13.11.050 Enforcement.

The city of Roslyn has determined that commercial customers served by the sewer system who have not complied with some or all of the above-referenced requirements create additional maintenance, operation, repair, and replacement costs of the various parts of the sewer system. Therefore, commercial customers served by the city of Roslyn’s sewer system that fail to comply with the city of Roslyn’s FOG management program will be assessed a service rate surcharge in accordance with the following procedures:

A. Upon discovery of a failure to comply with the terms and conditions of the city of Roslyn’s FOG management program, the public works director’s designee shall notify the commercial establishment and the property owner (if different) in writing of the violation and give the commercial establishment 30 days to comply.

B. If the commercial establishment fails to correct the violation within 30 days, then the following monthly service rate surcharge(s) shall be assessed against the commercial customer receiving service from the city of Roslyn:

1. Failure to adopt a management plan – $50.00.

2. Failure to allow inspection – $50.00.

3. Failure to install required equipment or process – $50.00.

4. Failure to meet discharge standards – $100.00.

5. Failure to maintain records – $50.00.

The above-referenced service rate surcharges shall be subject to collection and enforcement as any other rates and charges of the city of Roslyn.

C. For each and every subsequent month that a commercial establishment is in violation of the city of Roslyn’s FOG management program, the applicable service rate surcharge(s) shall double in amount until completion of the third month of violation. At that time, the city of Roslyn may terminate sewer service to the commercial customer until corrective action has been taken and the sewer service surcharges paid in full, or take such other actions as the city of Roslyn deems appropriate to obtain compliance with the city of Roslyn’s FOG management program and to collect the sewer service surcharges.

D. In the event that the city cleans a sewer main blocked by FOG originating from a commercial establishment, the commercial establishment shall reimburse the city for those costs. [Ord. 1147 § 1, 2018; Ord. 1136 § 1, 2017].
