AMENDED SILICATES INJECTION SYSTEM

1. General Description

This specification covers the overall description, work scope, technical and performance requirements of a reagent injection system for a mercury emission control project. The specification requirements listed herein are based primarily on the work by Jenike & Johanson for Novinda and represent the minimum requirements to achieve consistent flow of the amended silicates material, and Novinda retains the right to review Owners design and drawings prior to fabrication and installation of the injection system. Designs deviating from these specifications may be considered on a case by case basis.

2. Scope of Work

The scope of work is to design, engineer, procure, fabricate and deliver the specified reagent injection system, support start up and testing of a complete, fully functional and operational mercury emission control system, which includes at a minimum but not limited to the items and services listed below. A typical schematic flow diagram of the injection system with termination points for the scope of work is shown in Appendix A.

1. Reagent Injection System including transfer blowers, material metering and feeding equipment and all required manual and motorized valves.

2. Reagent storage silo with vacuum/pressure relief door, bin vent fabric filter & vent fan and transfer pipe suitable to receive and transfer material from either rail cars or delivery trucks.

3. Transfer pipes from blower discharge to lance inlets including manual isolation valve at each. 4. All auxiliary electric system and controls for above scope.

3. Material Properties

The injection system shall be capable of unloading, handling, feeding, and injecting multiple sorbent materials, including amended silicates and powdered activated carbon (PAC). Detailed material properties and injection equipment design criteria for amended silicates are provided by Jenike & Johanson (J&J) and are listed within this specification section. Equipment design and operational considerations for the explosive and flammable properties of any sorbent material is the responsibility of the Owner and Bidder. Bidder shall also be responsible for ensuring that other PAC materials can be also utilized by the injection system. The injection system silo shall be designed to allow mass flow instead of funnel flow. A mass flow silo allows for first-in-first-out material flow, eliminates ratholes and stagnant material, and minimizes material segregation effects. The following criterion represents typical limiting conditions for flow, therefore larger silo outlets, steeper hoppers, and flow rates summarized below are acceptable: Cohesive Strength Since sorbent materials are cohesive and have the capacity to form a rathole in the injection system storage silo, the following are minimum mass flow silo discharge outlet diameter dimensions for gravity feed (GF) and air assisted silo bin bottoms. Continuous flow (GF) 1.3 feet After 1 day at rest (GF) 2.1 feet

Rev. 10/09/13 Page 3 of 9

For air assisted silo bin bottom 0.5 feet Compressibility Bulk density shall be considered in the design for silo loads, silo capacities, and system feed density. The range of bulk density for the amended silicates material is as follows: Measured range of bulk density 32.2 to 58.5 pounds per cubic foot PAC assumed bulk density 30 pounds per cubic foot Mass Flow Hopper Angles Design of the mass flow silo hopper shall include hopper angle, materials of construction, and surface finish. Hopper material shall have interior sloping surfaces lined with 304 stainless steel and #2B finish (cold rolled mill finish which cannot be achieved by polishing). Maximum recommended mass flow wall angles 10 degrees (from vertical for both continuous flow and after 1 day storage at rest) The MSDS for the amended silicates material can be found in Appendix B.

4.2.2 Equipment Details

4.2.2.1 Reagent Storage Silo

The storage silo shall be designed to operate in Mass Flow when charged with Amended Silicates reagent, which exhibits material properties as described in Section 3 above. The storage silo shall be of welded construction with a roof for weather protection. It shall have an active storage capacity of 14-days calculated at maximum required reagent feed rate. It shall be provided with a fill pipe for pneumatic transfer of material from rail cars or delivery trucks using rail/truck transfer blowers. The silo shall have appropriately sized bin vent fabric filter with vent fan, a vacuum/pressure relief door at the roof, a caged ladder, roof man-way, safety railings, roof mounted level indicators and a side-wall mounted refill level indicator. Poke holes and access doors are not recommended for a mass flow silo since they have a tendency to restrict material flow; however, if necessary they shall be located in the vertical cylindrical section instead of the hopper. The material of construction for the cylindrical section shall be carbon steel and the conical section at the hopper bottom shall be constructed or have interior surface lined with 304 stainless steel, with #2B finish. Sheet thickness 10 gauge or thinner generally result in a smoother finish, which facilitates better material flow. As noted earlier, the conical section shall be designed to facilitate Mass Flow of material and avoid plugging. The hopper shall be designed to incorporate the use of an air-assisted discharge system, which consists of a 304 #2B lined conical hopper and the air-assisted discharger; with the hopper and air-assisted discharger being connected by a short vertical section required to maintain uniform flow (See Section 6.0). The material in the hopper is not intended to fluidize until material level drops below 5 feet.

4.2.2.2 Air-assisted Discharger

The air-assisted discharge membrane shall have a minimum pressure drop of 0.035 psi per scfm per sq. ft. of membrane area. The air supply should provide a no-flow pressure of 1.1 psig, maintain a pressure of 0.5 psig at 148.5 scfm, and provide a maximum (choked) flow of 6.4 scfm/ft2 of projected horizontal discharger area. Expected air flow during discharge is approximately 3.6 to 5.7 scfm/ft2 of projected horizontal discharger area. The recommended material for

Rev. 10/09/13 Page 5 of 9

the membrane is Polyveyor 1950 which is available from BeltService Corporation, or J&J approved equal.

The air-assisted discharger shall be a standard 6 foot diameter unit with minimum 6 inch outlet, and be supplied by Premier Pneumatics, Kice Industries, Nol-Tec Systems, Young Industries, Clyde Bergemann, or J&J approved equal.

Acute effects Dust in the eyes will cause irritation. May cause skin irritation.Local effects Inhalation of dusts may cause respiratory irritation.Chronic effects In 1997, IARC (the International Agency for Research on Cancer) concluded that crystalline silica

inhaled from occupational sources can cause lung cancer in humans. However in making theoverall evaluation, IARC noted that "carcinogenicity was not detected in all industrialcircumstances studied. Carcinogenicity may be dependent on inherent characteristics of thecrystalline silica or on external factors affecting its biological activity or distribution of itspolymorphs." (IARC Monographs on the evaluation of the carcinogenic risks of chemicals tohumans, Silica, silicates dust and organic fibres, 1997, Vol. 68, IARC, Lyon, France.)

In June 2003, SCOEL (the EU Scientific Committee on Occupational Exposure Limits) concludedthat the main effect in humans of the inhalation of respirable crystalline silica dust is silicosis."There is sufficient information to conclude that the relative risk of lung cancer is increased inpersons with silicosis (and, apparently, not in employees without silicosis exposed to silica dust inquarries and in the ceramic industry). Therefore, preventing the onset of silicosis will also reducethe cancer risk..." (SCOEL SUM Doc 94-final, June 2003)

According to the current state of the art, worker protection against silicosis can be consistentlyassured by respecting the existing regulatory occupational exposure limits. Occupationalexposure to nuisance dust (total and respirable) and respirable crystalline silica should bemonitored and controlled.
