The industrial surface water discharge permit is a combined state and federal permit under the National Pollutant Discharge Elimination System (NPDES). This permit is issued for industrial facilities that discharge to State surface waters. The permit is designed to meet federal effluent guidelines when applicable and also ensure the discharge satisfies State water quality standards.
All industrial, commercial or institutional facilities that discharge wastewater (or stormwater from certain facilities) to surface waters of Maryland may need this permit. Alternatively, an industrial discharge to the municipal wastewater collection system may require a pretreatment permit.
On Decembet 21, 2015, the U.S. Environmental Protection Agency promulgated a final rule to modernize Clean Water Act reporting for municipalities, industries, and other facilities by converting to an electronic data reporting system (40 CFR 127.16). The final rule requires all National Pollution Discharge Elimination System (NPDES) regulated entities to electronically submit Discharge Monitoring Reports (DMRs) effective December 21, 2016.
Before you can submit official DMRs online using NetDMR, you must attend a training webinar, successfully complete account set-up, and submit example monitoring results electronically.
Pursuant to Section 1-202 of the Environment Article, before MDE may issue a license or permit to a business that might employ a covered employee, the business shall submit to MDE a valid workers' compensation insurance policy or binder. Businesses that are exempt from having to provide workers' compensation insurance under applicable provisions of the Labor & Employment Article may need to submit a Certificate of Compliance. General permit NOIs contain a section for reporting of required information, but applicants for individual NPDES permit should use the following form as part of their application package: MDE/WMA/PER.069
A general permit is developed and issued by the Maryland Department of the Environment to cover multiple facilities within a specific category. General permits offer a cost-effective and expeditious option for permittees to obtain coverage under NPDES and State discharge permits because a large number of facilities can be covered under a single permit. According to 40 CFR §122.28, general permits may be written to cover categories of point sources having common elements, such as: industrial storm water; facilities that involve the same or substantially similar types of operations; facilities that discharge the same types of wastewater; facilities that require the same effluent limitations or operating conditions; facilities that require the same monitoring where tiered conditions may be used for minor differences within class (e.g., size or seasonal activity); and facilities that are more appropriately regulated by a general permit.
The use of general permits allows the Department of the Environment to allocate resources in a more efficient manner and to provide more timely permit coverage. For example, a large number of facilities that have certain elements in common may be covered under a general permit without expending the time and money necessary to issue an individual permit to each of these facilities. In addition, the use of a general permit ensures consistency of permit conditions for similar facilities.
Maryland's Industrial Permitting Program authorizes the following General Discharge Permits:
