with Section

(1) Section
20680. Daily Cover
(2) Section
20690. Alternative Daily
Cover
(3) Section
20695. Cover Performance
Standards
(4) Section
20700. Intermediate
Cover
(b) Additional
Operating Requirements for Waste Tire Monofills. In addition to the
requirements set forth in (a) above, all waste tire monofills shall adhere to
the following waste tire monofill standards:
(1) Waste tire monofill facilities shall
comply with Title 14, California Code of Regulations, Division 7, Chapter 3,
Article 5.5 and with Title 14, California Code of Regulations, Division 7,
Chapter 6, Article 8.5.
(2) Waste
tires disposed in a waste tire monofill shall be altered waste tires or shall
be otherwise permanently reduced in volume prior to disposal in a manner
approved by the EA and the Board on a case-by-case basis. Waste tires disposed
in a tire monofill shall also comply with the following specifications, unless
alternative specifications are approved pursuant to subsection (b)(10):
(A) Tire pieces passing a 3 inch (76 mm)
square mesh sieve shall be limited to a maximum of 50% by weight and tire
pieces passing a 1.5 inch (38 mm) square mesh sieve shall be limited to a
maximum of 25% by weight in the waste tire monofill to limit the potential for
internal heating.
(B) The waste
tire monofill shall contain less than 1% by weight of tire particles small
enough to pass through a no. 4 (4.75 mm) sieve.
(C) The waste tire monofill shall contain no
more than 5% altered tires having metal fragments that protrude more than 2
inches (51 mm) from the cut edges.
(D) Disposal of any material other than waste
tires and cover is prohibited.
(E)
Disposal of the remains of tires that have been subjected to fire shall be
prohibited.
(F) Disposal of
factory-reject tire carcasses that have been only partially vulcanized shall be
prohibited.
(G) Disposal of rubber
fines shall be restricted to a separate area of the monofill as a discrete cell
that is isolated from altered waste tire fill cells and mixed completely with
an equal volume of cover during the filling operations.
(H) In the top 12-inch layer of altered waste
tires, a minimum of 90 percent (by weight) of the altered waste tires shall
have a maximum dimension, measured in any direction, of 12 inches (305 mm) and
100 percent of the altered waste tires shall have a maximum dimension, measured
in any direction, of 18 inches (457 mm).
(3) Representative samples of altered waste
tires to be disposed in a waste tire monofill shall be collected and analyzed
for gradation and protruding wire on a monthly basis, or less frequently if
approved by the EA and the Board, to ensure compliance with subsections
17346.3(b)(2)(A), (B), and
(C). Representative samples of cover to be
disposed or utilized at a waste tire monofill shall be tested to ascertain
compliance with the limitation on organic matter set forth in subsection
17346.3(b)(5) of
this Article 5.4. Records of the results of these samples shall be maintained
in the records required by Section
17346.4 of this Article
5.4.
(4) The last lift of altered
waste tires disposed in a waste tire monofill shall be compacted to provide a
flat and stable surface.
(5) Waste
tire monofill cells shall not exceed a maximum depth of 20 feet (6 m), and a
maximum cell area of 12,500 square feet (1161 square meters). A minimum
distance of 2 feet shall be maintained between tire shreds in adjacent cells.
Intermediate cover shall be placed to wholly encapsulate each monofill cell.
Intermediate cover shall consist of soil with less than 5% organic matter as
determined by a loss on ignition test (ASTM D 2974-00) and compacted to the
maximum density obtainable at optimum moisture content, plus or minus 3
percent, to obtain a stable surface, using methods that are in accordance with
accepted engineering practice.
(6)
The active face of not more than two (2) cells shall be uncovered at any given
time within a waste tire monofill facility.
(7) A minimum of 6 inches (152 mm) of cover
shall be placed over the entire working face at the end of each operating day
if:
(A) the working face is to remain open
and inactive for longer than 24 hours; or
(B) when there is precipitation. The cover
shall consist of the same material used as intermediate
cover.
(8) If more than
one waste tire monofill cell is stacked vertically, temperature sensors shall
be installed within the underlying cells to monitor cell temperatures. The
operator shall submit a plan that sets forth the location and frequency of
sensor placement for approval by the EA and the CIWMB. In addition, a fire
prevention plan shall be in place to address any zones, which experience
sustained elevated temperatures to reduce temperatures to safe levels. Both
plans shall be made part of the Fire Prevention, Control and Mitigation Plan,
which is defined in Section
17346.5(b)(1).
Records of these results of elevated temperature shall be maintained in the
records required by Section
17346.4 of this Article
5.4.
(9) An adequate stockpile of
cover and equipment, as required and approved by the EA and the Board, shall be
available in the event of fire to insure a cover of a minimum depth of 3 feet
on all waste tires, crumb rubber and rubber fines at the waste tire monofill
facility exposed to the atmosphere.
(10) The operator may propose to the EA and
the Board alternative operating criteria to those specified in subsections
17346.3(b)(2) through
(b)(9) together with information supporting
the proposal. The EA and the Board may approve such alternative criteria only
if the EA and the Board determine that the alternative criteria protect the
public health and safety and the environment at least as effectively as the
criteria specified in subsections
17346.3(b)(2) through
(b)(9).
(11) Any mining or excavation of waste tires
from a waste tire monofill shall be in accordance with a site-specific
excavation and materials management plan approved by the EA and the
Board.
(12) For the purposes of
this Article, in addition to the requirements of Title 27, California Code of
Regulations, Section
20610 (Training), site personnel
shall be trained in fire safety, prevention and
suppression.
