Municipal Waste Water Treatment Plant
GRIT and SCREENINGS
Disposal Requirements
October 20, 2009
This document outlines the requirements for the disposal of municipal waste water
treatment plant debris screened from untreated sewage (hereafter called “GRIT and
SCREENINGS”) at the Loudoun County Solid Waste Management Facility (LCSWMF).
These requirements are based on the facility’s permit and Virginia Department of
Environmental Quality (VDEQ) memorandum (Grit and Screenings, February 26, 2007).
The LCSWMF will only accept GRIT and SCREENINGS generated from permitted
MWWTP located within the County of Loudoun, Virginia, and only on a pre-approved
basis.
GRIT AND SCREENINGS brought to the LCSWMF for disposal must meet the following
requirements:
The GRIT AND SCREENINGS must be from a Loudoun County waste water treatment plant
and may not have left the County.
The GRIT AND SCREENINGS must be washed with clean potable water.
The GRIT AND SCREENINGS must be pre-treated by thoroughly mixing with hydrated lime at
a rate to establish a minimum pH of 10 in order to both kill pathogens and reduce odor. The
amount of lime, as well as the pH minimum may be reduced with the addition of chlorine in the
wash water and/or if the owner can confirm that the Grit and Screenings contains less than 2
million fecal coliform/gram.
The washed and lime treated GRIT AND SCREENINGS must be dewatered, contain no free
liquids, and treated samples must be able to pass the paint filter test standard for free liquids
(attached).
The GRIT AND SCREENINGS shall not be malodorous as determined by the LCSWMF scale
operator.
The GRIT and SCREENINGS shall be certified by the plant operator to be non-hazardous
according to the current State of Virginia regulations governing the management of hazardous
waste in the Commonwealth, at a minimum pH of 10 and contain no free liquids and able to
pass the paint filter test.
All requests for disposal of GRIT AND SCREENINGS at the LCSWMF must be made by
a MWWTP licensed by the Virginia Department of Health (VDH) and submit the Grit and
Screenings Quarterly Disposal Request Form to the Loudoun County Department of
General Services, Waste Management Division (703-771-5500). Submission does not
denote approval. The request will be reviewed and approval/denial will be relayed to the
applicant. Current landfill fees apply.
All loads brought to the facility will be inspected. Material that does not meet the above
requirements will be rejected. Vehicles that are not capable of having their load
inspected, such as a closed tanker or vacuum truck, are not allowed.

SUBJECT: Grit and Screenings
The Solid Waste Management Regulations establish conditions under which sludge can be
landfilled (9 VAC 20-80-250.C.16). DEQ has deemed that grit and screenings do not fall under
the definition of ‘sludge’ and therefore, the stabilization requirement for sludge does not apply to
grit and screenings from a wastewater treatment plant. However, improperly maintained or
operated grit and screening devices can produce waste that has a higher organic content that can
contribute to odors at a landfill. DEQ staff should work with both the wastewater treatment plant
and the landfill to ensure proper treatment of this material.
If odor from grit and screenings becomes an issue at a landfill, then the waste inspector should:
1. Remind the landfill that they can reject any load.
2. Work with the landfill on an odor control program, evaluating all sources of odor, and
suggesting the facility work with the wastewater treatment plant on proper
treatment/handling of the material before it comes to the landfill. When feasible, the
landfill and wastewater treatment plant should coordinate the delivery of the grit and
screenings so that the grit and screenings can be immediately covered upon its arrival at
the landfill.
3. Notify the water inspector or appropriate regional contact (for the contributing
wastewater treatment facility) of the odor issue at the landfill.
The water inspector should:
1. Schedule an inspection of the wastewater plant.
2. Inspect the headworks for proper operation and maintenance of the grit and screening
removal equipment.
a. Any non-functioning equipment, especially wash water equipment, should be
noted and the facility should be directed to repair the equipment as soon as
possible.
b. If all operations and maintenance are within accepted norms, the inspector can
suggest additional operational controls to help with odor such as lime addition,
increased frequency of disposal, manual washing of the material, and other
measures.
c. When feasible, the landfill and wastewater treatment plant should coordinate the
delivery of the grit and screenings so that the grit and screenings can be
immediately covered upon its arrival at the landfill.
3. Report back to the waste inspector as to their findings.
