Hazardous waste

The Maryland Department of the Environment (MDE) regulates hazardous waste. Its Hazardous Waste page explains who must do what: generators, storage and disposal facilities, and transporters.

In a Phase I ESA

ASTM E1527-21 lists state records of hazardous waste facilities among its standard sources. The pages read for this page link no Maryland list of facilities, so this handbook pairs none. They do describe what generators and facilities must file, and those filings are the records a request would aim at.

• Generators. MDE says a generator must obtain an EPA identification number before shipping waste off-site, and must report to the state if it generates or processes hazardous waste. MDE's permit page says the EPA forms for site identification (Form 8700-12) and for the hazardous waste permit application (Form 8700-23) must be submitted to MDE.
• Biennial reports. MDE's page on Biennial Hazardous Waste Reports cites COMAR 26.13.03.06B. It says Maryland has more stringent requirements than EPA: Maryland requires every generator that generated 220 pounds or more of hazardous waste, or 2.2 pounds of acute waste, in any calendar month, or that accumulated that much at any time, to file the report. The page read covers the 2025 reporting year, with the report due March 1, 2026. For that year it says MDE "will be sending BR notifications before January" to facilities that meet the reporting requirements, based on a list compiled from EPA's e-Manifest database, as a courtesy, and that notifications are not required by law.
• Manifests. MDE's page on the uniform manifest says that effective June 30, 2018, Maryland would no longer require facilities to mail manifest copies to MDE, and that all copies must go to EPA. That page was written before that date. For shipments initiated on or before June 29, 2018, the page says Maryland would still require hard copies. The page does not say how to obtain a copy of a manifest from either agency.
• Storage. MDE says waste can be stored on-site for up to 90 days without a permit if managed in approved containers or tanks, that long-term disposal must take place at approved treatment, storage and disposal facilities, and that records, including manifests and reports, must be kept for at least three years.
• Facility permits. MDE's permit page links a Controlled Hazardous Substance Facilities fact sheet. This handbook did not read it.

MDE also says it produces reports summarizing hazardous waste activity each year. The word "reports" there links MDE's Biennial Hazardous Waste Reports page, which is about the reports generators file.

Where to look a site up

The pages read link no facility lookup for hazardous waste. MDE's Open MDE page links data under the heading Land and Materials on complaints, inspections, violations, enforcements, extended permits and discharge permits; the page does not say which programs each covers. To report a hazardous waste violation, MDE gives 866-633-4686. MDE's Waste Management page gives 410-537-3314 for questions.

Getting the file

MDE's Public Information Act requests page covers requests for MDE records. The hazardous waste pages read do not describe a separate route.
