Carson Zoning Code · 2026-06 edition · updated 2026-07-25 · Carson

If the site is within one thousand five hundred (1,500) feet of any prohibited zoning as listed in Table 1-1, at all times the operator shall comply with the provisions of an air monitoring plan that has been approved by the Petroleum Administrator. During all well operations, including but not limited to drilling, redrilling and workover operations, the operator shall continuously monitor for hydrogen sulfide, in a manner that allows for detection of pollutants from all wind directions, as approved by the Petroleum Administrator. Total hydrocarbon vapors shall be monitored at drilling, workover and processing plant areas as specified in the approved plan. Such monitors shall provide automatic alarms that are triggered by the detection of hydrogen sulfide or total hydrocarbon vapors. The alarms shall be audible and/or visible to the person operating the equipment. Actions to be taken shall be as follows when specified alarm levels are reached:

  • A. At a hydrogen sulfide concentration of equal to or greater than five (5) parts per million but less than ten (10) parts per million, the operator shall immediately investigate the source of the hydrogen sulfide emissions and take prompt corrective action to eliminate the source. The corrective action taken shall be documented in the drilling or workover log. If the concentration is not reduced to less than five (5) parts per million within four (4) hours of the first occurrence of such concentration, the operator shall shut down the drilling or workover operations and equipment in a safe and controlled manner, until the source of the hydrogen sulfide emissions has been eliminated, unless shutdown creates a health and safety hazard.

  • B. At a hydrogen sulfide concentration equal to or greater than ten (10) parts per million, the operator shall promptly shut down the drilling or workover operations and equipment in a safe and controlled manner until the source of the hydrogen sulfide emissions has been eliminated, unless shutdown creates a health and safety hazard. The corrective action taken shall be documented in the drilling or workover log. When an alarm is received, the operator shall promptly notify the Los Angeles County Fire Department, the Petroleum Administrator, and the SCAQMD.

  • C. At a total hydrocarbon concentration equal to or greater than five hundred (500) parts per million but less than one thousand (1,000) parts per million, the operator shall immediately investigate

the source of the hydrocarbon emissions and take prompt corrective action to eliminate the source. The corrective action taken shall be documented in the drilling log for drilling or workover and in the log for the oil and gas site. If the concentration is not reduced to less than five hundred (500) parts per million within four (4) hours of the first occurrence of such concentration, the operator shall shut down the drilling or workover or site operations in a safe and controlled manner, until the source of the hydrocarbon emissions has been eliminated, unless shutdown creates a health and safety hazard.

e oil and gas site. If the concentration is not reduced to less than five hundred (500) parts per million within four (4) hours of the first occurrence of such concentration, the operator shall shut down the drilling or workover or site operations in a safe and controlled manner, until the source of the hydrocarbon emissions has been eliminated, unless shutdown creates a health and safety hazard.

  • D. At a total hydrocarbon concentration equal to or greater than one thousand (1,000) parts per million, the operator shall promptly shut down the drilling or workover or operations in a safe and controlled manner, until the source of the hydrocarbon emissions has been eliminated, unless shutdown creates a health and safety hazard. The corrective action taken shall be documented in the drilling log for drilling or workover and in the log. When an alarm is received, the operator shall promptly notify the Los Angeles County Fire Department Health Hazardous Materials Division, and the SCAQMD.

  • E. The Petroleum Administrator may also require additional monitoring at the closest residential receptor periodically for hydrogen sulfide, hydrocarbons or toxic air contaminants. All the monitoring equipment shall keep a record of the levels of total hydrocarbons and hydrogen sulfide detected at each of the monitors, which shall be retained for at least five (5) years. The operator shall, on a quarterly basis, provide a summary of all monitoring events where the hydrogen sulfide concentration was at five (5) parts per million or higher and the total hydrocarbon concentration was at five hundred (500) parts per million or higher to the Fire Chief of the Los Angeles County Fire Department. At the request of the Fire Chief, the operator shall make available the retained records from the monitoring equipment.
