Q

Describe AB 617, the part that does NOT have to do with air monitoring.

A

AB 617 was signed into law in July 2017. Among its provisions, California Health and Safety Code (HSC) section 40920.6 was amended to require each air district that is a nonattainment area for one or more air pollutants to adopt an expedited schedule for implementation of Best Available Retrofit Control Technology (BARCT). This requirement applies to each industrial source subject to the California Greenhouse Gas Cap-and-Trade regulation.

Q

Explain the Air Toxic “Hot Spots” Act.

A

California enacted The Air Toxics “Hot Spots” Information and Assessment Act in 1987. The Act establishes a formal air toxics emission inventory risk quantification program, which is managed by California air districts.

The program goals include:

collection of data on the emission of toxic air contaminants

identification of facilities having localized impacts

health risk assessment

public notification on health risks

reduction of the risks of “significant-risk facilities” below the level of significance

Describe the ‘primary’ and ‘secondary’ data sets in Purple Air.

A

The PurpleAir sensor has two ‘channels’ that measure data. Channel A and Channel B. Each channel has a ‘primary’ and ‘secondary’ data set:

Primary Data: measured in µg/m3

Secondary Data: measured in particles/deciliter

µg/m3 is the particle mass concentration - the popular method of measuring particulate matter.

Particles/deciliter is a particle count per volume measurement.

A

The Global Warming Solutions Act of 2006 is a California State Law that fights global warming by establishing a comprehensive program to reduce greenhouse gas emissions from all sources throughout the state.

AB 32 requires CARB to develop regulations and market mechanisms to reduce California’s greenhouse gas emissions to 1990 levels by the year of 2020, representing approximately a 30% reduction statewide, with mandatory caps beginning in 2012 for significant emissions sources.

Community Air Protection Program. Established by CARB in response to AB 617. The Program’s focus is to reduce exposure in communities most impacted by air pollution. How:

  1. targeted incentive funding to deploy cleaner technologies
  2. grants to support community participation
  3. new requirements for accelerated retrofit of pollution controls on industrial sources
  4. increased penalty fees, and greater transparency and availability of air quality and emissions data
104
Q

Name NO. What role does it play in air pollution?

A

Nitric oxide.

It contributes to the formation of smog and acid rain.

105
Q

Define PM10.

A

PM10 = All particles with an aerodynamic diameter of 10 μm or less.

106
Q

Name N2O. What role does it play in air pollution?

A

Nitrous oxide.

It plays no role in air pollution, but it may affect the ozone layer, and it is a greenhouse gas.

It is used as an anesthetic, propellant for sprays, and as an oxidizer in engines.

107
Q

Name NO2. What role does it play in air pollution?

A

Nitrogen dioxide.

It contributes to the formation of smog and acid rain.

108
Q

Describe FEM and FRM.

A

FRM = Federal Reference Method = This refers to an air pollution measurement device that has been developed to a clearly defined standard for a specific criteria pollutant.

FEM = Federal Equivalent Method = Air pollution measurement devices incorporating new technologies are tested and evaluated through the equivalent method process.

109
Q

How do Field Operations staff enforce rules?

A

A Notice of Violation (NOV) or a Notice to Comply (NTC) may be issued when Sac Metro Air District Field Operations staff observe a violation of air quality PERMITS OR RULES. Any individual or business receiving an NOV or NTC from a representative of the Sac Metro Air District should immediately take all reasonable and prudent steps necessary to get back into compliance.

After the case is reviewed, written notification will be sent of the Sac Metro Air District decision to either:

  1. Offer the opportunity to resolve the violation through the Mutual Settlement Program
  2. Refer the case to Sac Metro Air District legal counsel
  3. Refer the case to the District Attorney
110
Q

Name the 4 substances that have a California standard, but no federal standard.

A
  1. Hydrogen sulfide (H2S)
  2. Sulfates
  3. Visibility-reducing particles
  4. Vinyl chloride (aka chloroethene)
111
Q

How water-soluble is sulfur dioxide? What does this mean about where in the airway it is removed?

A

It is very water-soluble, so it is removed by the upper airway.

112
Q

Name and describe Rule 207.

A

Name: Title V - Federal Operating Permit Program.

This Rule establishes an operating permit system that is consistent with federal Title V requirements.

113
Q

How do you evaluate pollution threshold?

A

Organisms and ecosystems tend to tolerate pollutants up to a critical amount of pollutant accumulation, responding slowly up to the critical threshold. Beyond the threshold, scientists observe undesirable, and sometimes rapid, changes. The best limits are set at these thresholds, the authors say.

114
Q

What is the name AND title of the leader of SMAQMD?

A

Dr. Alberto Ayala

Air Pollution Control Officer / Executive Director

115
Q

Did CARB select any AB 617 communities within SMAQMD?

A

On September 27, 2018, CARB selected 10 communities across the state to be the first communities to develop and implement a community emission reduction plan and/or an air monitoring plan. The South Sacramento - Florin community was one of the 10 to be selected.

The South Sacramento - Florin community was identified for air monitoring. In future years, the information collected from air monitoring will provide valuable information for the development of emission reduction strategies in the South Sacramento - Florin community to reduce air pollution burdens.

116
Q

Define cogeneration.

A

the generation of electricity and other energy jointly, especially the utilization of the steam left over from electricity generation to produce heat.

117
Q

Define SFNA.

A

Sacramento Federal Nonattainment Area

118
Q

What certification would I be required to get, and what is the deadline?

A

CARB Visible Emissions Evaluation certificate, within 6 months (for inspection positions, which I assume this is).

119
Q

Why does Sacramento have bad air quality?

A
  1. poor atmospheric ventilation
  2. a capping temperature inversion
  3. bordering mountains
  4. sunny days

These 4 factors enhance smog formation and effectively trap pollutants in the Basin.

120
Q

Name some broad examples of stationary sources of pollution.

A
  1. fuel combustion (e.g., space and water heating)
  2. waste disposal (e.g., landfills and composting)
  3. cleaning and surface coatings (e.g., auto refinishing and furniture coatings)
  4. petroleum production and marketing (e.g., bulk gasoline storage and transfer)
121
Q

Who is Darrell Singleton?

A

Program Supervisor, Field Operations, Stationary Sources.
