## Ozone Emergency Episode Plan

PREPARED IN COMPLIANCE WITH THE FEDERAL CLEAN AIR ACT

Adopted June 11, 2015Ozone Emergency Episode Plan Placer County Air Pollution Control District Adopted June 11, 2015 Page 1 of 11
Purpose This Ozone Emergency Episode Plan provide s the basis for taking action to prevent ambient ozone concentrations from reaching levels which could endanger public health, or to abate such concentrations should they occu r. It identifies criteria for the four levels of emergency episodes, components for public announcements whenever an episode has been identified, and specifies em ission control strategies to be taken with each episode.

Legal Authority The Federal Clean Air Act (CAA) 1 gives the U.S. Environmental Protection Agency (U.S. EPA) the legal authority to halt the emission of air pollutants causing or contributing to the injury of the public or their welfare. Th e U.S. EPA is further authorized to either bring a lawsuit in federal cour t or, if such civil action cannot assure prompt protection of public health or welfare, to issue such orders as may be necessary to protect public health, welfare, or the environment. The authority granted to the U.S. EPA Administrator is
vested in the California Air Resources Bo ard (ARB) and the air districts under the California Health & Safety Code (H&SC) 2 . This section of Calif ornia law applies to a range of emissions violations and imposes pe nalties that are equivalent to or exceed federal penalties for comparable violations . These penalties include the imposition of fines and/or imprisonment.

Under the authority of the H&SC, the ARB is responsible for controlling emissions from mobile sources, while districts are responsib le for controlling emissions from non-mobile
sources. H&SC Section 41700 states that sources are prohibited from emitting any pollutant(s) that can cause injury, detriment, nuisance, or annoyance to the public, or that endanger the comfort, repose, health, or safe ty of the public. Furthermore, H&SC Section 42450, et seq., gives districts sp ecific authority to abate em issions from any source violating H&SC Section 41700 or any other orde r, rule, or regulation that prohibits or limits the discharge of pollutants, consistent with applicable notice and hearing requirements. Under H&SC Section 41509, the ARB or other local agency rules cannot infringe upon a district’s authority to de clare, prohibit, or abate a nuisance, and California’s Attorney General is authorized to enjoin any pollution or nuisance, either on his or her own, or by request.

In addition to the authority under H&SC, the lo cal air districts can work with the local governing body of a city, county, or city and county, pursuant to the California Emergency Services Act 3 , to proclaim a local emergenc y when there are conditions of disaster or of extreme peril to the safety of persons and property within the territorial

limits of a city, county, or both a city and county, caused by such conditions as air pollution 4 . When a local emergency is declared, c ities and counties sh all implement their emergency plans and take actions to mitigate or reduce the emergency threat. Actions may include deploying field-level emer gency response personnel such as law enforcement, activating emergency operation ce nters, and issuing orders to protect the public. Through a local emergency declarat ion, the air districts will obtain law enforcement aids from local governing bodi es to accomplish necessary actions for preventing ambient ozone concentration from reaching the harmful level.

Requirement of a Plan for the Prevention of Air Pollution Emergency Episodes Under the Code of Federal Regulations (CFR) 5 , areas that (1) do not attain the federal standards for ozone, and (2) have hourly ozone concentrations above 0.10 parts per million (ppm), are required to develop a cont ingency plan which must, at a minimum, provide for taking action necessary to prevent ambient ozone concentrations at any location in such region from reaching the significant harm level of 0.6 ppm, averaged over two hours. As set forth in CFR, three tr igger levels (stages) are established for the ozone pollution episodes: Al ert level (0.2 ppm), Warn ing level (0.35 ppm), and Emergency level (0.5 ppm) 6 . Corresponding actions for each specified trigger level would be identified and will be implemented when the ambient ozone hourly concentration measurements reach the speci fied trigger levels. These elements and actions should provide for rapid short-term em ission reductions at e ach trigger level, to avoid high ozone concentrations from reaching significant harm levels during an episode.

Development of the Ozone Emergency Episode Plan for Placer County Placer County is classified as non-attainment for the 2008 federal ozone eight-hour average standard 7 . Since Placer County has had more than one day with the maximum one-hour concentration gr eater than 0.10 ppm between 2011 and 2012, the Placer County Air Pollution Control District (PCA PCD) is required to prepare an ozone emergency episode plan (Plan).

