The process will include cutting new access way into the USTs, clean out, abrasion blast, perform structural analysis, line the USTs per API 1631 and install new manway access lids (sump and traffic ring install provided by other contractor). The current USTs are fiberglass double-walled 12,000-gallon tanks. The owner will provide an excavation and paving company to construct 6-foot by 6-foot access ways to each tank, per instructions from CGRS. Scope of Work Prior to the start of the project, the USTs shall be empty of fuel, or as low as possible, one tank shall be made available prior to the start of the project. CGRS shall coordinate with the Utah DEQ on the installation and obtain all permits. CGRS shall provide all equipment, materials, and labor to perform three (3) internal API 1631 tank lining on existing 12,000-gallon USTs. The following outlines the scope of work: ▪Prepare health and safety and work plans, procure materials, schedule tasks, and coordinate with the regulators. ▪Mobilization—Mob to site. Purchase equipment, epoxy to be billed at 50 percent of the project total prior to mobilization. If a tank cannot be lined a credit for materials shall be issued. ▪CGRS will de-gas the UST with a forced air venturi dispersing vapors . Once the LEL (lower explosive limit) is down to zero (0) CGRS shall cut into the UST. Each tank is anticipated to take 4-days to complete. CGRS shall inspect the shoring to ensure proper installation in the excavation. ▪CGRS shall vent UST. CGRS shall prepare the tank for confined space entry and clean the tank. CGRS will use a 4-gas air monitor to observe the tanks’ conditions every time a confined space certified employee is going to enter the tank and every 60 minutes as well. CGRS crew members retain certifications in 40 Hazwoper, Confined Space, Ultrasonic Testing, and ICC. A three to four-man crew on-site at all times because we are trained and have the proper equipment to complete a safe retrieval of a crew member if the confined space entrant was to sustain an injury or become unconscious. Any remining petroleum waste shall be drummed for disposal by owner. ▪The tank shall be abrasion blasted and the blast material removed. CGRS’s engineer shall evaluate the tank structurally and ensure the UST is fit for repairs. The tank shall be repaired with boiler plugs and fiberglass. ▪The tank shall be fully epoxy lined with a fuel compatible liner from Enviroline. After the tank has dried for 12 to 18 hours, CGRS shall enter the tank to measure liner thickness and cover any coating holidays. ▪CGRS shall inspect work quality after completion and install bolt on man-way lids for future access. Any work 2 www.cgrs.com 800.288.2657 1301 Academy Ct. Fort Collins, CO 80524 Jackson Energy Cottonwood Heights, UT - UST Lining quality issues shall be corrected prior to calling for inspection by UT DEQ. ▪CGRS shall prepare a report summarizing findings, structural analysis , documenting finished work product and provide a 1-year warranty for the UST’s liner. ▪Coordinate with client for punch list items. 3 www.cgrs.com 800.288.2657 1301 Academy Ct. Fort Collins, CO 80524 Jackson Energy Cottonwood Heights, UT - UST Lining at a minimum of 8” thick. ▪ Exclusion 3: It is assumed no more than 150-gallons of fuel shall be left in each tank for cleanout. Additional fuel shall be billed at $1.85 per gallon over this amount per tank. Drums of fuel shall be labeled and left onsite for the customer to dispose of. ▪ Exclusion 4: Costing include coordination for permitting. The cost of the permit is unknow until the permit is applied for. Permit costs are usually less than $3,000. The cost of the permit shall be billed as a line item outside of the lump sum costs. If additional work is required due to a change in the scope of work or unanticipated site conditions, costs will be presented to the owner prior to implementation. Insurance CGRS will provide all necessary labor, equipment, materials and permits to complete the foregoing work specifications, as well as, commercial general, professional and pollution liability insurance coverage (up to $5,000,000 aggregate). CGRS will also provide standard workers’ compensation and employers’ liability coverage, as well as, system certification, warranty compliance, and system startup.

