We proposed to approve this rule because we determined that it complied with the relevant CAA requirements. Our proposed action contains more information on the rule and ourThis document is a prepublication version signed by EPA Acting Regional Administrator Alexis Strauss on August 15, 2016. We have taken steps to ensure the accuracy of this version, but it is not the official version. evaluation. II. Public Comments and EPA Responses The EPA’s proposed action provided a 30-da y public comment period. During this period, which ended on October 30, 2015, we received comments from Adenike Adeyeye, Earthjustice. 1 Summaries of the comments are provided below, along with our responses to those

comments. Comment #1: Earthjustice commented that, “[t] he previous iteration of Rule 4901, amended in 2008, banned the use of [all] wood burning devices when the forecasted PM 2.5 concentration exceeded 30 [micrograms per cubic meter (μg/m 3 )]”, while the submitted rule allows use of registered devices 2 until forecasted PM 2.5 concentrations reach 65 μg/m 3

. Earthjustice argued that this revision, which allo ws registered devices to burn and emit PM equal to or less than 2.5 microns in diameter (PM 2.5 ) while the San Joaquin Valley Air Basin is violating the 2006 24-hour PM 2.5 standard, constitutes a relaxati on of restrictions on burning for registered wood burning devices that violates CAA section 11 0(l). Earthjustice noted that SJVUAPCD justified this relaxation by predictin g drastic emission reduc tions from replacement of existing wood burning devices, but asserted th at SJVUAPCD’s claim that the relaxation is irrelevant because the associated emissions are low is incorrect. Response #1: We disagree with the commenter’s cl aim that the rule revisions are a relaxation that violates CAA sec tion 110(l). As an initial matter, section 110(l) does not prohibit all relaxations of individual SIP-approved rule provisions. Rath er, section 110(l) prohibits the EPA from approving a SIP revision that “would interfere with any applicable requirement

1 Letter and email from Adenike Adeyeye, Earthj ustice, dated and received October 30, 2015. 2 Submitted Rule 4901, Paragraph 5.7.1 sets eligibility require ments for District registration of wood burning heaters that may be used during a Level One Episodic Wood Burnin g Curtailment. The heaters must be either exempt from EPA certification requirements or EPA- certified as specified under the New Source Performance Standard (NSPS) for New Residential Wood Heaters (40 CFR part 60, subpart AA A) in effect at the time of purchase or installation.This document is a prepublication version signed by EPA Acting Regional Administrator Alexis Strauss on August 15, 2016. We have taken steps to ensure the accuracy of this version, but it is not the official version. concerning attainment and reasona ble further progress (as defined in [CAA section 171]), or any other applicable requirement of [the CAA].” The EPA’s c onclusion that Rule 4901 will not interfere with attainment is not based on low emi ssions associated with the revision of the SIP to allow registered devices to be used when forecasted concentrations are between 30 and 65 μg/m 3 , as the commenter asserts. The commenter focuses only on this provision of Rule 4901 and ignores the associated requi rement that unregistered devices can no longer be used when forecasted concentrations are above 20 μg/m 3 . Contrary to the commen ter’s suggestion, the EPA is not required under section 110(l) to evaluate each individual revision to Rule 4901 separately from all other revisions to Rule 4901. Accordin gly, the EPA’s analysis of Rule 4901 considers both provisions in conjunction. As discussed in the EPA’s Technical Support Document supporting our proposed approval of Rule 4901 (“Rule 4901 TSD”), 3 SJVUAPCD estimates that reducing the PM 2.5 forecast level at which unregistered devices are banned from 30 to 20 μg/m 3 decreases average wood burning season emissions by 3.33 tons per day (tpd) PM 2.5 , while allowing registered devices to burn when forecasted concentrations are between 30-65 μg/m 3 increases emissions by 0.065 tpd PM 2.5 . Combining these changes yields an ove rall estimated emission reduction of 3.27 tpd PM 2.5 when compared to the SIP-approved rule. 4 Therefore, projected increases in emissions from registered devices are more than offs et by the emission reductions achieved by the

