13.90.230 Wastewater discharge permit application contents.

(1) All users required to obtain a wastewater discharge permit must apply using the form provided by the Public Works Director. Users eligible for coverage under a general permit may request such coverage using an industry-specific form if one has been developed (see PMC 13.90.250). Users must supply the Public Works Director the following information as part of the permit application if relevant to the user’s operation unless waived by the Public Works Director:

(i) The name and physical address of the facility, the names of the operator/facility manager and owner, and the name and address of the point of contact; and

(ii) A description of activities, facilities, and plant production processes on the premises;

(b) A list of any environmental control permits held by or for the facility;

(i) A brief description of the operations, average rate of production, and industrial classification (SIC or NAICS codes) of the operation(s) conducted on site;

(ii) The number and type of employees, and proposed or actual hours of operation;

(iii) The type, amount, rate of production, and process used for each product produced;

(iv) The type and amount of raw materials used (average and maximum rates);

(v) The raw materials and chemicals to be routinely stored at the facility (including products in rail cars and tank trucks located on site);

(vi) The types of wastes generated on a routine and periodic basis;

(vii) The times and durations when wastes will be discharged;

(viii) A schematic process diagram showing each process step, wastestream, treatment step, internal recycle, and point of discharge to the POTW. This diagram should identify which streams are subject to categorical standards;

(ix) Site plans, floor plans, mechanical and plumbing plans, and details to show all sewers, floor drains, and appurtenances by size, location, and elevation, and all points of discharge;

(x) The sampling locations and provisions for monitoring discharges; and

(xi) Indicate whether plans for wastewater facilities under Chapter 173-240 WAC have been developed, and their approval status (engineering report, plans and specifications, and an O&M manual).

(d) Flow Data. The average daily and maximum daily flow, in gallons per day, to the POTW from each wastestream; information shall be complete enough to allow use of the CWF per PMC 13.90.060(3) and 40 CFR § 403.6(e) where applicable.

(i) The categorical pretreatment standards applicable to each regulated process;

(ii) The results of sampling and analysis identifying the nature and concentration (and mass where required by the standard or the Public Works Director) of regulated pollutants in the discharge from each regulated process; and

(iii) The estimated peak instantaneous, maximum daily, and long-term average discharge concentrations (and mass) based on the sampling results.

(f) Sampling data to show samples are:

(i) Representative of daily operations;

(ii) Taken just downstream from pretreatment facilities, if such exist, or just downstream of the regulated processes if no pretreatment exists;

(iii) Collected as required by PMC 13.90.440; and

(iv) Analyzed according to PMC 13.90.450.

(g) Information confirming BMPs. Where standards specify BMPs or pollution prevention alternative, the user must include the information needed by the Public Works Director or the applicable standard to determine whether BMPs are (or will be) implemented.

(h) Any requests for a monitoring waiver (or a renewal of an approved monitoring waiver) for a pollutant neither present nor expected to be present in the discharge must include new sampling showing (continued) absence of the pollutant in the raw wastewater and satisfying PMC 13.90.380(2).

(i) Any request to be covered by a general permit shall satisfy PMC 13.90.240.

(j) Any other information deemed necessary by the Public Works Director to evaluate the situation and prepare a discharge permit.

(2) Incomplete or inaccurate applications will not be processed and will be returned to the user for revision. The Public Works Director shall be held harmless for delays caused by returned applications. [Ord. 4169 § 1, 2014; Code 1970 § 13.62.040(E).]
