Attachment 2
Staff Response to Comments from the Polystyrene Packaging Council
(PSPC) on the Proposed Ordinance Banning Non-Recyclable Plastic Disposable Food
Service Containers
PSPC’s comments suggest that “significant adverse environmental impacts” will result from City Council’s
adoption of this ordinance. This conclusion is based on the erroneous
assumption that implementation of the ordinance will result in a significant
increase in the use of one material - biodegradable plastic - and a related
increase in the amount of biodegradable plastics in the litter stream. This is addressed in the response to Comment 3
below and it makes all of PSPC’s other arguments irrelevant, since they are
premised on this erroneous assumption. However,
for the sake of completeness, staff has addressed all of the PSPC’s comments. As detailed herein these arguments are demonstrably
false with respect to
The ordinance specifically prohibits the use of
non-recyclable plastic by food providers in
PSPC’s Comments 4 through 12 claim that increasing the amount of biodegradable plastic in the litter stream will have adverse environmental consequences. These comments are based on several flawed arguments which are discussed in detail below. It should be noted that biodegradable plastics have been strongly advocated as a replacement for expanded polystyrene and non-recyclable plastic food packaging by the Santa Monica Task Force on the Environment and the non-profit environmental group Heal the Bay because of the environmental benefits they provide with respect to the products they would replace. Members of the Task Force on the Environment include experts in the areas of environmental science, toxicology, air quality, ocean water quality, and greenhouse gas emissions. Heal the Bay’s staff includes several scientists with significant expertise in environmental science, coastal ecosystems and ocean water quality.
Comments 1 and 2: Proposed Ordinance Is Subject to CEQA
and Trash TMDL
For the reasons detailed in the staff report and herein the City has determined that this ordinance is exempt from the provisions of the California Environmental Quality Act (CEQA) pursuant to Sections 15061 (b)(3) and 15308 (Class 8) of the CEQA guidelines.
Comment 3: Reasonably Foreseeable Increase in Use of
Bio-Plastics
The assumption expressed by the PSPC in this comment - that
the use of biodegradable plastic will significantly increase in
The ordinance does not specify what alternative product(s) a
food provider must use. Under the requirements of the ordinance a food provider
in
Since biodegradable plastic containers are more expensive than other plastic and non-plastic alternatives it is likely that few, if any, vendors will switch to these products given the cost differential, particularly in light of the wide availability of other less expensive alternative products. The increased cost of biodegradable plastic products was the primary complaint expressed in written communication that the City received in April and May 2006 from the California Restaurant Association. This complaint was also voiced by various local restaurant owners at the City Council meeting on June 13, 2006, and has been expressed to city staff by restaurant owners and representatives of grocery stores in many previous and subsequent meetings.
Furthermore, in a letter sent to the City on April 19, 2006 from the PSPC, the American Chemical Council (ACC) and the Food Service and Packaging Institute (FSPI), these groups state that “Bio-based alternatives are perceived as being commonly available, but the experience of business owners who have been forced to switch materials has been contrary to this. In addition, because these products are degradable and prone to break down when exposed to heat and moisture, stockpiling large quantities for prolonged periods can result in inventory being ruined.” This statement seems to directly contradict the assumption by the PSPC that the ban would increase the use of bio-plastics among food service providers.
The other assumption expressed by PSPC in this comment - that “the ban can be expected to increase the amount of PLA and other bio-plastics in the litter stream, on beaches and the marine environment” - is also erroneous because 1) as noted above it is not likely that the usage of these type of products will increase by a significant amount; and 2) due to the physical properties of bio-plastics it is less likely that they will enter the litter stream or the environment. This is because a) biodegradable plastics can be composted or recycled, so it is expected that a portion of the products that are used will be composted or recycled[1] and b) due to the higher weight of these products (compared to EPS) and their ability to biodegrade in the environment, it is less likely that those products that are disposed of, either properly or improperly, will be transmitted to the beach and marine environment by wind or water, as compared to EPS or other non-recyclable plastic.
The percentage of solid waste diverted from the landfill

