EXECUTIVE SUMMARY:

Santa Barbara County Air Pollution Control District’s ( APCD ) Rule 352, Natural Gas

Fired Fan

- Type Central Furnaces and Residential Wate r Heaters , regulates oxides of nitrogen (NOx) emissions from natural gas

- fired central furnaces and small water heaters

with a heat input rating less than 75,000 British thermal units (Btu) per hour

. Rule 352 is a point

- of

- sale rule.- 2

- The 2010 APCD Clean Air Plan (CAP) includes a commitment for the APCD to adopt a

control measure for gas

- fired small water heaters subject to Rule 352 by reducing the

curr ent NOx limit of 55 parts per million (ppm) to 15 ppm. Proposed amended Rule 352

fulfills this commitmen t. The NOx emission limits for natural gas

- fired fan

- type central

furnaces subject to Rule 352 will remain at 55 ppm.

DISCUSSION:

Background

T he 2010 CAP calls for the adoption of CAP control measure N

- XC

- 1 to further control

NOx emission s from natur al gas

- fired small water heaters with a heat input rating less than 75,000 Btu per hour

. This control measure would reduce the current small water

heater NOx limit of 55 ppm to 1 5 ppm.

The proposed emission limit revision for small water heaters is consi stent with the limits already adopted by the Sout h Coast Air Quality Management District , the Ventura County Air Pollution Control District and the San Joaquin Valley Unified Air Pollution

Control District

.

The emission limits for central furnaces subject to Rule 352 will remain unchanged at 55

ppm

.

M anufacturers have made water heaters which comply with the 15 ppm limit for almost four years

. These compliant water heaters have been available in Southern Californ i a
, Ventura and San Joaquin Valley for som e time now and some are already being sold in Santa Barbara County.

Rule 352 Revision

The primary objective of this rule revision project is to redu ce small water heater NOx

emissions limit from 55 ppm (approximately 40 nanograms per joule) to 15 ppm ( approximately 10 nanograms per joule ). The revision also adds a sell

- through provision that enables distributors to sell existing water heaters that do not meet the 15 ppm limit until July 1, 2012.

APCD staff have revised the title to read “Small” water heaters instead of “Residential”

water heaters. As a result, the revised new title is “Natural Gas

- Fired Fan

- Type Central

Furnaces and Small Water Heaters”. This revision was made to include all water heaters of this size (i.e., residential and commercia l) in order to have similar requirements as other surrounding Air Districts. Ventura County APCD revised their same size water heater rule last year and also revised their applicability to read “any/all” (as opposed to residential) water heaters.- 3

- Staff h a ve also proposed minor editorial revisions for clarity.

I mplications for Sources

There are no small water heater manufacturers in Santa Barbara County. In order to comply with the South Coast A ir Q uality M anagement D istrict and Ventura County A ir

P oll ution C ontrol D istrict 15 ppm requirement, most manufacturers producing these

water heaters have obtained certification from South Coast AQMD that their units meet

the 15 ppm NOx emission limit. The amended Rule 352 will accept this certification.

Conseq uently, s ources in Santa Barbara County that need to replace water heaters with

new units will be able to purchase compl iant units from vendors. This rule revision also does not require that existing units be immed iately replaced upon adoption. Rule 352

r emains a point

- of

- sale rule and includes sell

- through provision that enables distributors to sell and sources to install units which comply with the current 55 ppm NOx limit until July 1, 2012.

The APCD does not expect there will be an y direct effect on t he sources of Santa Barbara County due to this revision to Rule 3 52

.

Implications for APCD Budget

APCD staff will not incur additional routine or ongoing costs associated with this rule

revision. This rule revision is being applied to an existing poi nt

- of

- sale rule and will not

create addi tional staff time and costs nor will it affect the APCD budget.

Comparison to Existing Federal Requirements

Pursuant to the Health and Safety Code Section 40727.2 (a) , the APCD is required to

identi fy any and all existing federal air pollution control requirements that apply to the same equipment or source category as the rule proposed for adoption or modification by

the APCD. Section 40727.2(a) also requires the APCD to identify any of the APCD’s existing or pro posed rule and regulations that apply to the same equipment.