3 See Technical Support Document for the EPA’s Proposed Rulemaking for the California State Implementation Plan, San Joaquin Valley Unified Air Pollution Control Di strict Rule 4901, Wood Burning Fireplaces and Wood Burning Heaters, August 2015, (“Rule 4901 TSD”) page 8. 4 As noted in the Rule 4901 TSD, the SIP-approved version of Rule 4901 contains a contingency provision which would have come into effect if the EPA had found that the SJV had failed to attain the 1997 PM 2.5 National Ambient Air Quality Standards (NAAQS or “standards”) by the app licable deadline. That provision would have reduced the mandatory curtailment PM 2.5 forecast threshold from 30 to 20 μ g/m 3 for all wood burning devices. However, we have not made a finding that the SJV failed to attain the 1997 PM 2.5 NAAQS by the applicable deadline, so the contingency provision has not been triggered. Moreover, we have withdrawn our approval of and disapproved the State’s 2013 Contingency Measure Subm ittal, which relied, among other things on the contingency provision in Rule 4901. 81 FR 29498 (May 12, 2016). Accordingly, we believe the appropriate point of comparison for purposes of 110(l) is the SIP-approved rule without the contingency measure (i.e., a mandatory curtailment PM 2.5 forecast threshold of 30 μ g/m 3 for all wood burning devices).This document is a prepublication version signed by EPA Acting Regional Administrator Alexis Strauss on August 15, 2016. We have taken steps to ensure the accuracy of this version, but it is not the official version. enhanced curtailment criteria for unregistered stov es. Contrary to the commenter’s assertion, this evaluation does not rely on exp ected additional change-outs to cleaner burning devices, which would lead to additional emi ssion reductions beyond 3.27 tpd PM 2.5 . Thus, the revisions to Rule 4901 are expected to result in significant emission reductions overall compared to the current SIP-approved version of the rule, which will help to expedite attainment of the PM 2.5 NAAQS in the San Joaquin Valley (SJV). Accordingly, we find that the revisi ons to Rule 4901 are consistent with the development of an overall plan for attaining the NAAQS in the SJV. With regard to other applicable requirements of the CAA, for the reasons explained in our proposal, TSD and in response to comments be low, we also find that Rule 4901 implements reasonably available control measures (RACM) a nd best available control measures (BACM) for
PM 2.5 emissions from wood burning de vices in the SJV. Therefor e, we conclude that the revisions to Rule 4901 will not interfere with an y applicable requirement concerning attainment and reasonable further progress or any ot her applicable requirement of the CAA.
Comment #2: Earthjustice commented that th e Bay Area Air Quality Management District (BAAQMD), South Co ast Air Quality Management District (SCAQMD), and Sacramento Metropolitan Air Quality Management District (SMAQMD) in clude more stringent curtailment requirements as they apply to register ed devices. In particular , Earthjustice noted that SCAQMD and BAAQMD ban the use of all w ood burning devices when the forecasted PM 2.5 concentration exceeds 30 μg/m 3 and 35 μg/m 3 , respectively. SMAQMD limits burning using a tiered system, banning the use of registered devices when the forecasted PM 2.5 concentration exceeds 35 μg/m 3 . As a result, Earthjustice argued that “[t]he changes to rule 4901 do not meet the requirements for reasonably available contro l measures (RACM) or BACM for registered wood burning devices.” Response #2: The commenter appears to assume that we must evaluate RACM andThis document is a prepublication version signed by EPA Acting Regional Administrator Alexis Strauss on August 15, 2016. We have taken steps to ensure the accuracy of this version, but it is not the official version. BACM for registered (clean burning) devi ces separately from RACM and BACM for unregistered devices. We do not agree with th is premise. Nothing in the CAA or EPA’s implementing regulations requires us to consider the stringency of requirements for registered devices separately from the stringency of require ments for unregistered devices. Furthermore, the purpose of the two-tiered curtailment system is to encourage replacement of unregistered devices with registered devices, so it is reasonable to consider the requirements applicable to registered and unregiste red devices together. 5 As explained above, SJVUAPCD estimates that the emissions from registered clean burning devices when concentrations are above 30 μg/m 3 will be overwhelmingly compensated for by decreased emissions from unregistered devices when concentrations are between 20-30 μg/m 3 , making the Rule 4901 curtailment program at least as stringent as or more stringent than these and other analogous curtailment programs. 6 The commenter has not provided informa tion that contradicts the District ’s assessment in this regard.
Comment #3: Earthjustice asserted that the controls on the installation of wood burning devices in new developments are less stringent than those used by SCAQMD and BAAQMD. In particular, the commenter noted that SCAQMD Rule 445 prohibits the installation of any wood burning device in new development, except where there is no existing infrastructure for natural gas within 150 feet of the property line or those 3,000 feet above sea level. 7 In addition, the commenter stated that “BAAQMD recently became th e first air district in the nation to ban the installation of wood burning device s in any new development.” Response #3: Rule 4901, Paragraph 5.3 limits the number of wood bur ning devices that can be installed in new residential developments . In residential developments with a density

