Home / District guides / Tuolumne County APCD
The Air Pollution Control Officer confirmed (Aug 2026) the district has no records responsive to a banked-ERC request — i.e., no banked credits on file. Verified coverage, tracked here.
Emission Reduction Credits are banked, district-certified reductions in NOx, ROG/VOC, PM10, SOx, or CO. Businesses building or expanding in the district may be required under New Source Review to purchase ERCs to offset new emissions before an air permit issues. Credits are generally usable only within Tuolumne County APCD (or its air basin with district board approval — Health & Safety Code §40709.6), which is why local scarcity sets the price. The district verifies reductions and records every transfer.
District office: (209) 533-5693.
