In Maine, the governing authority
on the beneficial use of materials is the Maine Department of Environmental
Protection. Chapter 418 of the DEP's Maine Solid Waste Management Rules is
devoted solely to the beneficial use of non-hazardous solid waste.
Chapter 418 lists a number of specifications for beneficial
reuse, some of which apply to boiler ash, fly ash, cement kiln dust, lime mud,
metal waste, and dredged spoil. In general, when a material is beneficially
reused, it can't pollute the air or water or pose a health hazard. Also, a
project for beneficial reuse can't be located within a protected natural
resource, and soil from a project can't be allowed to flow into a protected
area.
When a material is beneficially reused in construction
projects, it must meet the requirements given in the Maine Erosion and Sediment
Control Handbook for Construction: Best Management Practices (Cumberland County
Soil and Water Conservation District/Department of Environmental Projection,
March 1991) or an equivalent publication.
The DEP's approval for the beneficial use of a material isn't
necessarily approval for the project utilizing the material. Federal, state, and
local requirements must be met for a project to be licensed.
Beneficial use isn't considered a form of disposal, and any
kind of landfill or other disposal site is subject to
Chapter 401 of the Maine
Solid Waste Management Rules.
When a beneficial use procedure includes storing the material
for longer than 90 days, the regulations of
Chapter 402 must be taken into
account.
When processing is required for the beneficial use of a
material, the material is subject to
Chapter 409 regulations.
When a material is to be beneficially used for agricultural
purposes, it is subject to
Chapter
419.
A number of
Chapter 400 requirements must be met as well when
any material is beneficially reused. Section 3.D (1-10) of Chapter 418 lists the
Chapter 400 requirements that apply to beneficial reuse. They include
regulations dealing with financial ability, traffic, air quality, and variances,
among other issues.
Within Chapter 418, there are also sections that deal with
reduced procedures for specific materials and uses. Section seven of the
document details requirements for the materials that don't qualify for reduced
procedures. Below are links to information from Chapter 418 for each material in
this study.
