2. State Requirements
a. California Health & Safety Code, Part 6 (commencing with section 44300) -- Air Toxics "Hot
Spots Information and Assessment Act of 1987:
Facilities subject to this requirement must identify and quantify emissions of toxic air
contaminants. Facilities posing a potential health risk to the public must prepare a health risk
assessment and if required, notify the public and implement a risk reduction plan.
b. California Health & Safety Code §42301.6 -- Permit Approval: Powers & Duties of APCO:
Prior to approving an application for a permit to construct or modify a source which emits
hazardous air pollutants, which source is located within 1,000 feet from a school site, the
District must prepare a public notice. The notice must be sent to parents or guardians of
children enrolled in any school located within 1/4 mile of the source and to each address
within a radius of 1,000 feet of the source at least 30 days prior to taking final action on the
application. In addition units locating within 1,000 feet from a school may be required to
reduce hazardous air pollutant emissions and their associated health risk to the maximum
extent deemed practicable. This may include, but is not limited to, emissions limitations,
stack height requirements, and hours of operation restrictions.
3. Federal Requirements
1. National Emission Standard of Hazardous Air Pollutants (40 CFR Part 63)

2. Nuisance – Public Health
a. Toxics Review (T-BACT):
Toxic best available control technology is required for all sources that have combined
emissions of toxic air contaminants exceeding 1 theoretical lifetime cancer cases per million
individuals and/or exceeding a non-cancer health risk Hazard Index (HI) of 1.
V-7
b. Toxics Review:
The District evaluates the impact of airborne toxics released from a facility or project pursuant
to SMAQMD’s guidance document, HEALTH RISK MANAGEMENT PROGRAMS FOR
EXISTING, MODIFIED AND NEW STATIONARY SOURCES. The action levels are
summarized below. Please refer to the actual guidance document for more detail on how to
calculate and interpret health risk:
Cancer Risk:
Excess Cancer Risk
Action Required
≤ 0.1 per million
Exempt from further toxic review.
> 0.1 per million but ≤ 1 per million
No significant risk; No action required.
> 1 per million but ≤ 10 per million
Acceptable risk; Provide TBACT
> 10 per million but ≤ 100 per million
Permit denied unless the APCO makes a
finding that not approving the project may
result in a greater negative impact to the public
than approving the project.
> 100 per million
Denial of permit.
Non-Cancer Health Risk (Acute and Chronic):
Hazard Index (HI)
Action Required
HI < 1
Health risk is within acceptable range
HI ≥ 1
Consult OEHHA for further guidance
When evaluating the cancer and non-cancer risks, the specific toxic air pollutants that need to
be addressed are those that have potency values or reference exposure levels identified in
the OEHHA’s Health Risk Assessment Guidelines
(http://www.oehha.ca.gov/air/hot_spots/index.html)
c. T-BACT:
T-BACT requirements are in general not triggered for boilers. A determination will be made at
the time of application if a particular project triggers the requirement and the mitigation
needed.
3. New Source Review -- BACT
a. Applicability:
Rule 202, Section 301 (10/28/2010) and Rule 214, Section 301, requires that any new or
modified emissions unit which results in an increase in potential quarterly emissions for any
affected pollutant must apply Best Available Control Technology (BACT) for that pollutant.
The Rule 202 BACT threshold will not generally apply to units installed prior to August
18, 2011, so long as:
1. The unit is not located at a major stationary source, and
2. The unit does not emit greater than 30 pounds per month of regulated
pollutants.
V-8
b. BACT Determinations:
Applicants must provide BACT for previously unpermitted, new or modified stationary sources
where the emission unit has a positive quarterly emission increase and the maximum daily
emissions are equal to or greater than the limits stated in Rule 202 or 214.
Note: The standards specified in this document serve as guidance and reflect the minimum
emission rate/control technology that will be required as BACT. BACT DETERMINATIONS
MAY CHANGE AT ANY TIME AND WITHOUT PREVIOUS NOTICE. Please contact
SMAQMD for the latest BACT determinations.

The SMAQMD has developed a comprehensive permitting CEQA Guidance document. Project
reviews conducted in accordance with the policy manuals contained therein (including this
manual) have been determined to meet the CEQA criteria of ministerial and do not require
additional CEQA review.
In the event a project falls outside the scope of this policy manual (for example a new BACT
determination or other situation already described within the CEQA guidance document), the
project shall follow the steps for CEQA review as detailed in the guidance document."
5. Rule 217 – Public Notice Requirements for Permits

(A)The Value of NOx is derived from Rule 411 and is based on the size of the unit, the value of
ROC, SOx PM10 and CO are derived from Table 1.4-2 (7/98) in US EPA AP-42. PM10 and
PM2.5 are assumed equal .Emission calculations are based on 1028 BTU/SCF, for natural gas
(B) GHG emission factor is expressed as CO2e and is from EPA’s Mandatory Reporting of Greenhouse
Gases Rule (74 FR 56260), Tables C-1 & C-2. All emission limits are in English units.
Sample Quarterly Emissions Calculation (example)
2 MMBTU/hr natural gas fired boiler
1,000 BTU/cf (standard assumption for gaseous fuels)
Continuous operation
Quarterly NOx emissions from boiler = (2 MMBTU/hr)*(36.4 lb/MMcf)*(1 MMcf/1,000
MMBTU)*(24 hr/day)*(92 days/qtr)
= 161 lb/qtr.

