<ns0:Title> An act to amend Section 42705.6 of the Health and Safety Code, relating to air resources. </ns0:Title>
<ns0:RelatingClause>air resources</ns0:RelatingClause>
<ns0:GeneralSubject>
<ns0:Subject>Air resources: refinery-related community air monitoring system.</ns0:Subject>
</ns0:GeneralSubject>
<ns0:DigestText>
<html:p>Existing law requires a refinery-related community air monitoring system to be installed near each refinery, as provided, and requires the monitoring system to include equipment capable of measuring compounds emitted to the atmosphere from refinery processes. Existing law requires owners or operators of petroleum refineries to develop, install, operate, and maintain a fence-line monitoring system in accordance with guidance developed by the appropriate regional air pollution control district or regional air quality management district.</html:p>
<html:p>This bill would require guidance adopted to implement the fence-line monitoring system
to include a process for a petroleum refinery to provide substantial evidence to the appropriate air district to exclude a pollutant for monitoring in a fence-line monitoring system and would authorize the air district to exclude a pollutant for monitoring at a petroleum refinery fence-line monitoring system if the air district determines that substantial evidence supports certain considerations. Because the bill would require air districts to revise their guidance related to the fence-line monitoring system, this bill would impose a state-mandated local program.</html:p>
<html:p>The California Constitution requires the state to reimburse local agencies and school districts for certain costs mandated by the state. Statutory provisions establish procedures for making that reimbursement.</html:p>
<html:p>This bill would provide that no reimbursement is required by this act for a specified reason.</html:p>

(a)
<html:span class="EnSpace"/>
For purposes of this section, the following definitions apply:
</html:p>
<html:p>
(1)
<html:span class="EnSpace"/>
“Refinery-related community air monitoring system” means equipment that measures and records air pollutant concentrations in the ambient air at or near sensitive receptor locations near a petroleum refinery and that may be useful for estimating associated pollutant exposures and health risks and in determining trends in air pollutant levels over time.
</html:p>
<html:p>
(2)
<html:span class="EnSpace"/>
“Fence-line monitoring system” means equipment that measures and records air pollutant concentrations at or adjacent to a petroleum refinery and that may be useful for detecting or estimating the
quantity of fugitive emissions, gas leaks, and other air emissions from the refinery.
</html:p>
<html:p>
(b)
<html:span class="EnSpace"/>
Notwithstanding Section 42708, and on or before January 1, 2020, a refinery-related community air monitoring system shall be installed near each refinery that is consistent with the requirements and guidance applicable to the siting of air quality monitors as established by the federal Environmental Protection Agency and that meets all of the following requirements:
</html:p>
<html:p>
(1)
<html:span class="EnSpace"/>
A district shall design, develop, install, operate, and maintain the refinery-related community air monitoring system, which shall be operated and maintained in accordance with guidance from the appropriate district. A district may contract with a third party to implement this paragraph.
</html:p>
<html:p>
(2)
<html:span class="EnSpace"/>
The refinery-related community air monitoring system shall include equipment capable of measuring compounds emitted to the atmosphere from refinery processes, as determined by the appropriate district.
</html:p>
<html:p>
(c)
<html:span class="EnSpace"/>
(1)
<html:span class="EnSpace"/>
On or before January 1, 2020, the owner or operator of a petroleum refinery shall develop, install, operate, and maintain a fence-line monitoring system in accordance with guidance developed by the appropriate district.
</html:p>
<html:p>
(2)
<html:span class="EnSpace"/>
Guidance adopted pursuant to this section shall
include a process for a petroleum refinery to provide substantial evidence to the appropriate district to exclude a pollutant for monitoring in a fence-line monitoring system.
</html:p>
<html:p>
(3)
<html:span class="EnSpace"/>
Recognizing that emissions vary among refineries, a district may exclude a pollutant for monitoring at a petroleum refinery fence-line monitoring system if the district determines that substantial evidence supports any of the following:
</html:p>
<html:p>
(A)
<html:span class="EnSpace"/>
The pollutant would not be released through routine and nonroutine operations, activities, and processes of the petroleum refinery.
</html:p>
<html:p>
(B)
<html:span class="EnSpace"/>
Realtime monitoring of the pollutant is technologically infeasible.
</html:p>
<html:p>
(C)
<html:span class="EnSpace"/>
Technical justifications deemed appropriate by the district.
</html:p>
<html:p>
(d)
<html:span class="EnSpace"/>
The district and the owner or operator of a petroleum refinery shall collect real-time data from the refinery-related community air monitoring system and the fence-line monitoring system and shall maintain records of that data. To the extent feasible, the data generated by these systems shall be provided to the public as quickly as possible in a publicly accessible format.
</html:p>
<html:p>
(e)
<html:span class="EnSpace"/>
Guidance developed by a district pursuant to this section shall take into account technological capabilities and incorporate input from affected
parties and, to the extent feasible, shall be informed by refinery-related guidance in the monitoring plan prepared pursuant to subdivision (b) of Section 42705.5.
</html:p>
<html:p>
(f)
<html:span class="EnSpace"/>
(1)
<html:span class="EnSpace"/>
Except as provided in paragraph (2), the owner or operator of a petroleum refinery shall be responsible for the costs associated with implementing this section.
</html:p>
<html:p>
(2)
<html:span class="EnSpace"/>
To the extent a refinery-related community air monitoring system is intentionally used by a district to monitor emissions from sources under its jurisdiction other than a petroleum refinery, the district shall ensure the costs of the system are shared in a reasonably equitable manner.