Table 1 shows the number of days exceedi ng the 0.10 ppm threshold at the Placer County ozone monitoring sites from 2011 through 2014. During this time, the maximum ozone one-hour concentration was 0.11 ppm, with no site having more than three days in a year that exceeded 0.10 ppm after 2011. Fr om 2013 to 2014, there was only one day in each year that exceeded 0.10 ppm.

The industrial abatement plan is a prep lanned document prepared by a permitted industrial source (facility) whic h contains the necessary acti ons to rapidly reduce that facility’s emitted ozone precursor emissions when an epis ode level is triggered. In order to require such a plan, an emission thres hold should be established for the industrial abatement plan requirement. Depending on th e ozone emergency plans approved by the
other air districts in California , the emission thresholds to re quire the industrial abatement plan are as low as 50 tons per year for both ROG and NOx emissions 8 . Table 2 shows the five highest facilities with emissions of ROG and NOx within Placer County 9 . The table
indicates that there are two facilities in Placer County that emit more than 50 tons per year of NOx, and no facility emitting more than 50 tons per year of ROG.

Table 2 Five Highest ROG and NOx Emissions Facilities

Emissions from permitted facilities are identified as stationary source emissions. Although Placer County has two f acilities that exceed the 50 t ons per year threshold for NOx, permitted facilities comprise a very small portion of ROG and NOx countywide emission inventories. Figure 1 presents th e reactive organic gases (ROG) and nitrogen oxides (NOx) emission inventor ies in Placer County in 2012 10

.

Figure 1 Placer County 2012 Emission Inventory

According to Figure 1, 23% of ROG emissi ons and 16% of NOx emissions are from stationary sources in Placer County. Within stationary source emissions, only 11% of
ROG emissions and 27% of NOx emissions are from permitted industrial sources. Therefore, permitted industrial sources are responsible for approximately 2.7% and 4.3% of the countywide ROG emissions and NOx emissions, respectively. The major

Health Advisory Level The PCAPCD proposes 0.15 ppm as a Health Advisory level to initiate emergency actions. The Health Advisory level (0.15 ppm) is lower than the Alert level (0.2 ppm), which is the lowest of three trigger levels required by the CFR. Figure 2 represents the
annual maximum one-hour ozone concentration measured in Placer County since 1978, when air monitoring began. It also contai ns the red line showing the proposed Health Advisory level at 0.15 ppm.

Figure 2 Annual Maximum one-hour Ozone Concen tration in Placer County since 1978

*Preliminary data downloaded from ARB ADAM on 12/13/14

Figure 2 shows that the 0.2 ppm level was last reached in 1978, which was the first year of air monitoring for ozone in Placer Count y. The ozone concentration trend shows a generally consistent decrease over time, and there has not been an exceedance over 0.15 ppm in the last thirteen years (2000-2013) . Accordingly, Figure 2 shows that the
maximum ozone one-hour concentration in Pl acer County has been s ubstantially reduced and would need a high ozone concentration to trigger the Alert level, and therefore initiate the ozone emergency episode plan implementation.

Ozone concentrations in Placer County have been substantially reduced through the implementation of existing control regulati ons and programs. Place r County is located
within the Sacramento Federal Ozone Nonattainment Area (SFONA), which is designated as nonattainment for the fede ral ozone standards. Two ozone StateOzone Emergency Episode Plan Placer County Air Pollution Control District Adopted June 11, 2015 Page 6 of 11
Implementation Plans (SIP) have been develope d to identify emission control strategies
for mobile and non-mobile sources within the SFONA. Based on the SIP commitments, the PCAPCD adopted or amended rules an d developed programs to facilitate the SFONA’s progress towards attaining the federal ozone standards. The air districts within the Sacramento Region continue to work on the development of control strategies to fulfill the attainment requirement by CAA. Since the current federal ozone eight-hour average standard (0.075 ppm) is more stringen t than the previous one-hour standard, the PCAPCD believes that the development and implementation of control regulations and programs identified by the ozone SIPs will ensure that the ozone one-hour maximum concentrations in Placer County will cont inue decreasing, and would not reach the proposed Healthy Advisory level of 0.15ppm.

