8-28-114 Limited Exemption, Small Refineries: Section 8-28-304.2 shall not apply to petroleum refineries processing less than 20,000 barrels per stream day of crude, unless the District’s evaluation of the Process Hazards Analysis in Section 8-28-303.1 determines that it is cost-effective and technologically feasible for the refinery to control the pressure relief devices.

(Adopted December 17, 1997)

8-28-200 DEFINITIONS

Chemical plants may include, but are not limited to the manufacture of: industrial inorganic and organic chemicals; plastic and synthetic resins, synthetic rubber, synthetic and other man-made fibers; drugs; soap, detergents and cleaning preparations, perfumes, cosmetics and other toilet preparations; paints, varnishes, lacquers, enamels and allied products; agricultural chemicals; safflower and sunflower oil extracts; re-refining, not including petroleum refineries.

(Adopted July 20, 1983, amended December 17, 1997)

8-28-202 Pressure Relief Valve: The automatic pressure-relieving device actuated by the static pressure upstream of the valve.

8-28-207 Modified Source: The same definition contained in District Regulation 2-2-223.

(Adopted December 17, 1997)

 

8-28-208 Parallel Service: Additional pressure relief devices which protect a common piece or pieces of equipment. These additional pressure relief devices may be installed as spares to facilitate maintenance or because the design relieving capacity cannot be obtained with a single pressure relieving device. The pressure relieving devices do not need to have the same pressure setting to be considered parallel.

(Adopted December 17, 1997)

8-28-209 Petroleum Refinery: Any facility that processes products as defined in Standard Industrial Classification Manual as Industry No. 2911, Petroleum Refining.

(Adopted December 17, 1997)

8-28-210 Pressure Relief Device: The automatic pressure-relieving device for discharges of organic compounds which prevents safety hazards, prevents pressures from exceeding the maximum allowable working pressure of the operating process equipment or prevents equipment damage. Such devices include, but are not limited to, pressure relief valves, emergency de-pressuring vents or rupture disks.

(Adopted December 17, 1997)

 

8-28-211 Prevention Measure: A reliable component, system, or program that will prevent a Release Event. Examples of prevention measures include, but are not limited to:

  1. flow, temperature, level and pressure indicators with interlocks, deadman switches, monitors, or automatic actuators,
  2. documented and verified routine inspection and maintenance programs,
  3. inherent safer designs,
  4. deluge systems.

Operator training and documented and verified routine inspection and maintenance programs may count as only one of the 3 Prevention Measures required by Section 8-28-302.2, 8-28-303.2, and 8-28-304.1. A component, system or program with a high probability for failure shall not be considered a Prevention Measure.

(Adopted December 17, 1997)

8-28-212 Process Hazards Analysis (PHA): A PHA is an organized effort to identify and analyze the significance of hazardous scenarios associated with a process or activity. For the purposes of this rule, PHA’s are used to pinpoint weaknesses in the design and operation of facilities that could lead to a Release Event and to provide the facility with information to aid in making decisions for preventing such events.

(Adopted December 17, 1997)

8-28-213 Qualified Person: An APCO approved person who is qualified to attest to the validity of the Prevention Measures Procedures and who is a registered professional engineer in the State of California with expertise in chemical, mechanical or safety engineering.

(Adopted December 17, 1997)

8-28-214 Release Event: Any release of organic or inorganic pollutant greater than 10 pounds resulting from a pressure relieving device, subject to this Rule, opening to the atmosphere.
