NORTH LIBERTY, Iowa – Custom rotational molder Centro, Inc. has received a Certificate of Conformity from the Environmental Protection Agency (EPA) for its low evaporative fuel tank solution, RotoLoPerm, which was designed to address evaporative emissions requirements by both the California Air Resources Board (CARB) and the EPA.
In addition to the Certificate of Conformity issued by the EPA, Centro Inc. also has Executive Orders from CARB for their RotoLoPerm and Liquid Nylon PA6 tanks, the company reported.
The EPA has recently signed into law new regulations for off-road and marine equipment to reduce the amount of allowable emissions. The EPA regulations will begin affecting evaporative systems for Class I engines & marine personal watercraft in 2011and Class II & marine other vessels in 2012 with an Early Conformance program option, Centro explained.
RotoLoPerm is a multi-layer process that utilizes an inner and outer layer of crosslink polyethylene with a barrier material in the middle for permeation resistance, according to the company. Crosslink polyethylene offers abrasion resistance, low temperature impact properties, moldability and overall value, it stated, but it doesn’t meet the standards unless used in concert with the barrier material. RotoLoPerm technology can utilize existing tooling and is available in natural, or pigmented crosslink polyethylene of any color, the company added.
The EPA Certificate of Conformity allows Centro Inc. to provide its patent pending RotoLoPerm fuel tanks prior to the effective regulation date of 2011 and 2012. OEMs interested in participating in EPA’s Early Conformance program can earn tank-for-tank credits by converting to low emissions applications using RotoLoPerm tanks as indicated in EPA regulations 40 CFR 1054.145(e) for Non-road spark ignition equipment and 1045.145(d) for marine equipment, the company stated. Upon implementation of the EPA regulations, RotoLoPerm will be assigned a Family Emission Limit (FEL) below the applicable standard of 2.5g/m2/day. At that time, OEMs can participate in the Averaging Banking and Trading (ABT) program and bank permeation credits, Centro stated.
