Authority to Inspect. During normal and reasonable hours of operation, any Authorized Enforcement Official shall have the authority to make an inspection to enforce the provisions of this chapter, and to ascertain whether the purposes of this chapter are being met. An inspection may be made after the Authorized Enforcement Official has presented proper credentials and the owner and/or occupant authorizes entry. If the Authorized Enforcement Official is unable to locate the owner or other persons having charge or control of the Premises, or the owner and/or occupant refuses the request for entry, the City is hereby empowered to seek assistance from any court of competent jurisdiction in obtaining entry and to recover the costs of seeking such assistance from the owner(s) and/or occupant(s) that refused the request for entry.

After obtaining legal entry, the Authorized Enforcement Official may:

(1)

Inspect the Premises.

(2)

Carry out any sampling activities necessary to enforce this chapter, including taking samples from the property of any Person or from any vehicle that the Authorized Enforcement Official reasonably believes is currently, or has in the past, caused or contributed to causing an Illegal Discharge to the Storm Water Conveyance System. Upon request, split samples shall be given to the Person from whose property or vehicle the samples were obtained.

(3)

Stop and inspect any vehicle reasonably suspected of causing or contributing to an Illegal Discharge to the Storm Water Conveyance System when accompanied by a law enforcement officer in a clearly marked vehicle.

(4)

Conduct tests, analyses, and evaluations to determine whether a discharge into the Storm Water Conveyance System is an Illegal Discharge or whether the requirements of this Chapter are met.

(5)

Photograph any effluent stream, material or waste, material or waste container, container label, vehicle, waste treatment process, waste disposal site, or condition contributing to Storm Water pollution and constituting a violation of this Chapter found during an inspection.

(6)

Review and obtain a copy of the Storm Water Pollution Prevention Plan prepared by an owner and/or occupant or Facility operator, if such a plan has been required.

(7)

Require the owner and/or occupant or Facility operator to retain evidence for a period not to exceed 30 days.

(8)

Review and obtain copies of all Storm Water monitoring data compiled by the owner and/or occupant or Facility operator, if such monitoring is required.

Routine or area inspections shall be based upon such reasonable selection processes as may be deemed necessary to carry out the objectives of this chapter, including but not limited to, random sampling and/or sampling in areas with evidence of Storm Water pollution, Illegal Discharges, or similar factors.

(b)

Inspection Procedures. During the inspection, the Authorized Enforcement Official shall comply with all reasonable security, safety, and sanitation measures. In addition, the Authorized Enforcement Official shall comply with reasonable precautionary measures specified by the owner and/or occupant or Facility operator.

At the conclusion of the inspection, and prior to leaving the site, the Authorized Enforcement Official will review with the owner and/or occupant or Facility operator each of the violations noted by the Authorized Enforcement Official and the corrective actions needed, if any. A report listing any violation found during the inspection shall be prepared by the Authorized Enforcement Official and shall be kept on file in the enforcement agency. A copy of the report shall be provided to the owner and/or occupant or Facility operator, or left at the Premises if neither the owner, occupant, nor Facility operator is available. If corrections are needed, the owner and/or occupant or Facility operator shall implement a plan of corrective action based on a written plan of correction, submitted to the enforcement agency, which states the actions to be taken and the expected dates of completion. Failure to implement the plan of correction constitutes a violation of this chapter.

(c)

Authority to Sample and Establish Sampling Devices. The City shall have the right to establish on any property such devices as are necessary to conduct sampling or metering operations. During all inspections as provided herein, the Authorized Enforcement Official may take any samples deemed necessary to aid in the pursuit of the inquiry or in the recordation of the activities on.

Notification of Spills. As soon as any Person who is responsible for emergency response for, or in charge of, any Premises or Facility has knowledge of any confirmed or unconfirmed significant release of materials, Pollutants or waste which may result in Pollutants or Illegal Discharges entering the Storm Water Conveyance System, such Person shall take all necessary steps to ensure the containment and minimize the damages of such release, provided that such steps do not violate applicable health and safety regulations and/or Facility hazardous materials handling procedures and policies. Such Person shall notify the Environmental Health Services' Hazardous Materials Management Division of the County of San Diego Department of Health Services, together with any other appropriate or applicable agency, of the occurrence within 24 hours of the incident's occurrence.

(e)

Requirement to Test, Monitor or Mitigate.

(1)

The Director may require that any Person engaged in any activity and/or owning or operating any Facility which may cause or contribute to Storm Water pollution, or Illegal Discharges to the Storm Water Conveyance System, undertake such monitoring activities, including physical and chemical monitoring and/or analyses, and furnish reports as the Director may specify if the person, or Facility owner, or operator fails to eliminate Illegal Discharges after receiving a written notice by the enforcement agency, or the Director has documented repeated violations of this chapter which may have contributed to Storm Water pollution. Specific monitoring requirements shall bear a reasonable relationship to the types of Pollutants that may be generated by the person's activities or the Facility's operations. If the Director has evidence that a Pollutant is originating from a specific Premises, then the Director may require monitoring for that Pollutant regardless of whether the Pollutant may be generated by routine activities or operations. The burden, including costs, of these activities, analyses and reports shall bear a reasonable relationship to the need for the monitoring, analyses and reports and the benefits to be obtained. The recipient of such request shall undertake and provide the monitoring, analyses and/or reports requested.

The Director, in cooperation with local wastewater programs, may require a Person, or Facility owner or operator, to install or implement Storm Water pollution reduction or control measures, including but not limited to, process modification to reduce the generation of Pollutants or a pretreatment program approved by the Regional Water Quality Control Board and/or the City if:

a.

The Person, or Facility owner or operator, fails to eliminate Illegal Discharges after receiving a written notice by the enforcement agency; or

b.

The Person, or Facility owner or operator, fails to implement a Storm Water Pollution Prevention Plan, as required by the enforcement agency; or

c.

The enforcement agency has documented repeated violations of this Chapter which may have contributed to Storm Water pollution.

(4)

A Person, or Facility owner or operator, may discontinue sampling and analyses required pursuant to this chapter if Pollutants are not detected in significant quantities after two consecutive sampling events. If testing, monitoring, or mitigation required pursuant to this chapter are deemed no longer necessary by the Director, then any or all of the above requirements will be discontinued.

(5)

A Storm Water monitoring program prepared and implemented pursuant to any NPDES Permit shall meet the requirements of a monitoring program for the purposes of this Chapter.