CHAPTER D REPAIR AND LINING OF FIBERGLASS TANKS INTRODUCTION Chapter D outlines comprehensive repair and lining procedures for fiberglass tanks to meet the requirements of Federal Regulation 40 CFR Part 280.32 and 280.33(b). Chapter D specifies procedures for structural assessment, repair, and lining for compatibility of underground fiberglass tanks. On pages 37139 and 37140 of the preamble of Federal Regulation 40 CFR Part 280 the EPA expressed the following: 1. "The EPA proposed that repairs to FRP tanks be made only by the manufacturer's authorized representatives". 2. "EPA has decided to change the proposed requirement to allow not only the manufacturer's authorized representatives to repair FRP tanks but to also allow qualified in-house personnel to conduct repairs if a code of practice developed by a nationally recognized organization or independent testing organization is followed". 3. "Information presented by commentaries convinced the Agency that there are other qualified and competent individuals who could provide reliable and proper repair services for FRP UST systems". 4. "The agency also believes that allowing repairs to be conducted by other qua lified in-house personnel in accordance with an industry code of practice will help ensure that there are adequate repair personnel available to provide competent repair services in a timely manner". The preamble of 40 CFR 280.33 also stated "Though there are no currently established industry standard codes for repair of FRP tanks, at least one nationally recognized association is presently developing such a code". Therefore, the agency believes it would be imprudent to restrict repair services to only manufacturer's authorized representatives". Accordingly, Chapter D of this standard establishes an industry code of practice for the repair of fiberglass tanks to allow In-house personnel to meet the requirements of 40 CFR 280.33(b). Additionally, chapter D outlines minimum criteria for upgrading FRP tanks for compatibility to meet the requirements of 40 CFR 280.32. CHAPTER D THE REPAIR AND LINING OF FIBERGLASS TANKS D1.0 SCOPE D1.1 Chapter D specifies minimum procedures for the repair of fiberglass tanks in accordance with t he Code of Federal Regulations 40 CFR Part 280.33(b). The Code of Federal Regulation 40 CFR Part 280.33(b) states "Repairs to fiberglass reinforced plastic tanks may be made by the manufacturers authorized representative or in accordance with a code of practice developed by a nationally recognized association or independent testing laboratory". Chapter D is a code of practice for the repair of fiberglass tanks to comply with 40 CFR 280.33(b). Included under the scope of Chapter D are procedures for upgrading existing fiberglass tanks to be compatible with future fuels such as methanal to meet the requirements of 40 CFR 280.32. D1.2 In general, Chapter D specifies procedures for structural assessment, repair, lining for compatibility, and closing the access opening of underground fiberglass tanks. D2.0 DEFINITIONS D2.1 COMPATIBILITY - Deterioration of an FRP laminate which can result from the incompatibility of the product being stored or an improperly cured laminate. D2.2 CRAZING - Hairline cracks either within or on the surface of a laminate, usually caused by impact stresses or excessive flexing. D2.3 CRACK - A split or break in the FRP which can extend through the tank wall. D2.4 DEFLECTION - A geometric distortion of the tank diameter. Diameter measurements determine slump or out-of- round status of the tank. D2.5 DELAMINATION - The rupture of internal bonding between layers of fiberglass and resin. D2.6 DOME - The end section of a cylindrical tank. Domes usually are hemispherical, elliptical, or domed shaped. D2.7 FRP - Fiberglass reinforced plastic thermosetting resin laminate. D2.8 FLAT - The tank wall portion between the rib structures. D2.9 FRACTURE - A crack in the FRP sometimes causing delamination. D2.10 HAND LAY UP - A technique in which fiberglass materials and catalyzed resin are laid over or onto another fiberglass part, by hand. These materials are then compressed with a roller to eliminate entrapped air. D2.11 JOINT - Where two fiberglass laminates overlap and are bonded together and sealed. Joints are usually found where the end caps meet the tank wall. D2.12 LAMINATE - A unit of material composed of several layers of fiberglass and resin. D2.13 LIFT LUG - Lugs fastened to the tank top for use in lifting and positioning the tank. D2.14 PUNCTURE - A hole or penetration in surface of the FRP laminate. D2.15 RIB - A structural component of a tank designed to provide tank stiffness and resistance to external loads. D2.16 SEAM - Where the edges of two fiberglass laminates meet and are sealed and bonded together. Seams are usually found on the tank walls. D2.17 SPLASH - A portion of FRP which is formed on the tank on an identical area to the one that was damaged. It is used to replace damaged or missing sections. D2.18 STRIKERPLATE - A steel plate laminated on the inside tank bottom under fittings for protection from potential dip stick puncture or other mechanical abuse. D2.19 WAX COAT - A wax bearing resin usually applied to the inside of FRP tanks to enhance chemical resistance. D2.20 WET OUT - The ability of a resin to saturate the glass reinforcement. D3.0 APPROVALS D3.1 The local authorities shall be consulted prior to beginning any on-site work to obtain necessary permits. D4.0 TRAINING AND CERTIFICATIONS