Hazardous waste collection days in Maryland
Maryland doesn't regulate household hazardous waste as hazardous waste, but the state asks you to take paint thinner, pesticides, pool chemicals, and the like to your county's program instead of the trash or a drain. Some counties take it year-round, others hold collection days. Each county's page here says where its hazardous waste goes.