In short, based on the factors described above, the City
anticipates a very minimal increase in the use of PLA’s and other
bio-plastics. Moreover, to the extent that these products are used, given
the City’s substantial track record in recycling and composting, and the
physical composition of these products, they will not find their way to beaches
and the marine environment in any appreciable amount. PSPC’s entire
premise is faulty and is wholly divorced from the
Comment 4: Air Quality Impacts
The arguments presented in this comment are erroneous for a
number of reasons, foremost of which is because they are predicated upon an
increase in the use of biodegradable plastic products in
In this comment PSPC states that “Evidence suggests that bio-plastics such as PLA, when introduced into
the litter stream in
PSPC’s Comment 4 also alleges significant impacts from the degradation of biodegradable plastics in landfills. This directly contradicts statements made in the April 19, 2006 letter from the PSPC, ACC and FSPI referenced above, which states “In most cases, food service packaging products thought to be or marketed as biodegradable only degrade under very limited and specific conditions found in industrial composting facilities. These are not the same conditions found in landfills (emphasis added)”.
However, even if it were the case that biodegradable
plastics were to increase in landfills by a significant amount as a result of
this ordinance, and if they were able to degrade once in the landfills,
this argument would still be incorrect because 1) the majority of landfills in
the Southern California region, including those that receive waste from Santa
Monica, are covered and the methane generated by the decomposition of waste in
the landfills is collected for reuse in electricity generation, which negates
any environmental impact that the PSPC is claiming will occur; and, more
importantly 2) biodegradable plastics are plant based materials made from corn
starch. The greenhouse gas emissions
given off by these products as they degrade are equivalent to the amount of
emissions removed from the atmosphere by the corn plants as they grow, so the
net balance in emissions is zero. For
this reason alone it is not credible to claim that the degradation of
biodegradable plastics used in
In this comment the PSPC also notes that “life cycle analyses suggest that replacing polystyrene food packaging with bio-plastics will increase GHG and other pollutants required to produce an equivalent amount of bio-plastic food packaging”. While this point is not relevant for the reasons expressed in the response to Comment 3, it must also be pointed out that life cycle assessments[2] are far from conclusive on the overall environmental impacts of the manufacture and use of both bio-based plastics and non-recyclable plastics like polystyrene. The lack of conclusiveness of lifecycle assessments of packaging products is discussed in Use and Disposal of Polystyrene in California: A Report to the California Legislature, dated December 2004 by the California Integrated Waste Management Board. In addition, one of the references cited by the PSPC (Comstock et al. 2004) in support of their comments also notes this lack of conclusiveness. That report also includes a comparison of life cycle assessments from different sources in which petroleum based plastics (like polystyrene) are compared to bio-plastics on the basis of cost, non-renewable energy consumption, and greenhouse gas emissions. The report notes that “it can be seen in almost every case that bio-based plastics require less fossil fuel than the petrochemical polymers.” Thus PSPC’s own report directly contradicts PSPC’s assertion.

This comment also asserts that a “foreseeable adverse consequence to animal life stems from the risk
that increasing the amount of bio-plastics in the local environment could lead certain species to adopt these
bio-plastics as a food source.” This
is a curious statement because it is well documented that EPS and non-recyclable

Comment 11: Impacts to Composting Services
The City has been composting bio-plastics through its Zero
Waste Farmers Market program since April 2006 and has not encountered any
concern from industrial composting facilities with regard to “contamination’ of
the compost. Based on the references
cited by PSPC, the argument made in this comment seems to stem from commercial
conditions in
Comment 12: Impacts to Human Health
The ordinance does not require food providers to conduct in-store collection and separation of food service containers, so this point has no relevance to the adoption of the ordinance.
Comment 13: Impacts of Increased Litter
As noted above, this ordinance will not lead to an increase in the use of bio-plastics in the community and therefore will not increase the amount of bio-plastics in the litter stream (See response to Comment 3, paragraph 5 on page 2-3 of this document). Also, with regard to the statement that “A significant potential impact of biodegradable plastics is simply the physical increase in litter, resulting from the behavior of the public which perceives biodegradables to be products that ‘go away’ quickly in the environment” the PSPC has not presented any scientific evidence that supports this opinion. Although the statement is drawn from an “expert” report prepared by a toxicologist (as opposed to a sociologist or other researcher who studies human behavior), it is entirely based on conjecture and speculation.
