District Of Columbia § 8-1307 - Inspections; analyses; right of entry; notice; posting.

For the purpose of enforcing this chapter or any rule or regulation promulgated pursuant to this chapter, the Mayor may at any reasonable time, within reasonable limits, and in a reasonable manner, upon presenting appropriate credentials to the owner, operator or agent in charge:

If the officer or employee obtains any samples prior to leaving the premises, he or she shall give to the owner, operator, or agent in charge, a receipt describing the sample obtained, and if requested, a portion of each such sample equal in volume or weight to the portion retained. If any analysis is made of such samples, a copy of the results of such analysis shall be furnished promptly to the owner, operator, or agent in charge.

When there is a threat to human health or the environment, or a release of hazardous waste into the environment, and the responsible party or address is unknown, or cannot be located, written notice shall be served by conspicuously posting the notice on the property where the threat exists or the release occurred and sending a copy to the last known address via certified mail.

When dangerous chemicals and hazardous waste on property pose an imminent threat to human health or the environment, the Mayor may post the property and restrict access. The posting shall provide the public with notice that a dangerous condition exists and shall prohibit the owner from removing or handling the waste without prior approval by the Mayor.
