To that end, EPA develops regulations, guidance and policies that ensure the safe management and cleanup of solid and hazardous waste, and programs that encourage source reduction and beneficial reuse. The alleged violations were identified during a April 17-24 2018 inspection by EPA. Allegations in the settlement include: (1) failure to comply with Method 21 air monitoring requirements; and (2) failure to prevent open ended lines or valves in equipment used in light liquid service as required by COMAR. Per the terms of the Consent Agreement, Respondent will pay a civil penalty in the amount of $72,243.00.
