• • Total• environrnental protection products f#' your • •ary containment needs Bulkhead Fittings _ sae -ser Sumps and Pans Guide Specifications Short Form The contractor shall provide .ne crv-oflex"` Double -Wall piping system, as manufactu-e:: =y Total Containment, Inc. Both the primary and seccn�a=+Ping systems shall be installed and integrity tes:e� cordance with the manufacturer's published ins --a!=- c -i instructions. Long Form Design: The Double -Wall Pip;n: Sys;em shall consist of a UUULC listed flexible inner P- rrary pipe contained within a ULC listed flexible outer containment pipe, each making connection within a sees of surface access containment chambers. All piai^_ runs shall be continu- ous, whereby there shall be no `stings or piping con- nections, for either the primal' or secondary contain- ment pipe which are not visile or accessible from aboveground. The secondary containment piping shall be sized to allow complete removal of the primary piping without excavation. The secondary containment system shall provide watertight containment of the tank's piping and its associated fittings, and the shear valve assembly located below each aboveground fuel dispenser unit. Product Compatibility. All the components of the Double -Wall Piping System shall be compatible with the products to be stored. Corrosion Resistance: All components of the Double - Wall Piping System shall be made of non -corrosive materials, or if metallic, such as the fittings and cou- plings, isolated from corrosion causing agents. Liquid -tight Sump/Risers Double-WallUnderg-� Z`%-896 Tanks Structural integrity: The outer secondary ment system shall be of such design and ms- '0 to have sufficient strength to withstand the n--s\.rnum underground burial loads and tested in ac,=- =n'ce with AASHTC M294. The flexible inner pnn` `' P'P- ing system shall be capable of withstand:-', quid pressure five times greater than the design&,: erat- ing pressures. Integrity Testing: The outer secondary cone_, n-^ent systems shall undergo an air pressure hold gest i3 to 5 psi) after installation and before the fins[ The flexible inner primary piping system shsli =-e sub- ject to 60 psi air pressure hold test prior to `final tack - fill. Monitoring Capability. The design of the sz.•Un nary containment system shall permit any leak in t^e pri- mary piping system to be detected by a leak resection system. Access Chambers: Surface access containment chambers shall be located at the tank containing the tank's submersible pump and under each above- ground fuel dispenser. These access charnilers shall meet the following requirements: 1. Provide product -tight tank or island connection. 2. Provide product -tight pipe and conduit exits. 3. Provide sufficient strength to keep out surrounding backfill material. 4. Made of non -corrosive, product compatible and dielectric materials.
