IL HB2562

Requires wireless providers seeking permits to collocate small wireless facilities to submit additional documentation including a radio frequency engineer affidavit certifying FCC compliance, an acoustic analysis report, proof of National Environmental Policy Act review, and easement documentation demonstrating installation rights

Expands the distance within which an authority may propose alternative collocation sites from 100 feet to 200 feet of a proposed new utility pole location

Clarifies that wireless facility replacements involving changes in design, power output, frequency, bandwidth, signal strength, or location on the structure are not "substantially similar" and require standard permit applications and fees

Authorizes local authorities to adopt rules requiring providers to place above-ground small wireless equipment below ground when feasible and to replace larger facilities with smaller, less visually intrusive ones as new technology becomes available

Establishes comprehensive radio frequency compliance requirements including ongoing monitoring, quarterly or annual certification reports, testing upon authority request, and penalties of $750 per day for facilities exceeding FCC emission standards, which may be declared public nuisances
