New, relocating or expanding businesses which are connected or planning to connect to the Frederick County sewer system are required under the Frederick County’s Industrial Wastewater Pretreatment Ordinance to provide specific information by completing an Industrial Waste Survey.
Commercial sewer users with only hand washing and toilet facilities need to complete Section I and II of the Industrial Waste Survey and sign the Certification Statement. Sections II through VII may not apply to all applicants and should be completed only if so directed.
Any commercial sewer user discharging wastewater other than hand washing and toilet flushing may need to submit the following documents in addition to the Industrial Waste Survey:
Additional information concerning the Industrial Pretreatment Program can be found in the Pretreatment FAQ.
Amalgam contains mercury. Mercury is a potent neurotoxin that bioaccumulates in fish and shellfish and ultimately affects human health and the environment.
The United States Environmental Protection Agency (USEPA) has set a national standard that will reduce the discharge of mercury containing dental amalgam from dental practices to sewer plants. The standard includes mandatory use of amalgam separators or similar devices, and Best Management Practices (BMP's) endorsed by the American Dental Association (ADA).
Depending on your specific practice, different requirements and deadlines must be achieved.
See what requirements pertain to your dental practice.

What Is Cross-Connection and Backflow?
Water systems depend on water pressure to keep water flowing in the proper direction through the pipes. A cross-connection is any physical connection between a possible source of contamination and the public water system. Additionally, a drop in water pressure can create a reverse flow from a property owner’s plumbing system back into the public water system. This is called backflow.
What are the Applicable Laws and Regulations?
Frederick County Water and Sewer Rules and Regulations (Section 8A), and the Frederick County Plumbing Code

Do not pour grease, fats, and oils from cooking down the drain.
Garbage disposals do nothing to protect your drain lines from accumulating grease.

In 1995, the Division of Water and Sewer Utilities' Department of Regulatory Compliance began to collect water quality samples from Lake Linganore for use in making water treatment plant operational decisions and to assist with proactively identifying potential issues with the sanitary sewer lines that surround the lake.
Since 2009, the County’s Lake Linganore Water Treatment Plant has been idle and is currently only to be used in an emergency backup capacity. However, the City of Frederick currently uses Linganore Creek as a water supply. The stored volume of water behind the dam in Lake Linganore provides limited reserve capacity for their needs.
Samples are collected from 6 sites around the lake. Sample locations can be viewed on the online map.
The beaches were chosen as sample locations solely because of their ease of access to the lake. (Note: The Division of Water and Sewer Utilities does not have regulatory authority to monitor bathing beaches.)
Information related to the Division of Water and Sewer Utilities' monitoring efforts is found below:

The Department of Regulatory Compliance, as a part the Division of Water and Sewer Utilities (DWSU):
Plans and coordinates the enforcement of state and local regulations regarding the compliance, monitoring and prevention of contamination and pollution of the public water supply and environment.
The Environmental Laboratory is a Maryland State-certified water quality laboratory. The laboratory supports operations staff by performing over 20,000 analyses used for both compliance and process control.
The Pretreatment Program provides for the regulation of wastewater discharges into the sanitary sewer system. The department administers the program in accordance with the Frederick County Industrial Waste Ordinance 12-33-628. The purpose of the program is to prevent the introduction of pollutants into the wastewater collection and treatment system. This is important to prevent interference with the treatment process, avoid damage to the equipment, or harm to workers, the public and the environment.
The Department also handles liquid waste disposal permits.
