Universal Citation: UT Admin Code R 315-312-3
Current through Bulletin 2024-06, March 15, 2024
(1) No new composting facility shall be located in the following areas:
(a) wetlands, watercourses, or floodplains;
or
(b) within 500 feet of any
permanent residence, school, hospital, institution, office building,
restaurant, or church.
(2) Each new compost facility shall meet the requirements of Subsection R315-302-1(2)(f)
(3) Each owner or operator of a composting facility, in addition to the operational plan required in Subsection R315-312-2(1), shall develop, keep on file, and abide by a plan that addresses:
(a) detailed plans and specifications for the
entire composting facility including manufacturer's performance data for
equipment;
(b) methods of
measuring, grinding or shredding, mixing, and proportioning input
materials;
(c) a description and
location of temperature and other types of monitoring equipment and the
frequency of monitoring;
(d) a
description of any additive material, including its origin, quantity, quality,
and frequency of use;
(e) special
precautions or procedures for operation during wind, heavy rain, snow, and
freezing conditions;
(f) estimated
composting time duration, which is the time period from initiation of the
composting process to completion;
(g) for windrow systems, the windrow
construction, including width, length, and height;
(h) the method of aeration, including turning
frequency or mechanical aeration equipment and aeration capacity; and
(i) a description of the ultimate use for the
finished compost, the method for removal from the site, and a plan for the
disposal of the finished compost that can not be used in the expected manner
due to poor quality or change in market conditions.
(4) Composting Facility Operation Requirements.
(a) Operational records must be
maintained during the life of the facility and during the post- closure care
period, which include, at a minimum, temperature data and quantity and types of
material processed.
(b) All waste
materials collected for the purpose of processing must be processed within two
years or as provided in the plan of operation.
(c) All materials not destined for processing
must be properly disposed.
(d)
Turning frequency of the compost must be sufficient to maintain aerobic
conditions and to produce a compost product in the desired time
frame.
(e) During the composting
process, the compost must:
(i) maintain a
temperature between 104 and 149 degrees Fahrenheit (40 and 65 degrees Celsius)
for a period of not less than five days; and
(ii) reach a temperature of not less than 131
degrees F (55 degrees C) for a consecutive period of not less than four hours
during the five day period.
(f) The following wastes may not be accepted
for composting:
(i) asbestos waste;
(ii) Hazardous waste;
(iii) waste containing PCBs; or
(iv) treated wood.
(g) Any composting facility utilizing
municipal solid waste, municipal sewage treatment sludge, water treatment
sludge, or septage shall require the generator to characterize the material and
certify that any material used is nonhazardous, contains no PCB's, and contains
no treated wood.
(h) If the
composting operation will be utilizing domestic sewage sludge, septage, or
municipal solid waste:
(i) compost piles or
windrows shall be placed upon a surface such as sealed concrete, asphalt, clay,
or an artificial liner underlying the pile or windrow, to prevent contamination
of subsurface soil, ground water, or both and to allow collection of run-off
and leachate. The liner shall be of sufficient thickness and strength to
withstand stresses imposed by compost handling vehicles and the compost
itself;
(ii) run-off systems shall
be designed, installed and maintained to control and collect the run-off from a
25-year storm event;
(iii) the
collected leachate shall be treated in a manner approved by the Director;
and
(iv) run-on prevention systems
shall be designed, constructed, and maintained to divert the maximum flow from
a 25-year storm event.
(i) If the Director determines that a
composting operation, which composts materials other than domestic sewage
sludge, septage, or municipal solid waste, is likely to produce a leachate that
in combination with the hydrologic, geologic, and climatic factors of the site
will present a threat to human health or the environment, the Director may
require the owner or operator of the composting facility to meet the
requirements specified in Subsection R315-312-3(4)(h).
(j) The finished compost must contain no
sharp inorganic objects and must be sufficiently stable that it can be stored
or applied to land without creating a nuisance, environmental threat, or a
hazard to health.
(5) Composting Facility Closure and Post-closure Requirements.
(a) Within 30 days of closure, a composting
facility shall:
(i) remove all piles,
windrows, and any other compost material on the composting facility's
property;
(ii) remove or revegetate
compacted compost material that may be left on the land;
(iii) drain ponds or leachate collection
system if any, back-fill, and assure removed contents are properly
disposed;
(iv) cover if necessary;
and
(v) record with the county
recorder as part of the record of title, a plat and statement of fact that the
property has been used as a composting facility.
(b) The post-closure care and monitoring
shall be for five years and shall consist of:
(i) the maintenance of any monitoring
equipment and sampling and testing schedules as required by the Director;
and
(ii) inspection and maintenance
of any cover material.
