit the information set forth below:

(1)

Identifying information. The name and address of the facility, including the name of the operator and owner.

(2)

Environmental permits. A list of any environmental control permits held by or for the facility.

(3)

Description of operations. A brief description of the nature, average rate of production, and standard industrial classifications of the operation(s) carried out by such user. This description should include a schematic process diagram which indicates points of discharge to the POTW from the regulated processes.

(4)

Flow measurement. Information showing the measured average daily and maximum daily flow, in gallons per day, to the POTW from regulated process streams and other streams, as necessary, to allow use of the combined wastestream formula set out in 40 CFR 403.6(e).

(5)

Measurement of pollutants.

a.

The categorical pretreatment standards applicable to each regulated process.

b.

The results of sampling and analysis identifying the nature and concentration, and/or mass, where required by the standard or by the manager, of regulated pollutants in the discharge from each regulated process.

c.

Instantaneous, daily maximum, and long-term average concentrations, or mass, where required, shall be reported.

d.

The sample shall be representative of daily operations and shall be analyzed in accordance with procedures set out in section 28-274 of this article. Where the standard requires compliance with a BMP or pollution prevention alternative, the user shall submit documentation as required by the manager or the applicable standard to determine compliance with the standard.

e.

The user shall take a minimum of one (1) representative sample to compile that data necessary to comply with the requirements of this paragraph.

f.

Samples should be taken immediately downstream from pretreatment facilities if such exist or immediately downstream from the regulated process if no pretreatment exists. If other wastewaters are mixed with the regulated wastewater prior to pretreatment the user should measure the flows and concentrations necessary to allow use of the combined wastestream formula in 40 CFR 403.6(e) to evaluate compliance with the pretreatment standards. Where an alternate concentration or mass limit has been calculated in accordance with 40 CFR 403.6(e) this adjusted limit along with supporting data shall be submitted to the control authority;

g.

The manager may allow the submission of a baseline report which utilizes only historical data so long as the data provides information sufficient to determine the need for industrial pretreatment measures.

h.

The baseline report shall indicate the time, date and place of sampling and methods of analysis, and shall certify that such sampling and analysis is representative of normal work cycles and expected pollutant discharges to the POTW.

(6)

Compliance certification. A statement, reviewed by the user's authorized representative as defined in subsection 28-203D. and certified by a qualified professional, indicating whether pretreatment standards are being met on a consistent basis, and, if not, whether additional operation and maintenance (O&M) and/or additional pretreatment is required to meet the pretreatment standards and requirements.

(7)

Compliance schedule. If additional pretreatment and/or O&M will be required to meet the pretreatment standards, the shortest schedule by which the user will provide such additional pretreatment and/or O&M must be provided. The completion date in this schedule shall not be later than the compliance date established for the applicable pretreatment standard. A compliance schedule pursuant to this section must meet the requirements set out in section 28-267 of this article.

(8)

Signature and certification. All baseline monitoring reports must be signed and certified in accordance with section 28-241 of this article by an authorized representative as defined in subsection 28-203D. of this article.
