Other notes

Both facilities share the same hours, rules and fees, so they are listed together on this page.
Fees: the free first 50 lbs for St. Louis County residents is funded by county landfill surcharge fees. St. Louis City and Jefferson County residents rely on a grant subsidy that has run out, so they currently pay for every pound ("full pay mode") until it resumes.
Payment is by credit or debit card only, taken at your car window; no cash or checks. Stay in your car; staff unload and weigh the waste. Pack items upright in boxes or bins rather than plastic bags, and do not mix chemicals.
Reservations are made online at hhwstl.com for a morning or afternoon window; no same-day reservations. If you have more than 100 lbs, the program suggests contacting it for cheaper options.
Not accepted: explosives and ammunition, radioactive waste, smoke detectors, holiday lights, medicines and medical waste, appliances, asbestos, ballasts, construction debris, household trash, tires, electronics and TVs, unknown or helium cylinders, light fixtures, bulky items, dried-out latex paint, and any business waste. Completely dried latex paint can go in the regular trash.
