Memorandum March 25, 2025 Page 7 21202-23 North County Landfill_AQ_0307 Valley Air District has implemented these plans and adopted nearly 650 rules that have resulted in significant emissions reductions. Specific rules applicable to the proposed project include the following: • Rule 2201 (New and Modified Stationary Source Review Rule). This rule, also known as New Source Review, applies to all new stationary sources and all modifications to existing stationary sources which are subject to the Valley Air District permit requirements and after construction emit or may emit one or more regulated pollutant (e.g. criteria air pollutants and precursors). This rule requires new and modified stationary sources to mitigate emissions using Best Available Control Technology and to offset emissions when estimated emissions are above specified thresholds. Valley Air District implementation of New Source Review ensures that there is no net increase in emissions above specified thresholds from new and modified Stationary Sources for all nonattainment pollutants and their precursors. • Rule 4102 (Nuisance). This rule prohibits discharge of air contaminants or other materials which cause injury, detriment, nuisance or annoyance to any considerable number of persons or to the public or which endanger the comfort, repose, health or safety of any such person or the public or which cause or have a natural tendency to cause injury or damage to business or property. • Rule 4642 (Solid Waste Disposal Sites). This rule limits volatile organic compound emissions from solid waste disposal sites. • Regulation VIII (Fugitive PM10 Prohibitions). This regulation consists of a series of rules requiring the implementation of dust control measures to reduce fugitive dust emissions generated by human activity. Consistent with CEQA Guideline Appendix G, the Valley Air District has adopted thresholds of significance to assist lead agencies in the evaluation and mitigation of air quality impacts under CEQA (CEQA Guidance).4 The District’s thresholds establish levels at which emissions of ozone precursors (ROG and NOx), PM10, PM2.5, carbon monoxide, sulfur oxides (SOx), TACs, and odors could cause significant air quality impacts. The Valley Air District’s thresholds of significance that are used in this analysis are summarized in Table 1 below. 4 Joaquin Valley Air Pollution Control District (Valley Air District), 2015.