D4.1 The contractor shall sign form DF1 certifying to the tank owner that the employee(s) performing the tank repairs or lining are knowledgeable in confined space entry procedures, and of the purging, entry, and cleaning procedures contained in sections A5.0 through A 9.0 of Chapter A. D4.2 The contractor and special inspector shall sign affidavit form DF2 certifying to the tank owner that all work was performed in accordance with chapter D of this standard. The tank owner shall acknowledge receipt of form DF2 by signing form DF2. D5.0 SAFETY PRECAUTIONS D5.1 STATIC ELECTRICITY PRECAUTIONS D5.1.1 Electrically isolated tanks such as fiberglass reinforced plastic tanks will not allow the dissipation of static electricity and shall not be used as a grounding source for equipment. D5.1.2 Personnel entering an FRP tank during the initial cleaning operation (Section A8.0 of Chapter A) shall wear shoes, gloves, and clothing that will allow discharges of static electric charges. To prevent build up of static electric charges, a bonding cable shall be attached to the entry personnel's clothing. The bonding cable shall be attached to an adequate grounding source that is located outside the tank. All articles of clothing shall be interconnected to provide discharge of potential static electric charges through the grounding cable. D5.2 The procedures outlined in section A5.0 of Chapter A shall be performed prior to proceeding to the tank opening procedures contained in section D5.3. D5.3 OPENING THE TANK NOTE: An abrasion or grinding wheel must not be used on a tank until the tank has been cleaned in accordance with section D5.4 of this Chapter. D5.3.1 Vapor readings shall be taken immediately prior to removing the manway cover or cutting the access opening as described in Chapter A, section A5.2.4 of this standard. If vapor readings indicate the vapor concentration is at 10 percent or less of the lower flammable limit (LFL), the manway cover may be removed or a hole maybe drilled as described in section D5.3.3. Vapor readings shall be performed throughout the opening process to ensure a safe atmosphere is maintained. D5.3.2 Ventilation should be maintained throughout the opening process. When an air blower system is used, minimal air pressure should be applied as necessary to maintain a safe atmosphere to prevent the sudden release of air pressure from the tank or blowout of the tank plate or manway lid during opening. D5.3.3 If no manway cover exists, a access opening shall be cold cut in the dome of the tank with the minimum dimensions of 22 inches by 22 inches. All perimeters of the dome section to be cut shall be at least 8 inches from the tank's ribs. One hole shall be drilled with an air driven drill at the corner of the section to be removed using lubricating oil to reduce friction, heat, and possible sparks. D5.3.4 After removing the manway cover or drilling the hole, vapors must aga in be tested. Vapor testing shall be performed by inserting the probe into the manway or drilled hole. An access opening shall not be cut until vapor readings do not exceed 10 percent of lower flammable limit (LFL). D5.3.5 The access opening shall be bevel cut using an air driven saber saw. Lubricating oil should be used during the opening process to reduce friction, heat, and possible sparks. D5.4 PRE-ENTRY & TANK CLEANING PROCEDURES D5.4.1 The pre-entry and cleaning procedures described in sections A7.0 through A8.6 of Chapter A shall be performed prior to proceeding to section D6.0 of this chapter. D6.0 TANK INSPECTION D6.1 Ventilation shall be maintained throughout the inspection procedures. D6.2 Immediately prior to entering the tank, vapor readings shall be taken to ensure that a safe atmosphere exists. Vapor readings shall also be taken periodically throughout the inspection procedures. D6.3 During tank inspection, only a Class 1, Division 1, Group D explosion proof light shall be used. D6.4 VISUAL INSPECTION D6.4.1 The interior of the tank shall be visually inspected for signs of local buckling, surface cracking, fractures, punctures, delamination, chemical attack, or other damage. Graphite powder should be rubbed vigorously on the interior tank wall surface to seek out cracks, stressed areas and holes which may not be visually noticeable. D6.4.2 Vertical and horizontal measurements shall be taken longitudinally every three feet of the interior diameter to determine if geometric distortion has occurred. Note: Geometric distortion repairs are not included under the scope of this chapter. Geome tric distortion usually occurs as a result of improper installation practices. If measurements indicate that the tank has compressed more than 1% of the original diameter, a professional engineer or the tank manufacturer should be consulted to determine if the tank is suitable for repair. D6.4.3 The tank shell wall shall be hardness tested