(Ord. 82-20 § C(7)(F), 1982)

13.12.280 Industrial cost recovery – Significant industrial users’ letter of intent.

Upon written request from the engineer in instances where the city has applied for federal grant money to construct treatment works, each significant industrial user shall send to the city a signed letter of intent to pay that portion of the federal grant amount allocable to the treatment of its wastes as determined by federal regulations. Each such letter shall also include a statement of the industrial user’s intended period of use of the treatment works. (Ord. 82-20 § C(7)(F)(a), 1982)

13.12.290 Industrial cost recovery – System.

A. Each year during the industrial cost recovery period, each industrial user of the treatment works shall pay to the city its share of the total amount of the grant and any grant amended awarded pursuant to this section, divided by the recovery period.

B. Payments shall be made by industrial users no less often than annually. The first payment by an industrial user shall be made not later than one year after such user begins use of the treatment works.

C. An industrial user’s share shall be based on all factors which significantly influence the cost of the treatment works. Factors such as strength, components, volume and delivery flow rate characteristics shall be considered and included to insure a proportional distribution of the federal grant assistance allocable to industrial use to all industrial users of a particular treatment works. At a minimum, an industry’s share shall be proportional based on its flow in relation to the treatment works flow capacity.

D. If there is a substantial change in the strength, components, volume or delivery flow rate characteristics introduced into the treatment works by an industrial user, such user’s share shall be adjusted accordingly.

E. If there is an expansion or upgrading of the treatment works, each existing industrial user’s share shall be adjusted accordingly.

F. An industrial user’s share shall include only that portion of the federal grant assistance allocable to its use or to capacity firmly committed for its use.

G. An industrial user’s share shall not include an interest component. (Ord. 82-20 § C(7)(F)(b), 1982)

13.12.310 Violation – Criteria.

A. A violation of those limitations established under this chapter, federal, state or city pretreatment standards, or specific requirements of an industrial waste discharge permit shall occur, regardless of intent or accident when:

1. The maximum daily allowable concentration is violated under the following circumstances:

a. The arithmetic mean of concentrations for eight consecutive samples collected over intervals of 15 minutes or greater is in excess of the limitation;

b. The concentration of any single sample (whether grab or a sample within a series) exclusive of any fats, oils and greases, exceeds the limitation by a factor of four;

c. The arithmetic mean of the concentration of fats, oils or greases for three grab samples, taken no more frequently than at five-minute intervals, exceeds the limitations;

2. The arithmetic mean of the antilogarithm of the pH values of at least eight consecutive samples taken at intervals of 15 minutes or greater is less than an equivalent pH value of 5.5, or the pH of any single sample is less than 5.0;

3. The temperature limitation is exceeded for any single sample. Each discrete discharge exceeding such limitations, standards or requirements shall constitute a separate violation, or if such discharge is continuous, then each hour of the discharge shall constitute a separate violation.

B. A violation will be considered to have occurred if special reporting requirements established by permit are not complied with.

C. A violation will be considered to have occurred if mass related limitations for specific pollutants have been violated. A violation will be determined utilizing the formula:

(8.34) (millions of gallons discharged)

(concentration pollutant in mg/l)