There are no federal regulati ons that apply to natural gas small water heaters less than 75,000 Btu per hour. Table 1 , below, includes a list of the APCD rules and regulations that apply to th e same equipment.- 4

Review All emission units Addition of new equipment or modification to existing equipment. Applications to generate ERC Certificates. Regulation XIII (Rules 1301

- 1305) : Part 70 Operating Permits All emission units A stationary source is a major

source.

Emission Reductions

As a result of the proposed lower NO

x emission limits

, emission reduc tions will occur

over time through the normal rate of replacement of old water heaters. The lifespan of these small water heaters ranges from 10 to 15 years. S taff estimates that the NOx emissions reduced by this rule change will be an additional 0. 0867 tons per day ( 31

. 65

tons per year ) in 2020 and 0.1653 tons per day (60.33 tons per year) in 2030

.

Rulemaking Process and Schedule

Staff prepared the proposed amended R ule 352 and distributed it in July, 2011.

APCD staff informed affected manufactur ers, suppliers, installation specialists and

associations of this proposed amended rule

. The proposed amen ded R ule 352 was

distributed via regular mail to those affected manufacturers, suppliers, and distributors of

small water heaters . Additionally, sta f f posted this proposed amended R ule 352 on the

APCD website.

Staff presented the proposed revisions for this rule to the Community Advisory C ouncil (CAC) at their August 10 , 2011 meeting. The CAC recommended that the Board adopt

the p roposed a mended Ru le 352

. Th e motion passed with a vote of 14:0:0

.- 5

- Public Review: Public Comments Submitted to Date

Attachment 3 contain s written public comments received to date and staff responses.

APCD staff ha s not received any public comments on th is amended r ule to date.

Cost

- Effectiveness

The cost

- effectiveness of air pollution control rules is generally specified in terms of cost of compliance per ton of emissions reduced. The South Coast AQMD estimated the c ost

effectiveness for the same control measure ranges from $2,979 to $9,292 per ton of NOx reduced (based on an incremental cost i ncrease of $15 to $50 per unit).

With both Ventura County APCD and South Coast AQMD rule s requiring 15 ppm water heaters, manufacturers already make units that comply with the proposed amended Rule

3 52 NOx limit

. Based on information provided by vendors and manufacturers of water
heaters , and the fact that the limit in proposed amended Rule 352 is already being

achieved in other nearby air d istricts

, there should only be a minor increase in cost for compliant water heaters

.

California Environmental Quality Act

The California Environmental Quality Act (CEQA) requires environmental review for the

pro po sed amendments to Rule 352, Natural Gas

- Fired Fan

- Type Central Furnaces and

Small Water Heaters

.

The Santa Barbara County APCD is the lead agency on this project. P roposed

amended Rule 352 has been examined in the Environmental Impact Report (EIR) for the

2010 CAP which concluded that the implementation of revised Rule 35 2 would not result in any significant environmental impacts.

The APCD finds that the 2010 CAP EIR may be used to fulfill the environmental review requirements of the current project. CEQA Guidelines section 15168 (c) (2) allows subsequent activities to b e approved without the need for a new environmental document if the impacts of those activities were examined in an EIR, and have no new effects or mitigation measures. District staff have evaluated the environmental impacts related to Proposed Amended Ru le 352, and have concluded that the environmental impacts were adequately analyzed in the 2010 CAP EIR.

CEQA f indings to be adopted by the APCD Board , as well as a discussion of the se finding s
, a re provided in Attachment 1.

FISCAL IMPACT:

The APCD cost of implementing proposed amended Rule 352 will not change as a result of this rule revision. This is a point

- of

- sale rule and as a result, compliant water heaters- 6

- will be purchased when existing units need replacement. This normal routine repla cement of water heaters will not have any impact on the APCD ’s budget . The standard APCD fees for certification and/or source testing in Rule 210 will apply for manufacturers to pay for in

- house staff review or compliance activities that may be

necessary
