3.0 GENERAL PERFORMANCE REQUIREMENTS FOR ABRASIVE MATERIALS

3.1 Qualified Abrasive Product List. The abrasive materials furnished to KMT under this specification shall be products which were approved by KMT Central Engineering for listing, or be eligible to remain so listed, on the applicable Qualified Abrasive Products List at the time set for a bid review of protective coating, lining or surface cleaning project.

3.2 Bulk Abrasive Properties. The abrasive material furnished to KMT shall be manufactured to be compliant with all applicable requirements of this specification and be of uniform size, homogeneous, noncaking, and free flowing.

3.2.1Material Origin. Unless otherwise specified, all abrasive materials covered in this specification shall be new (unused) virgin raw materials except, slag by-product abrasive type which is manufactured from solid waste.

3.2.2Moisture Content. The abrasive material shall be supplied dry and its moisture content shall be less than 0.5 wt. % when supplied in sacks or, if so specified, in bulk. There is no moisture limitation for bulk material to be used for wet blasting. Correction of gross weight of abrasive shipment for moisture content is required.

3.2.3Particle Size and Sieve Analysis. Particle size distribution and sieve analysis of abrasive material shall be consistent with attaining the specified surface profile depth, i.e., 1.5 - 2.5 mils range for the exterior coating system applications, and 3.0 - 4.0 mils range for interior lining applications. The abrasive material shall be of such a quality as to allow the specified surface profile depth and sharp jagged contour be all achieved at best economic cost, including production rates. The prepared surface appearance after cleaning shall be, as a minimum, in accordance with the specified SSPC SP standard and exhibit a high degree of chemical cleanliness, the abrasive grit itself shall generate the lowest possible density of abrasive associated dust (Ringelmann Scale opacity) as required by CARB, i.e., not produce visible emissions of more than 20 Kinder Morgan Terminals STANDARD NO.: CS 09900 Appendix A Rev: Original ISSUE DATE:

percent opacity (Ringelmann 1) when performing dry, unconfined blasting in accordance with the specified SP method. After the blasting, the abrasive shall not contain more than 1.8 wt. % of material of 5 microns or smaller particle size.

Designation of size categories of abrasives are based on US Sieve analysis classification, top and bottom screens, prior to blasting with a minimum of 95 percent material being retained between the specific sieves. For example, 12/30 grade designation indicates that about 5 - 10 percent of the material will be retained on a 12 mesh sieve and 90 - 95 percent will be retained on a 30 mesh sieve. Example of typical grade designations and corresponding mesh sizes for abrasives follows:

Grade Mesh Size

Very Course 12/20

Coarse 12/40, 16/30, 16/40

Medium Coarse 16/50, 20/40

Medium Fine 20/50

Fine 30/70

Very Fine 30/100, 40/140 & finer

than the respective limits required by the State of California Department of Health Services. The indicated user's requirements for toxic components were adopted from the MIL-2A-22262B(SH) Military Specification as approved by the U.S. Department of the Navy.

Note 2. The values listed in Table 3 are instantaneous values and not time weighted exposure averages and are, thereby, different than "airborne ceiling values" or Personal Exposure Limits (PEL).

5.3 Maximum Concentration of Contaminants for the Toxicity Characteristic. The manufacturer of the abrasive material shall certify that the maximum concentration of contaminants for toxicity characteristic shall not exceed the values listed in Table 4.

5.4 Toxicological Assessment of Abrasive. The manufacturer of the abrasive blasting product shall provide Certification that the as-supplied abrasive media does not contain the following metals, or known or suspected carcinogenic compounds of these metals [as listed by OSHA, and/or National Toxicology Program (NTP)], in concentrations exceeding 0.1 percent by weight: lead, arsenic, beryllium, cobalt, cadmium, chromium, and nickel. The manufacturer shall also certify that the as-supplied ready for use product does not have any OSHA, IARC and/or NTP listed known or suspected carcinogens intentionally added to the abrasive mix. When known or suspected carcinogens are or may be present, as result of being a trace/impurity in another ingredient(s), the concentration of the agent in the final product must be less than 0.005 wt.% of the abrasive media, unless it is specifically stated in the document that the agent be required to be at lower level.

5.5 Radioactivity. The maximum gross gamma radioactivity of the abrasive material shall not exceed 20.0 picoCuries/gram (determined as if the net gamma photon were produced by Cobalt-60).

5.6 Cobalt-60. The specific concentration of Cobalt-60 shall be below 0.05 picoCurie/gram activity. Kinder Morgan Terminals STANDARD NO.: CS 09900 Appendix A Rev: Original ISSUE DATE:

5.8 Material Identity and Warning Labels. The abrasive material packaging shall be labeled, tagged, or marked with the identity of the material and appropriate hazard warnings. The identity is to be a term which appears on the label, the MSDS, and the list of chemicals, and thus links these three sources of information. The manufacturer's trade name or designation which identifies the finished product is regarded as a permanent and unique identification of the specific abrasive material, but is not sufficient for identification of its chemical components.

5.9 Special Marking. Abrasive material shipped in commercial sacks and bulk shall include the following marking:

This container contains abrasive material that is inorganic or mineral composition which can be used in dry, enclosed blast or unconfined blast cleaning operations where dust limiting air pollution regulations apply.

6.0 QUALITY ASSURANCE INSPECTIONS AND COMPLIANCE

6.1 Quality Assurance Inspections. Unless otherwise specified in the KMT Contract or Purchase Order, the contractor shall be responsible for inspection, including any examinations and tests, of one lot of abrasive material to verify its quality performance requirements. The contractor may use his own or other accredited testing facilities, if all are acceptable to KMT, for performance of inspections for product quality compliance, unless this authority is denied to the contractor by KMT. KMT reserves the right to approve the choice of testing facilities and, if deemed necessary, to perform the Kinder Morgan Terminals STANDARD NO.: CS 09900 Appendix A Rev: Original ISSUE DATE:

APPROVED BY:

inspections set forth in this specification to ensure the services and supplies conform to prescribed requirements.

6.2 Responsibility for Compliance. The performance and inspection requirements set forth in this specification should be a part of the contractor's routine inspection and quality assurance program. The absence of any specific requirements in this specification shall not relieve the contractor of the responsibility for ensuring that all products, supplies and services submitted by the contractor to KMT comply with the overall performance requirements of the contract. Sampling inspection, as a part of surface preparation and coating application operations, is considered an acceptable practice to ascertain conformance to specification requirements, however, this consideration is not an authorization for submission of known defective material, either indicated or actual, nor does it commit KMT to accept defective material or work. All corrective actions necessary to remedy the defective materials and work, including removal of these items from the KMT facility and their proper disposal, are to be performed by contractor at no cost to KMT.

7.0 QUALIFIED ABRASIVE BLASTING PRODUCTS LIST.

The following LIST OF QUALIFIED ABRASIVE BLASTING PRODUCTS has been prepared to aid KMT personnel in selection and acquisition of abrasive materials for protective coating and lining applications covered in respective KMT Engineering Specifications and Standards. All abrasive material products have been assessed, using the manufacturer's technical data sheets, MSDS, and other referenced sources of information, for their compliance with KMT's criteria of technical performance, and health and environmental requirements covered in this specification. This list is to be periodically revised, updated, changed or amended by KMT Central Engineering, and will be reissued as required, without notice to vendors. The listing of an abrasive material in this specification does not release the Contractor from verifying that the actual as- supplied material batch or lot used for the specific project is in compliance with the requirements of this specification as well as current applicable codes and regulations.
