DMCF FREQUENTLY ASKED QUESTIONS
There are a number of steps and there are several agencies involved. The USACE applied for and obtained a permit called a "Water Quality Certification" (WQC) from MDE, which is needed to use the Dredged Material Containment Facility (DMCF). MDE advised the USACE that they must ensure there will be no further degradation and that the drinking water issue is being addressed. The USACE is fulfilling those requirements by installing a liner over the site before any new placement occurs, and working with the MDOT MPA for the installation of a drinking water supply system to the affected areas.
The USACE has installed a liner that covers the entire site. They have also developed a monitoring plan to evaluate changes in groundwater in the vicinity of the site. Please click HERE for more information regarding the groundwater monitoring plan. MDE also requires discharge monitoring from the DMCF, per the requirements of the MDE WQC, which will occur during any discharge event. The specific parameters for discharge are still to be determined.
The environmental window for maintenance dredging of the Chesapeake & Delaware (C&D) Canal is from October 1st to March 31st annually. Inflow of dredged material will occur on the Elk River side of the facility approximately 0.4 miles from the Stemmers Run boat ramp and will not be visible from the communities. Dredged material is pumped in to the DMCF in a slurry as a ratio of about 80% water and 20% dredged material (silts and sands). After dredged material begins to settle to the bottom of the DMCF, the water is drained through a sluice to adjacent surface waters. Dredging may begin in fall of 2017. Dredging jobs can be completed generally in a few weeks. No dredging will occur in spring and summer months.
While heavy equipment will be needed to manage the drying process within the site, the USACE will address concerns regarding aesthetics as well as issues with the safety and security of the equipment. Landscaping around the site and mosquito control while the material in the site is wet will be part of the plan.
