 construction funded with monies from `the Federal Highway Trust Fund. Other major federal
users of seeding products arc the General Services Administration, Forest Service, Army
Corps of Engineers, and several bureaus within the Department of Interior. In addition,
Federal grant monies from the Department of Housing and Urban Development can be used
in landscaping and other soil management activities.
In the proposed CPG, EPA noted that the States of California, Illinois, Michigan,
Pennsylvania, Texas, Virginia, and Washington allow the use of paper-based hydraulic
mulch. The States of Missouri and New Hampshire commented that their specifications
permit the use of this product in one or more applications. In addition, the State of Georgia
commented that its specifications allow the use of wood-based hydraulic mulch products and
that use of paper-based hydraulic mulch products should not present a significant problem.
Based on the successful usage of paper-based hydraulic mulch by several of the states
and by Federal agencies, EPA believes that usage of this product will increase as procuring
agencies begin to obtain current information about the performance characteristics of paper-
based hydraulic mulch and begin to use the products currently available.
4. Designation
In 40 CFR 247.15(a), EPA is designating hydraulic mulch products used for
landscaping and erosion control in hydroseeding applications and as an over-spray for straw
mulch. This designation includes both paper-based hydraulic mulch and wood-based
hydraulic mulch containing recovered materials. Potential uses include reseeding and soil
stabilization during highway construction; seeding during pipeline installation, mine site
reclamation, and landfill closure; residential, institutional, and commercial landscaping;
temporary erosion control at construction sites; and seeding of athletic fields and golf
courses.
B. Yard Trimmings Compost
1. Background
In the CPG, the Agency proposed designating yard trimmings compost (see 59 FR
18877, April 20, 1994). Composting is a biological process of stabilizing organic matter
under controlled conditions into a product that is rich in humus and provides organic matter,
cation exchange and nutrients to the soil. Compost has been defined in the "Composting
Glossary" by the Compost Council, an industry trade group, as follows:
Compost is the stabilized and sanitized product of composting; compost is
largely decomposed material and is in the process of humification (curing).
Compost has little resemblance in physical form to the original material from
which it was made. Compost is a soil amendment, to improve soils. Compost
is not a complete fertilizer unless amended, although composts contain
