Editor's note— Ord. No. 354 , § 1, adopted July 24, 2019, amended Ch. 15.10 in its entirety to read as herein set out. Former ch. 15.10, §§ 15.10.010—15.10.100 was entitled "Wood Stove and Fireplace Ordinance," and derived from: Ord. 298 § 1 (part), adopted 2002; and Ord. No. 344, adopted June 8, 2016.
15.10.010 - Purpose.¶
A. This chapter shall be cited as the "Wood-Burning Device and Open Burning Ordinance."
B. This chapter is enacted for the purpose of improving the air quality within the city limits and protecting the general welfare of the citizens and residents of Portola. The EPA officially designated the Greater Portola area as federal nonattainment for the federal annual standard for PM 2.5 (particulate matter with an aerodynamic diameter of 2.5 microns or less), on April 15, 2015. High PM 2.5 levels are mostly due to impacts from residential wood-burning. The city council finds there is a need to regulate and reduce harmful emissions of exhaust gases from wood-burning heaters and fireplaces, and that an appropriate method of regulation is a wood-burning device ordinance.
(Ord. No. 359 , § 1, 9-9-2020; Ord. No. 354 , § 1, 7-24-2019)

If the disclosure report indicates that a wood-burning heater on the property within the city limits is uncertified, the wood-burning heater must be removed from the property and destroyed/recycled at an approved facility or agency. Re-inspection and a copy of documentation from the destroying/recycling facility or agency is required by the control officer prior to issuance of a certificate of compliance.

- Upon determination that mandatory curtailment is required, the Air District shall notify the public through one or more of the following methods:
a. A recorded telephone message.
b. Messages posted on the Air District website.
c. Electronic mail messages to persons or entities that have requested such notice.
d. Notifying broadcast, print or social media operating within the boundaries of the City of Portola.

B. Registration of EPA-Certified Devices.
Eligibility Requirements. Any EPA-certified wood-burning heater is eligible to be registered with the Air District.
Registration Process. Effective July 1, 2020, persons applying to register a wood-burning heater shall submit a completed application and supplemental documentation demonstrating compliance with the eligibility requirements to the district. Supplemental documentation shall include the following:
a. Receipt or invoice from the installation or purchase that includes the manufacturer and model name of the wood-burning heater, or
b. A certification from the Air District verifying that the wood-burning heater meets the eligibility requirements.

C. Penalties. Any person that violates the provisions of Section 15.10.060 is subject to the following:
First Time Violators: A notice to comply or warning will be issued. The notice to comply will require that any EPA-certified wood-burning heater be registered within thirty days.
Second Time Violators: Completion of a wood smoke awareness course that has been approved by the Air District, or payment of a penalty of fifty dollars, or submission of proof of replacement of non-certified device with an EPA-certified wood-burning heater or exclusively gaseous- or liquid-fueled heater.
Third Time Violators: Payment of a penalty of one hundred fifty dollars or submission of proof of replacement of non-certified device with an EPA-certified wood-burning heater or exclusively gaseous- or liquid-fueled heater.
Fourth Time Violators: Payment of a penalty of five hundred dollars or submission of proof of replacement of non-certified device with an EPA-certified wood-burning heater or exclusively gaseous- or liquid-fueled heater.

Reg. 3086, January 15, 2013 (the 2012 PM 2.5 annual NAAQS) by the attainment date, (2) the area has failed to meet any reasonable further progress (RFP) requirement or quantitative milestone requirement in the Portola Fine Particulate Matter (PM 2.5) Attainment Plan (as approved at 84 Fed. Reg. 11208, March 25, 2019), or (3) California has failed to submit a quantitative milestone report required under the federal Clean Air Act for the 2012 PM 2.5 annual NAAQS, all provisions of Section 15.10.060 will continue to be in effect, except for the duration of curtailment season (Section 15.10.060.A.1) and curtailment level (Section 15.10.060.A.4), which are revised as follows:
List of curtailment months in Section 15.10.060.A.1 expands to include months of January, February, March, April, September, October, November, and December.
A. Curtailment level described in Section 15.10.060.A.4 is lowered from thirty ug/m3 to twenty ug/m3.

C. Section 15.10.070 will remain in effect until the U.S. EPA either approves an attainment plan for the area that satisfies the serious area requirements for the 2012 PM 2.5 annual NAAQS or determines in writing that the RFP and/or quantitative milestone failure that triggered the implementation of this section has been corrected.