In addition, the PCAPCD also regulates various types of open burning, including residential, land development, fire hazard reduction, vegetation management, prescribed fire, and agricultural 11 . For the Sacramento Valley Air Basin, the PCAPCD works cooperatively with the ARB year round, and in the fall, with the Sacramento Valley Air Basin Agricultural Burn Coordinator, to provide daily burn day allocations and notifications based on meteorological condi tions and air quality forecasts. For the
Mountain Counties and Lake Tahoe Air Basins , the District works cooperatively with the ARB on the daily burn day information. The burn day information is broken down into burn day types to help indicate the qua lity of a burn day. Through the existing burn programs, the PCAPCD works carefully to balance the public health impacts from air pollution, along with the open bu rning activities wh ich exist in the county, especially since much of the county is considered a high fire hazard area.

Furthermore, the PCAPCD, along with the ot her air districts within the Sacramento Region, fund the regional “Spare the Air” pr ogram that is managed by the Sacramento Metropolitan Air Quality Manage ment District. This is an air pollution forecasting program which provides notifications to th e public on the daily ozone concentration forecasts, along with advisories with an ep isodic ozone reduction element, during the summer ozone season. It is designed to prot ect public health by in forming people when air quality is unhealthy, and by encouraging the public to reduce vehicle trips to achieve emission reductions. The program’s notifica tion includes current ozone concentration measurements from all monitoring stations within the SFONA, including Placer County, and forecasts, based on the meteorological cond itions from the national weather service advisories and local agencies. When atmos pheric stagnation conditi ons are forecasted, the public will be notified through em ail, text, or the media, that a “Spare the Air Day” is issued. The participation of the Sacramen to regional “Spare the Air” program will

11 PCAPCD Rule 301~306, http://www.placer.ca.gov/departments/air/rulesOzone Emergency Episode Plan Placer County Air Pollution Control District Adopted June 11, 2015 Page 7 of 11
promote the acquisition of forecasts of the atmospheric stagnation conditions, pursuant to the CFR requirements 12

.

In conclusion, the PCAPCD believes that th e proposed Health Advisory level at 0.15 ppm will be an appropriate and logical c ondition, in addition to the required ozone emergency episode levels set forth in the C AA, to initiate and fulfill the air pollution emergency episode actions proposed by the Plan.

Emergency Episode Criteria Table 3 summarizes the four emergency epis ode trigger levels pr oposed by the PCAPCD
for the one-hour ozone concentration meas urement in Placer County. The following section identifies the corresponding actions fo r each trigger level, when that one-hour
ozone concentration is reached.

Table 3 Trigger Levels of Ozone Emergency Episodes in Placer County

Health Advisory Alert (Stage 1) Warning (Stage 2) Emergency (Stage 3)
Ozone (one-hour average) 0.15 ppm 0.20 ppm 0.35 ppm 0.50 ppm

Proposed Actions for Ozone Emergency Episodes: The actions identified for each trigger leve l of the ozone emergency episodes include public notification and emissions mitigati on for industrial and mobile sources. The purposes of these actions are 1) to provide notification to the public when atmospheric stagnation conditions would result in su bstantially high ozone concentration measurements, and 2) to reduc e the ozone precursor emissions rapidly in order to lower
the ozone concentration below the tr iggered emergency episode level.

Air Pollution Forecast
The PCAPCD continues to use the Sacramen to regional “Spare th e Air” program to provide public notification for air quality forecasts when atmospheric stagnation conditions would result in substantially high ozone concentrati on measurements. The notification with episodic ozone reduction strategies is to encourage the public to take voluntary actions to reduce ozone precursor emissions.

Emergency Episode Declaration Whenever the ozone one-hour concentration, measured at any location within Placer County, reaches or is predicted to reach any of the episode trigger levels as shown in

12 40 CFR 51.152 “Contingency Plans”Ozone Emergency Episode Plan Placer County Air Pollution Control District Adopted June 11, 2015 Page 8 of 11

Table 3, the PCAPCD shall declare that an emergency episode is in effect in Placer County.

In addition, should the Air Pollution Control O fficer (APCO) of a district adjacent to the PCAPCD declare a stage 1, 2, or 3 episode within that district and re quest assistance, the APCO of PCAPCD may implement measures as described in this Plan as if such episode
level has been measured within the District.

Notification of an Emergency Episode
The PCAPCD shall establish a nd periodically update and re view an emergency episode notification list (List). When any emergency episode is declared, the APCO shall notify
the officials on the List. The Li st shall include, and is not limited to, the following public agencies and organizations:
