(1) Legislative declaration. The general assembly hereby: (a) Finds that: (I) Air toxics are pollutants that cause or may cause cancer or other serious health effects, such as adverse reproductive effects or birth defects, or adverse environmental and ecological effects; and (II) Disproportionately impacted communities often include low-income neighborhoods and residents who identify as Black, Indigenous, Latino, and people of color and are disproportionately affected by air toxics emissions; (b) Determines that: (I) Colorado communities have a right to know about exposures to air toxics in real time; (II) Colorado communities are increasingly concerned about the potential health impacts of air toxics resulting from routine facility operations, fugitive leaks, upset conditions, or emergency situations; (III) Real-time air monitoring, including fenceline and community-based monitoring systems, can provide valuable air quality data to assess the potential impacts of air toxics emissions in nearby communities, to understand temporal variations in air toxics emissions, and to advise facilities of significant changes in air toxics emissions; (IV) Community-based monitoring is useful for estimating air toxics exposures and health risks and in determining trends in air pollutant levels over time; and (V) Fenceline monitoring is useful for detecting or estimating leaks, the quantity of fugitive emissions, and other air emissions from a certain facility; and (c) Declares that facilities that emit air toxics have a responsibility to collect real-time air toxics data and to provide monitoring results as quickly as possible in a publicly accessible format to help communities understand their level of exposure. (2) Definitions.

(II) Upon receipt of a revised plan, the division shall promptly post the revised plan on the division's website. If the initial plan failed to include the required elements under subsection (5)(b) of this section, the division shall again comply with subsection (5)(c) of this section with respect to the revised plan, in which case the deadline in subsection (5)(e) of this section is extended for ninety days. (e) If the division determines that the covered facility is emitting hazardous air pollutants in quantities that may pose a risk to public health in the relevant area, the division may require as part of the plan the reporting of pollutants other than covered air toxics that the monitors are reasonably capable of measuring. The division shall approve or disapprove a fenceline monitoring plan no later than eight months after it is initially submitted to the division. If the division disapproves of a monitoring plan, it shall promptly modify the monitoring plan to ensure compliance with subsection (5)(b) of this section prior to approval. (f) Once the division approves a fenceline monitoring plan, the division shall promptly post the plan on its website. Within three weeks after approval, the covered facility shall make the approved plan available to the division and the public in the relevant languages, and the division shall promptly post the translated plan on the division's website. The covered facility shall make hard copies of the approved and translated plans available at any public libraries in the relevant area. (g) If a covered facility is a major source, as that term is defined in section 25-7-114 (3), the division shall incorporate fenceline monitoring requirements into the covered facility's operating permit required by section 25-7-114.3. (h) Each covered facility shall collect real-time data from the fenceline monitoring system, shall maintain records of the data, and shall disseminate the data to the division and the public. The dissemination must: (I) Be available in real time on a website maintained by the covered facility and include a map of all fenceline monitoring equipment locations and the ability to access historical fenceline monitoring data; (II) Be in the relevant languages spoken in the relevant area; (III) Include descriptions in the relevant languages of covered air toxics and their possible health effects as specified by the federal centers for disease control and prevention; and (IV) Include data about air concentrations of any hazardous air pollutant other than covered air toxics that the division determined under subsection (5)(e) of this section must be included in the fenceline monitoring plan. (i) A covered facility shall update and resubmit for division approval its fenceline monitoring plan every five years; except that the division may require an updated plan before the expiration of five years based on: (I) Its own determination that there has been a substantial change in the covered facility's operations or emissions; or (II) A written request submitted by a member of the public that the division determines justifies an updated plan. (6) Community-based monitoring. (a) Beginning no later than January 1, 2023, the division shall conduct community-based monitoring of covered air toxics in the relevant areas. The community-based monitoring must occur for no less than thirty cumulative days during each quarter of every year.

(d) The division shall make community-based monitoring data available to the public. (7) Costs paid by covered facilities. (a) Each covered facility is responsible for the cost of installing, operating, and maintaining all fenceline monitoring equipment used pursuant to the monitoring plan as well as the cost of disseminating the data to the public. (b) A covered facility shall pay a processing fee pursuant to section 25-7-114.7 (2)(a)(III) to cover the division's indirect and direct costs of reviewing and approving fenceline monitoring plans. (c) Covered facilities shall pay the division for the covered facility's annual pro rata share of the direct and indirect costs of conducting community-based monitoring, which money shall be credited to the stationary sources control fund created in section 25-7-114.7 (2)(b)(I). Payment will be received in advance of performing community-based monitoring unless the division expressly authorizes reimbursement.
