Examples include ORC socks, iSOC systems, and other gas infusion methods. 2) Small-Scale In jection O perations -Injection wells located within a land surface area not to exceed 10,000 square feet for the purpose of soil or groundwater remediation or tracer tests. An individual permit shall be required for test or treatment areas exceeding 10,000 square feet. 3) Pilot Tests -Preliminary studies conducted for the purpose of evaluating the technical feasibility of a remediation strategy in order to develop a full scale remediation plan for future implementation, and where the surface area of the injection zone wells are located within an area that does not exceed five percent of the land surface above the known extent of groundwater contamination. An individual permit shall be required to conduct more than one pilot test on any separate groundwater contaminant plume. 4) Air In jection Wells -Used to inject ambient air to enhance in-situ treatment of soil or groundwater.

SUMMARY EnviroClean is a non-flammable, non-toxic, water-based, proprietary blend of non-ionic ethoxylated octylphenolic surfactants that has been specifically engineered as a cleanup/mitigation agent for a wide range of hydrocarbon products. EnviroClean has been shown to be effective for quickly and effectively suppressing or completely eliminating voes, LEL's, benzene and low levels of H2S and mercaptans in open or confined spaces. EnviroClean has been used for cleanup of hydrocarbon spills and soil remediation. In these applications , EnviroClean effectively conditions (physically) the hydrocarbon such that the microbes that naturally· occur can more readily consume it. It turns hydrocarbons into a nutrient source for the microbes . When sufficiently mixed with hydrocarbon and water, the EnviroClean forms a homogeneous solution of hydrocarbon, EnviroClean and water, whi _ch is very stable. EnviroClean is a concentrated product that readily biodegrades. EnviroClean is commercially available in ~allon units , 5~allon drums , 275 and 330-gallon totes and bulk from Oklahoma City, Oklahoma and Houston, Texas . Page 1 of 2 FLUID DESIGN EnviroClean is a proprietary blend of surfactants that needs to be diluted to be effective and it is very safe to workers and the environment. EnviroClean does not contain caustic, therefore does not have the common harmful side effects associated with caustic based products. The product is designed for use as a degassing agent and a cleaner/degreaser for remediation. The product does not contain any enzymes or biomass itself. It works by conditioning the hydrocarbon so that the naturally occurring microbes (bacteria) are able to readily consume it. Through the application of the appropriate dilution and mixing, the EnviroClean will capture the hydrocarbon and tie it up in a solution that is very stable. The formation of this solution results in extremely small particles that will not recoalesce. It is important to note that if EnviroClean reaches its saturation point the oversaturated hydrocarbon will breakout of solution very quickly. This will allow for easy removal or reclamation of any hydrocarbon that is not preconditioned for remediation. In addition to tying up the hydrocarbon in solution, the product is very effective when contacted with hydrocarbon vapors at suppressing volatile organic vapors, gases, and odors. Once combustible and flammable hydrocarbon vapors are tied up in the resultant solution, the solution will be very difficult to ignite . It also accelerates the biodegradation process of the hydrocarbon, thereby enhancing recycling or reclamation of water. EnviroClean has been demonstrated to be effective on gas, oil, lube oil, hydraulic oil, most petroleum-based products, animal and vegetable oils, fats, and tallow oils. EnviroClean cleans the heavy tar build-up, asphaltenes or oily residue from inside of tanks and vessels . Furthermore , once a surface has been cleaned with EnviroClean , the cleaned surface will resist the deposition of oily materials . EnviroClean can be used to cleanup oil spills whether in/on soil or hard surfaces. The first step in this process is to remove as much of the free oil as possible. This step is followed by contacting the contaminated surface appropriately with the proper dilution of EnviroClean and water. The treatment solution will contact the hydrocarbon molecules and change their behavior such that they are now essentially water soluble . The large increase in interfacial surface area creates conditions that are favorable to degradation and consumption by bacteria and microbes. The product converts hydrocarbons into a very good nutrient source for bacteria and microbes. EnviroClean is typically fed at concentrations between 1 % and 6%, depending on the nature of the hydrocarbon contamination problem. It can be diluted with most types of water -hard, soft or brackish water. The product has an unlimited shelf life when unopened. EnviroClean is effective at ambient temperatures. However, the effectiveness will increase as the tem perature of the a lication is increased. EnviroClean does not require the use of steam, but has been shown to be very effective when injected into the steam (vapor) phase. FIELD MIXING PROCEDURES Mixing Concentrates EnviroClean is usually delivered as a concentrate and must be diluted with water to work properly. Cleaning solutions can be formulated by premixing or eduction. It is not necessary to provide high shear agitation when preparing a batch of cleaning solution since EnviroClean is 100% soluble in water. It is recommended that when preparing the cleaning solution you first add the water into the mix container and then follow by the addition of EnviroClean. This will minimize foaming as the EnviroClean and water form a homogeneous solution. For premixing, the following procedure may be used: 1. Add the correct amount of water to the container. 2. Depending on the desired strength, add the correct amount of EnviroClean to the container. 3. If the final solution is not a consistent pink color, mild agitation may be required until a consistent pink color is achieved. Quality Control Testing There is no easy field testing procedure to monitor the concentration of active ingredients in the EnviroClean formulation. Visually the color changes from rose color to lighter pink as the product is further diluted. Effectiveness can also be predicted by quantifying the amount of hydrocarbon that is to be picked up. By observing the effluent from the use of EnviroClean, an adjustment in the cleaning solution concentration can be made. If it is observed that free oil is floating on the effluent Page 2 of 2 solution, then the concentration should be increased.
