RULE 701
AIR POLLUTION EMERGENCY CONTINGENCY ACTIONS
 

(a) Applicability

This rule shall apply to all persons within the jurisdiction of Antelope Valley Air Pollution Control District (AVAPCD) and shall also specify the measures to be taken by the AVAPCD during air pollution episodes.

(b) Purpose

The purpose of this rule is to:
 

  1. define air pollution episode criteria;
  2. provide for episode notification to the public;
  3. recommend precautionary actions to be taken during episodes; and
  4. prevent or reduce the severity of episodes.

(c) Definitions

For the purpose of this rule, the following definitions apply:
 

  1. AIR CONTAMINANT OR AIR POLLUTANT - any discharge, release, or other propagation into the atmosphere and includes, but is not limited to, smoke, charred paper, dust, soot, grime, carbon, fumes, gases, odors, particulate matter, acids or any combination thereof.
  2. DECLARED EPISODE exists whenever the Air Pollution Control Officer determines:
    1. that any of the applicable episode criteria levels specified in this rule have been attained or,
    2. that it is likely that any of the applicable episode criteria levels specified in this rule is imminent to be attained that day.
  3. CHILD DAY CARE FACILITY - a State licensed child day care, pre-school, or after-school program.
  4. EPISODES are the intermediate levels between the National Ambient Air Quality Standard and the Level of Significant Harm for air pollutants at which some pollution abatement or health notification action must be taken. The applicable episode criteria, by pollutant and averaging period established by the Environmental Protection Agency (EPA) and the California Air Pollution Emergency Plan are presented in Attachment 2.
  5. ESSENTIAL PUBLIC SERVICE:
    1. a sewage treatment facility which is publicly owned and operated consistent with an approved regional growth plan;
    2. a prison;
    3. police or fire fighting operations;
    4. schools, hospitals, or ambulance operations;
    5. construction and operation of a landfill gas control or processing facility;
    6. water delivery operations;
    7. public or private utility operations responding to public emergencies or utility outages, excluding routine maintenance, or
    8. public transit;
  6. FORCE MAJEURE NATURAL GAS CURTAILMENT - an interruption in natural gas service due to unforeseeable failure, malfunction, or natural disaster, not resulting from an intentional or negligent act or omission on the part of the owner or operator of a boiler, or a supply restriction resulting from California Public Utility Commission (CPUC) priority allocation system of CPUC Rule 23, such that the daily fuel needs of a boiler cannot be met with the natural gas available.
  7. NEWS MEDIA includes the written press, television, radio, and other mass media of communication such as on-line computer information services.
  8. OUTDOOR ACTIVITY CURTAILMENT ACTIONS - measures, as presented in Attachment 1, to reduce outdoor activities by children during periods when air quality exceeds the Health Advisory Episode level for ozone or the Stage 1 Episode for all other pollutants for which episode criteria are defined.
  9. POLLUTANT STANDARDS INDEX (PSI) - the uniform reporting system established by the U.S. Environmental Protection Agency to make air pollution reports more easily understood by the public. The PSI simplifies information by converting units of air pollution measurement into a uniform scale from 0 to 500.
  10. PREDICTED EPISODE exists whenever the Air Pollution Control Officer determines that it is likely that any of the episode levels specified in this Rule will be reached during the following day.
  11. SCHOOL means public and private educational institutions for children ranging from grades Kindergarten through 12.
  12. UPSET OF PRODUCTION - that the process throughput or production rate is reduced by more than 20 percent of normal daily operations for Stage 2 or Stage 3 Episodes as a direct result of reducing emissions in order to comply with this regulation.
  13. VOLATILE ORGANIC COMPOUND (VOC) Any compound of carbon, excluding carbon monoxide, carbon dioxide, carbonic acid, metallic carbides or carbonates, and ammonium carbonate, which participates in atmospheric photochemical reactions excluding those compounds listed in 40 CFR 51.100(s)(1).
  14. WILDLAND VEGETATIVE MANAGEMENT BURNING means the use of prescribed burning conducted by a public agency, or through a cooperative agreement or contract involving a public agency, to burn land predominantly covered with chaparral, trees, grass or standing brush as defined by Title 17, California Administrative Code, Section 80100.

(d) Measurements

The Air Pollution Control Officer shall maintain air monitoring stations throughout the District so that air quality can be monitored on continuous basis and air pollution episodes can be measured and predicted. Air quality information will be reported daily using the Pollutant Standards Index (PSI).

(e) Facility Requirements
 

  1. The following actions are required for the owner or operator of any facility which has actual emissions of 91 metric tons (100 tons) or more per year of either volatile organic compounds (VOC's), oxides of nitrogen (NOx), or oxides of sulfur (SOx), and are encouraged for all other emitters of these pollutants:
    1. Upon notification of a predicted Stage 2 or Stage 3 episode either from the Air Pollution Control Officer or via the news media, reduce combined emissions for VOC's, NOx, and SOx, by at least 20 percent of normal weekday operations.
    2. Upon notification by the District of the declaration of an air pollution state of emergency by the Governor, take the applicable actions which the Governor requires.
  2. The following actions are required for any facility having 100 or more employees, where employees are defined in Rule 2202:
    1. Upon notification of a predicted Stage 2 or 3 Episode either from Air Pollution Control Officer or via the news media, post at least one sign in a conspicuous place designating the predicted episode stage and requesting ridesharing and telecommuting.