using a Barcol Hardness tester, GYZJ 935, or other acceptable instrument to determine if the tank shell wall hardness meets the manufacturer's specifications to determine whether chemical attack has occurred. Barcol hardness measurements shall be recorded on form D2. If the tank shell wall does not meet the manufacture's minimum barcol hardness specifications, the tank shall be lined in accordance with section D8.0 or closed. Note: If a fiberglass tank has been determined to be leaking and no visual evidence of damage is evident upon visual inspection of the interior and the tank fittings have been determined to be tight, the tank may be leaking from the seams or joints. If the seams or joints are determined to be leaking, the tank should be repaired in accordance with section D7.2.1. D7.0 TANK REPAIR PROCEDURES D7.1 REPAIR AND LINING MATERIAL CRITERIA D7.1.1 The repair and lining material shall meet the requirements of section A4.4 of chapter A of this standard. D7.2 REPAIRS D7.2.1 Fractures, punctures, surface cracking, seams, joints, and missing sections shall be repaired as follows: D7.2.1.1 All loose and delaminated glass shall be removed from the repair area. D7.2.1.2 If a section of the tank is missing, a splash shall be cut one half inch-larger on all sides than the section that is missing. The edges and the side of the splash that the repair FRP laminates will be applied shall be sandblasted or ground in accordance with D7.2.1.3 of this Chapter. The splash shall be attached over the missing section with lining material. D7.2.1.3 Surface preparation shall be performed by sandb lasting or grinding the damaged area. An area extending at least 12 inches beyond the perimeter of the repair area shall be sandblasted or ground. If a seam or joint is in need of repair, the repair area shall extend the entire length of the seam or joint. The sandblasted or ground surface shall be clean of all foreign matter and have a rough appearance with glass fiber exposed. Abrasive blast operations shall be performed in accordance with section A9.0 of Chapter A. NOTE: SANDBLASTING IS PREFERRED BECAUSE IT WILL EXPOSE GLASS FIBERS DURING SURFACE PREPARATION TO PROVIDE A MECHANICAL BOND FOR THE REPAIR OR LINING MATERIAL. GRINDING MAY SHEAR OR MELT GLASS FIBERS AND NOT EXPOSE AS MANY GLASS FIBERS TO PROVIDE AS STRONG A BONDING SURFACE. D7.2.1.4 Fractures shall have holes drilled at each end of the fracture. The drilled holes shall be larger in diameter than the width of the fracture. D7.2.1.5 Once surface preparation is complete, multiple layers of 1.5 oz/sq-ft fiberglass mat shall be applied to the damaged area. The initial layer of fiberglass mat shall extend at least 4 inches beyond the perimeter of the damaged area. Additional layers sha ll extend an additional 2 inches beyond the perimeter of the previous applied layer of fiberglass matting that was applied. If a splash was incorporated to repair the damaged area, the fiberglass mat shall be applied over the splash and overlap to the tank walls as described above. The finish laminate shall be of equal or greater thickness than the original tank wall. D7.2.2 TANK FITTING REPAIRS Repairs to tank fittings shall be conducted as follows: D7.2.2.1 The fitting plate assembly shall be removed by grinding or cutting along the perimeter of the edges of the steel plate. D7.2.2.2 If the area that the fitting plate was attached is damaged, the damage shall be repaired in accordance with section D7.2.1 of this Chapter. D7.2.2.3 If necessary, a hole shall be cut into the tank for the new tank fitting. D7.2.2.4 The entire surface of both sides of the tank fitting assembly shall be sandblasted to white metal. D7.2.2.5 The fitting plate assembly shall be attached to the tank with lining material. The lining material shall be applied to the top of the tank and the bottom of the fitting plate assembly flange. The fitting plate assembly shall then be secured to the top of the tank with clamps or self tapping bolts. If self tapping bolts are used, the top of the bolts shall be sealed with lining material. D7.2.2.6 An initial layer of 1.5oz -Sq/ft chopped mat shall be applied over the fitting plate assembly cover and any adjoining areas of the tank. Alternating layers of 24 oz-sq/ft and 1.5 oz-sq/ft chopped mat shall then be applied over the initial layer of 1.5 oz-sq/ft chopped mat. The final layer of glass mat shall be 1.5 oz-sq/ft chopped mat. D7.2.2.7 The fitting plate assembly shall be tested in accordance with section D12.0 of this chapter. D7.2.3 MANWAY REPAIR OR INSTALLATION PROCEDURE If the joint between the manway assembly and tank is leaking, the manway assembly is damaged, or a new manway assembly is being added, the repair shall be conducted as follows: D7.2.3.1 The manway assembly shall be removed by cutting around the manway neck on the top of the tank. The cut should be made so that the hole