(a) What are the
Board's minimum recycled plastic postconsumer material quality standards for
regulated trash bags? The following recycled postconsumer plastic material
quality standards have been developed by the Board for regulated trash bags.
The Board will make available the quality standards by December 31 of each year
and they will apply for a maximum of two years. The test methods to be used by
the Board to determine whether the standards are being met are included with
each characteristic, whenever applicable. These minimum specifications are for
the plastic RPPCM blended with a minimum of thirty percent (30%) APCM.
| (1) |
Moisture: |
750 parts per million
(ppm) maximum. |
|
|
Test Method: |
ASTM D-4019-88 or
equivalent method. |
| (2) |
Contamination: |
A specification
mutually agreed upon by the trash bag manufacturer and supplier of RPPCM. |
|
|
Test Method: |
A test method mutually
agreed upon by the trash bag manufacturer and supplier of RPPCM. |
| (3) |
Pellet uniformity: |
The total
number of pellets in a one gram sample must not vary more than ten percent (+/-
10%) from the average number for five samples. |
|
|
Test Method: |
A simple count. |
| (4) |
Specific gravity: |
Resin must be
within one percent (+/- 1%) of a specific gravity mutually agreed upon by the
trash bag manufacturer and resin manufacturer. |
|
|
Test method: |
ASTM D-792-91, ASTM
D-1505-90 or equivalent. |
| (5) |
Melt Index: |
HDPE base resin -
0.25-0.85 |
|
|
|
LDPE base resin - 0.25-2.5 |
|
|
|
LLDPE base resin - 0.5-2.5, and
the melt index must not vary by more than fifteen percent (+/- 15%) within a
shipment, and it must be within thirty percent (+/- 30%) from shipment to
shipment over the length of the contract. |
|
|
Test method: |
ASTM D-1238-88, or
equivalent. |
The ASTM test methods D-4019-88: Standard Test Method for
Moisture in Plastics By Coulometry, D-792-91: Standard Test Methods for Density
and Specific Gravity (Relative Density) of Plastics By Displacement, D-1505-90:
Standard Test methods for Density of Plastics by the Density-Gradient
Technique, D-1238-88: Standard Test methods for Flow Rates of Thermoplastics by
Extrusion Plastometer are incorporated herein by reference.
(b) Where can I find the ASTM test methods?
You can find ASTM test methods in the annually updated book called Annual Book
of ASTM Standards, (ASTM) Section 8, Volume 08.01, published by the American
Society for Testing and Materials, 1919 Race Street, Philadelphia, PA
19103-1187, the noted sections of which are herein incorporated by reference.
All ASTM tests must be performed with the most recently approved methods. The
non-ASTM test methods have yet to be standardized or are
self-evident.
(c) What if a mutually
agreeable specification cannot be reached between buyer and seller of the
RPPCM? If a mutually agreed upon specification cannot be reached in good faith,
the trash bag manufacturer must purchase and use RPPCM which meets any past or
present specification for RPPCM that the manufacturer has previously used to
purchase material.
(d) What if an
equivalent test method is mutually agreed upon between buyer and seller of
RPPCM and the RPPCM for sale does not pass the test? As long as the equivalent
test method was mutually agreed upon by buyer and seller, an exemption claim
based upon the failure to purchase the material will be accepted and evaluated
by Board staff. If, however, an equivalent lest method is not agreed upon, or
problems arise with the test method after an agreement is reached, a trash bag
manufacturer may not make a certification pursuant to Section
17981 based on the failure to
purchase the material for which the test method was inadequate.
(e) What if a trash bag manufacturer produces
its own RPPCM? If a trash bag manufacturer produces enough RPPCM to meet the
RPPCM use requirement, the manufacturer may not claim an exemption. If,
however, the manufacturer can produce only a portion of the RPPCM it needs to
comply with the requirements of this program, the manufacturer may file a
request for a exemption if the failure to meet the use requirement was due to
the quality or availability of the RPPCM offered for sale.
(f) I wish to certify that I was not able to
meet the regulatory requirements because the RPPCM available to me did not meet
the Board's quality standards. What must I do to make this certification? For
each shipment or sample of RPPCM you rejected or refused to purchase on the
basis that it did not meet the Board's minimum RPPCM quality standards, it is
your responsibility to document your claim. Required documentation includes all
of the following, but is not solely limited to these items:
(1) The list of the suppliers of RPPCM with
whom you had purchase discussions after you realized that you might not meet
the regulatory requirements,
(2)
Any and all specifications and test methods which were mutually agreed upon
between you and your RPPCM suppliers,
(3) Independent test results, product
specifications, a letter of certification, or other documentation from each
supplier of RPPCM you rejected or refused to purchase on the basis that it did
not meet the Board's minimum RPPCM quality standards, demonstrating that the
material does not meet the quality standards,
(4) Performance of ASTM tests, identified in
Section
17982(a) of this
Article, may be conducted by the Board to assist you in substantiating your
claim. If testing is to be done, the Board shall inform you of proper shipping
and handling procedures for samples based on the provisions of the particular
test to be used,
(5) A written
explanation describing the circumstances leading to your decision to reject or
refuse to purchase every sample or shipment of rejected or refused RPPCM,
and,
(6) A written explanation from
the supplier of any sample or shipment of RPPCM describing the quality of the
particular material which was rejected or refused by you.
(g) Will the Board periodically review its
RPPCM quality standards? Yes, the Board will review its RPPCM quality standards
whenever the Board determines it is necessary. The standards will be reviewed
at least once every two years until the year 2000.