5 For example, on page 45 of Final Staff Report for Amendments to the District’s Residential Wood Burning Program, SJVUAPCD, dated September 18, 2014, SJVUAPCD explains that 29% of survey respondents indicated that they would replace their current wo od burning fireplace or wood burning h eater with a cleaner device if allowed to burn more often. 6 See Rule 4901 TSD, page 11. 7 SCAQMD, Rule 445: Wood Burning Devices, Section f(2) (amended 5/3/13).This document is a prepublication version signed by EPA Acting Regional Administrator Alexis Strauss on August 15, 2016. We have taken steps to ensure the accuracy of this version, but it is not the official version. greater than two dwellings per acre, no wood burning fireplaces are allowed and a maximum of two certified wood burning heaters per acre are allowed. In developments with a density less than or equal to two dwellings per acre, one wood burning fireplace or certified wood burning heater is allowed per dwelling. As discussed in Rule 4901 TSD at page 12, “SJVUAPCD states that Rule 4901 is more string ent than SCAQMD Rule 445 as it does not exempt any homes at any elevation. 8 Given the lack of any exemptions in Rule 4901, it is reasonable to conclude that Rule 4901 is at least as stringent as SCAQMD Rule 445.” The commenters have not provided new information to contra dict this conclusion. The ban on wood burning devices in new c onstruction in BAAQMD Regulation 6-3 was enacted on October 21, 2015, more than a year after SJVUAPCD had amended Rule 4901 on September 18, 2014, and does not become effective until November 1, 2016. 9 Given that no other State or district had enacted a complete ban at the time that SJVUAPCD was revising Rule 4901 and conducting its BACM analysis and no such ban has yet become effective in any State or district, we do not believe it is reasonable to disapprove Rule 4901 for failing to include such a ban. However, we recommend that SJVUAPCD eval uate the feasibility of such a ban in the SJV and revise Rule 4901 to include such a ban, if it is found to be feasible.
Comment #4: Earthjustice commented that Rule 4901’s incentive of fewer no-burn days for registered devices is ina ppropriate and unnecessarily adds air pollution. Earthjustice argued that SJVUAPCD’s well-funded financ ial incentives program is suffi cient to motivate a switch to registered wood burning devices and allowing these devices to burn additional days is an unnecessary additional incentive. Further, Earthj ustice suggested, if the District offers an additional “incentive of fewer no burn days, the limit for registered devices should be 30 μg/m 3 ,

In reviewing SIP submissions, the EPA’s role is to approve state c hoices, provided that they meet minimum criteria set by the CAA an d any applicable EPA regulations and are reasonable. We conclude th at allowing clean burning de vices to burn when the PM 2.5 concentration is forecasted to be between 20-65 μ g/m 3 is reasonable and, as described in Response #1 and #2 above, complies with relevant CAA requirements.
Comment #5: Earthjustice argued that the District should be re quired to incorporate the EPA’s recommendations into Rule 4901. In particul ar, Earthjustice asserted that the District should: (1) not subsidize the tr ansition to wood burning heaters, which are generally used more frequently than gas fireplaces; (2) require re trofit of existing wood burning fireplaces during major renovations; and (3) require homes where wood burning devices are the sole source of heat to meet current EPA certification requirement s. Earthjustice noted that requirements similar to (2) and (3) were recently added to the BAAQMD rule. Response #5: While we agree that SJVUAPCD should consider eliminating subsidies for transition from fireplaces to wood burning heater s, details regarding the implementation of SJVUAPCD’s monetary incentive program have not been submitted into the SIP and are outside of the scope of this rulemaking. Regarding retr ofits of wood burning fi replaces during major

We have taken steps to ensure the accuracy of this version, but it is not the official version. renovations, at the time of Rule 4901 adoption and proposal, Laguna Beach, California was the only area we were aware of that required fi replace retrofits upon ma jor home renovation. While we recommended SJVUAPCD examine the feasibility of including this provision, its existence in one small southern California city is not a suffi cient basis for determining that it is feasible in the much larger and more diverse SJV. As noted by the commenter, on October 21, 2015, BAAQMD adopted a requirement th at a gas-fueled, electric, or EPA-certified device be installed upon remodel of a fireplace or chimney where total costs exceed $15,000 and a local building permit is required. Given that no other State or district had adopted a similar provision at the time that Rule 4901 was revised, we do not believe it is reasonab le to disapprove Rule 4901 for failing to include such a provision. However, we continue to recommend that SJVUAPCD consider the feasibility of implementing such a pr ovision in the SJV, partic ularly in light of the newly-enacted BAAQMD provision. Similarly, we do not believe it is reasonable to disapprove Rule 4901 for failing to require sole-source househol ds to meet EPA certification requirements, as no other State or district had adopted a similar provision at the time that Rule 4901 was amended. In the Rule 4901 TSD, Attachment 1 11 , we compared Rule 4901 to analogous district rules, and found SJVUAPCD implements a collecti on of measures as stringent as or more stringent than these rules. We agree that SJ VUAPCD should consider our recommendations for future rule revisions, but they do not affect our conclusion that Rule 4901, as amended, strengthens the SIP, decreases PM 2.5 emissions, and currently impl ements BACM/Best Available Control Technology (BACT) for wood burning devi ces. Additionally, the rule fulfills the relevant CAA section 110 and Title I Part D re quirements. Therefore, we conclude that our recommendations for rule revisions do not provide a basis for rule disapproval.

EPA Action No comments were submitted that change our assessment of the rule as described in our proposed action. Therefore, as authorized in s ection 110(k)(3) of the Act, the EPA is fully approving this rule into the California SIP. IV. Incorporation by Reference In this rule, the EPA is finalizing regulatory text that includes incorporation by reference. In accordance with requirements of 1 CFR 51.5, the EPA is finalizing the incorporation by reference of the SJVUAPCD rule described in the amendments to 40 CFR part 52 set forth below.