is only slightly larger than the manway assembly that will be installed. D7.2.3.2 If the manway assembly was damaged, a new manway assembly shall be installed. D7.2.3.3 Both sides of the manway assembly and tank wall shall be sandblasted or ground where glass and resin are to be applied to remove all foreign matter and to achieve a rough surface. D7.2.3.4 The manway assembly shall be placed and secured in the hole that was cut into the tank. The manway assembly shall be centered in the hole and level in all directions. D7.2.3.5 Once the manway assembly has been leveled and centered, lining material shall be applied to both the exterior and interior of the joint between the tank hole and manway assembly. D7.2.3.6 After the lining material has cured, an initial layer of 1.5 oz-sq/ft fiberglass chopped mat shall be applied to the outside of the manway neck and the top of the tank. Alternating layers of 24 oz - sq/ft woven roving and 1.5 oz - sq/ft chopped mat shall be applied over the initial layer. If possible, additional layers of fiberglass matting shall overlap the perimeters of each previous layer by at least one inch. The final layer of the fibergla ss laminate shall be 1.5 oz -sq/ft chopped mat and extend at least 3 inches onto the tank and manway neck. D7.2.3.7 The inside of the manway shall have fiberglass matting applied as described in section D7.2.4.6. The laminate shall extend from the inside of manway neck onto the interior tank wall and shall have a final gelcoat finish. D7.2.3.8 The manway assembly shall be tested in accordance with section D12.0 of this chapter. D8.0 LINING FOR COMPATIBILITY Tanks may be upgraded as follows to provide compatibility with products other than those that were intended to be stored when the tank was originally manufactured: D8.1 The entire interior surface of the tank shall be ground or abrasive blasted to achieve a rough surface free of all fo reign matter. If selected, abrasive blasting operations shall be conducted in accordance with section A9.0 of chapter A. D8.2 The lining material shall meet the performance requirements of section A4.4 of Chapter A for the product intended to be stored. D8.3 The lining shall be applied in accordance section A11.2.5 of Chapter A and shall be at least 100 to 125 mils thick. D8.4 If a heater is used to accelerate the curing process, all other work that might release flammable vapors in the work area shall be halted. The heating unit shall be attended whenever it is in operation. The temperature within the tank shall not exceed 125 degrees fahrenheit. D8.5 The lining shall be tested in accordance with section D10.0 of this chapter. D9.0 STRIKER PLATE INSTALLATION D9.1 A 1/4" steel striker plate with the minimum dimensions of 8" x 8" shall be installed under the gauge and fill openings if the tank was interior lined in accordance with 8.0 or 7.2.2 or if steel striker plates were not found to be installed when internally inspected. D10.0 TESTING D10.1 If the tank was lined in accordance with section 8.0 or 7.2.2 of this chapter, the lining shall be hardness tested using a Barcol Hardness Tester, GYZJ 935, or other acceptable instrument to determine if the hardness meets the lining material manufacturer's specifications. The lining shall meet the lining material manufacturer's hardness specifications prior to proceeding to section 11.0. D10.2 If the tank was lined in accordance with section 8.0, the lining thickness shall be determined using a wet film gauge during the lining application. D11.0 TANK CLOSING D11.1 If an opening was cut, the removed section of the end cap and a minimum six inches of the adjoining tank wall surface shall be abrasive blasted. D11.2 The cut edges of the end cap and the section that was removed shall be sealed with lining material prior to replacing the section. D11.3 The access opening shall be closed by replacing the end cap section that was previously removed. D11.4 The seams of the entry hole shall be sealed by the application of five plies of 1-1/2 oz/sq-ft fiberglass chopped strand matting saturated with lining material which extends a minimum of 4 inches beyond the perimeter of the access opening seams. All fiberglass material shall be treated with silane. The final laminate shall be equal to or exceed the wall thickness of the tank. D12.0 FINAL TESTING A12.1 The access opening seal and accessible areas that were repaired shall be tested by performing an air -pressure soap test of the cover plate and seal area. The tank and/or attached lines shall be pneumatically tested using five pounds per square inch gauge (5 PSIG) air pressure. A soap solution shall be applied to the access opening seal and accessible repair areas and shall be inspected for bubbles. Air pressure testing shall be performed while the tank is free of petroleum product, liquid, or vapors and prior to covering the cover plate with backfill.
