FEDERAL HAZARDOUS WASTE

Federally, Hazardous Waste Test Method SW-846 Test Method 1311: Toxicity Characteristic Leaching Procedure (TCLP), is used to determine the mobility of both organic and inorganic analytes present in liquid, solid and multiphasic wastes. This method is a SW-846 Method-Defined Parameter (MDP), meaning that it may not be modified when used for Resource Conservation and Recovery Act (RCRA) testing. RCRA specifically identifies 8 heavy metals with legally enforceable limits. If any of the metals exceed the US EPA allowable limits, they may not be disposed of in a standard landfill and are subject to hazardous waste handling protocol. Green Diamond Abrasives do not exceed any of the EPA allowable limits identified by RCRA.

In addition to the RCRA limits for hazardous waste, there are federal limits for other metals described in 40CFR part 268 for Land Disposal Restrictions (LDR) and are also regulated using the TCLP. Green Diamond Abrasives do not exceed any of the LDR Limits.

CALIFORNIA TITLE 22

While the TCLP is the federal test used to determine hazardous waste under the RCRA guidelines, the State of California utilizes Soluble Threshold Limit Concentration (STLC) and Total Threshold Limit Concentration (TTLC) to determine hazardous waste under Title 22. In the State of California, the regulations set forth in Title 22 override the federal regulations outlined by RCRA. The intent of the STLC is to simulate conditions that may be present in a landfill where water may pass and travel into groundwater, and the TTLC determines the total concentration of each analyte. Green Diamond Abrasives do not exceed any of the California Title 22 Limits.

The Occupational Safety and Health Administration (OSHA) sets legal limits in the United States for exposure of an employee to a chemical substance or physical agent know as a Permissible Exposure Limit (PEL) and also sets Action Levels for specific substances. The PELs and Action Levels are based on an 8-hour time-weighted average (TWA). An employee's average airborne exposure in any 8-hour work shift shall not exceeded these limits. If an 8-hour TWA reaches the action level or PEL, certain provisions of the OSHA standard must be initiated (e.g., medical surveillance, air monitoring, biological monitoring). Industrial hygiene monitoring during blast cleaning shows that Green Diamond does not exceed any of the PELs or Action Levels.

The Green Diamond particle is an amorphous glass, and as such, contains no crystalline

structure or form. The metallic constituents that make up the Green Diamond particle are in a phase analogous to common window glass or a beer bottle. The particle is formed in an oxidizing environment and the constituent elements are reported as oxides as a matter of chemical convention as seen on documents such as the SDS. For example, a lab may report X% SiO2 but the silicon is in a non-crystalline vitreous state (glass), meaning there is no available respirable crystalline silica in the system. This is why the Green Diamond particle is safe to use and is reported below the level of detection during air monitoring tests.

Therefore, the Green Diamond particle contains no free respirable silica, does not

exceed limits set forth by OSHA’s PELs or Action Levels, and does not exceed any Federal or State limit for hazardous waste.

Total Cost: Cleaning rate, material cost and an optimized flow rate, dictate the TOTAL Cost of Blast Abrasive cleaning and surface preparation. Superior cleaning rates and low material costs make Green Diamond Abrasives the most cost effective in the industry.

A Declining Resource: The American Coal Ash Association (ACAA) estimates that less than 2 million tons of coal slag are created each year, and as the use of coal continues to decrease in power generation, that number will continue to decline.

Green Diamond vs. Coal Slag

Cost and Efficiency of Green Diamond Abrasives vs. Coal Slag

Independent testing revels that Coal Slag has a higher total cost and lower cleaning rate compared to Green Diamond Performance Materials’ abrasives when blasting to an SP-5 white metal surface on SSPC Grade B new steel at 100 psi, measured at the nozzle, and optimized flow-rate for each abrasive’s bulk density. These results are reported as percentages relative to the measured performance of Green Diamond Abrasives. Delivered costs of material will vary based on packaging, location and quantity.

• Consistency from single source in the USA• Cleanliness and low dusting• Outstanding customer service

Green Diamond

Coal Slag


Density Disparity: Because Green Diamond is 25% less dense than copper slag, yet optimizes at nearly the same flow rate, you get 25% more abrasive per truck load which means you get 25% blasting done.

Source: In today’s market, many companies are forced to blend, cut and dilute their abrasives to remain competitive. Copper slag is often comprised of materials from various sources of variable quality resulting heterogeneous products.

While Crushed Glass is both abundant and low cost on a pound to pound basis, it is inferior in cleaning rate (sq.ft./hr.) and ability to profile, which in turn, leads to an overall higher cost of blasting when compared to Green Diamond Abrasives.

Worksite Conditions: Because of the low MOHS hardness of crushed glass, and internal micro-fractures generated during the recycling process, worksite conditions become dusty, quickly. The lack of productivity with crushed glass means blasters spend nearly 2X the amount of time blasting per sq. ft., which means more spent abrasive accumulates in the air and on the ground, further increasing the cost of cleanup and disposal.

Total Cost Savings GDPM 11% 12%

Price does not equal performance: It is no secret that Garnet is a top performing blast media, but in terms of total cost, it trails behind Green Diamond. Recent tests show that Green Diamond Abrasives and Garnet are near equal performers but Green Diamond comes at a much lower price. Total cost savings are easily realized without sacrificing cleaning rates or depth of profile.

Availability: According to the USGS, only 3.1% of all Garnet is mined domestically, making it suseptable to supply interuptions. As was experienced in 2016 and 2017, geopolitical instability resulted in major supply disruptions to the US, and as a result, prices skyrocketed. Green Diamond Abrasives will always be readily available and price stable because they are single sourced in Riddle, Oregon from our exclusive 10-million-ton mineral reserve, equal to +40 years of production.
