Geoflex <br /> 252 Welsh Pool Read <br /> Lionville, PA 1934-1 <br /> RE: REQUEST FOR APPROVAL OF GEOFLEX 11 PIPING FOR USE IN <br /> UNDERGROUND TANK SYSTEMS <br /> Geotlex II primary can be used fir primary piping, and has U-L USA approval for this use. <br /> Geotlex iI secondary piping can he used as a secondary containment system, and has UL- <br /> t;SA approval, if the following conditions of approval can be met: <br /> Piping must be installed so that it is sloped so that all relcascs will flow to a <br /> collection sump located at the low point of the underground piping. CCR Title 23, <br /> Section 2536 (c) <br /> 2. Secersdary containment system must pass a minimum 5 psi pressure test for 30 <br /> ininutrs prior to covering piping trench. Uniform Fire Code <br /> 3. Primary and secondarf containment system must pass a percisson test upon <br /> completion of final covering including all cement work. H 3t S Code, Section 25291 <br /> (h) <br /> �. Because the piping is flexihle and may move in the back fill due to changes in <br /> pressure in the line, and because this may cause abrasion of the secondary, secondary <br /> piping must be tested every two years hydrostatically, or other approved method, if it <br /> is to be placed directly in the back fill.. If the piping is placed in the protective <br /> containment tubing provide by Environ, no additional secondary pipe testing will be <br /> required. <br /> 5 All piping installed within San Joaquin County must bear the UL-USA label approval <br /> statement shown below, which was provided by Environ for this approval. Failure to <br /> nave the proper Sabel on e<tc:h piece of pipe will be grounds for disapproval. <br /> 'Ml7:S 100 AA?W MtIMAAY♦Ill t1t 1IkCONIIAjkY MAY WORKINO FREMUAL•FOLLOW NVALLA 1 0 <br /> teL:'71UL,lOM-ojo97Dt I LlTrai)W m..lTALLuc S*CO#lM41kv=ffAD0A=(T 4iDL40 1011 r1rrX6LM)A <br /> MODVC�C,ALC13004-S 1 ALC(((M.N{XTU*e1-=UT JA-:a*' <br /> ,i owir.io.