= 0.005988159 gr/dscf
2.
Calculate CO2 emission factor (lb CO2/MMBTU) assuming 100% C to CO2 conversion

3.
Calculate lb CO2/MMBTU at 99.5% Conversion
= 121.7991895 lb CO2/MMBTU x 99.5%
= 121.1901936 lb CO2/MMBTU
4.
Calculate volume % of CO2 in Exhaust Gas
= % CO2
= mol CO2/mol exhaust
= (121.1901936 lb CO2/MMBTU) x (mol CO2/44 lb CO2) x (MMBTU/8710 dscf) x (385.3 dscf/mol exhaust)
= 0.121841618 mol CO2/mol exhaust or 12.1841618 % CO2
5.
Calculate corrected grain loading
= (0.005988159 gr/dscf) x (12% CO2/12.089% CO2)
= 0.0059 gr/dscf corrected to 12% CO2
OR

= (7.6 lb/MMcf) x (7000 gr/lb) x (0.12 mol CO2/mol exhaust) x (lb fuel/0.76 lb C) x (12 lb C/mol C) x (mol C/mol CO2) x
(MMcf/44582 lb fuel/) / (0.995) x (mol exhaust/385.3 dscf)

SO2 Concentration (% SO2 by volume):
The following calculation is at 0% excess air which represents worst case.
= (0.6 lb SO2/MMcf) x (MMcf/1020 MMBTU) x (MMBTU/8710 dscf) x (mol SO2/64 lb SO2) x (385.3 dscf/mol exhaust)
= 0.000000407 mol SO2/mol exhaust or 0.0000407 % SO2
The rule emission limits for SO2 and PM are 0.2% SO2 by volume and 0.1 grains/cf at 12%
CO2, respectively. Therefore, the emissions from the boiler comply with Rule 406.
Rule 411 – NOx from Boilers, Process Heaters and Steam Generators.
This rule limits NOx emissions from boilers. This boiler is subject to this rule, since the
products of combustion do not come in direct contact of the material to be heated and the
boiler is rated greater than 1 MMBTU/hr. Since this boiler is rated at 5.1 MMBTU/hr, the rule
requires a NOx emission rate of 15 PPM and CO of 400 PPM, and source testing initially and
every other year. The applicant has submitted information that shows that the boiler will meet
the emission requirements, and the source testing requirements will be conditions of the
Authority to Construct and Permit to Operate.
Rule 420 - Sulfur Content of Fuels
This rule limits the sulfur content of all gaseous fuels to less than 50 grains per 100 cubic
foot, calculated as hydrogen sulfide (H2S). Pipeline natural gas in Sacramento County has a
sulfur content of 0.22 grains per 100 cubic foot. Therefore, the boiler will comply with the
requirement of this rule.
5. NSPS COMPLIANCE:
The list of all adopted New Source Performance Standards as listed in 40 CFR 60
(http://yosemite.epa.gov/r9/r9nsps.nsf/ViewStandards?ReadForm&Part=60) were reviewed
to determine if the proposed project is subject to one or more of these regulations. There
are currently no NSPSs applicable to this source category.
For reference purposes, 40 CFR Part 60, Subpart Dc – Standards of Performance for Small
Industrial-Commercial-Institutional Steam Generating Units will be discussed here. This
regulation applies to steam generating units that were constructed, modified, or
reconstructed after June 9, 1989 and has a design heat input capacity from 10 MMBTU/hr
up to 100 MMBTU/hr. Because the proposed boiler has a heat input rating of 5.1
MMBTU/hr, the boiler is not governed by this rule.
6. NESHAP COMPLIANCE:
NESHAPs under 40 CFR, Part 61: The list of all adopted National Emission Standards for
Hazardous Air Pollutants (http://yosemite.epa.gov/r9/r9nsps.nsf/ViewStandards?ReadForm&Part=61)
were reviewed to determine if the proposed project is subject to one or more of these
regulations. There are currently no 40 CFR, Part 61 NESHAPs applicable to this source
category.
NESHAPs under 40 CFR, Part 63: The list of all adopted National Emission Standards for
Hazardous Air Pollutants (http://yosemite. .gov/r9/r9nsps.nsf/ViewStandards?ReadForm&Part=63)
