NOx is the most demanded offset pollutant in California — it drives ozone formation, and New Source Review permits in ozone nonattainment areas (San Joaquin Valley and South Coast are classified Extreme; Sacramento Metro is Serious) carry binding NOx offset requirements at ratios up to 1.5-to-1.
ERCs are district-bound: a NOx credit banked in South Coast AQMD is usable in South Coast AQMD (or its air basin with district board approval). Tell us the tonnage your permit requires and we contact the holders above, confirm what is available, and can represent you as buyer's broker — no fee to inquire.
