CLEAR ROADS SNOW AND ICE CONTROL CHEMICAL PRODUCT PROGRAM 1

Introduction and Purpose

Introduction

Clear Roads provides guidance and administration of the Qualified Products List (QPL), which was originally established through the Pacific Northwest Snowfighters. The QPL was created to review, test, and approve products used for winter maintenance and to provide guidance in the selection and purchasing of environmentally responsible products.

Clear Roads is a national research consortium consisting of several state departments of transportation.

Its focus is to fund research and technology transfer efforts in relation to winter maintenance materials, equipment, and methods.

Purpose

The purpose of this document is to define the submittal and maintenance process for the QPL, provide product specifications and testing protocol, and to provide guidance on purchasing winter maintenance products.

CLEAR ROADS SNOW AND ICE CONTROL CHEMICAL PRODUCT PROGRAM 2

QPL Process

Overview

The QPL is composed of products that have been tested and found to be in conformance with the specifications found in Table 1, and all other necessary product or testing documentation (e.g., Table 2 for liquid products or products intended to be applied as liquid). Clear Roads reserves the right to deny qualification based on all product information provided. Though the information required for “informational purposes” doesn’t have set parameters, the tests may reveal information about a product that requires further attention or inquiry.

All products submitted for inclusion on the QPL shall be tested by an independent laboratory and the results shall conform to the specified limits contained within Table 1 and Table 2, as appropriate, and test results sent to Clear Roads. Once a product passes the required specification testing limits and has passed the Clear Roads review, Clear Roads will request any additional information including vendor product samples. Once product samples are received, Clear Roads will conduct appropriate Quality Assurance testing. If QA testing is satisfactory and field testing is deemed unwarranted, the product shall be listed on the Clear Roads QPL. Figure 1 on page 3 details the process in a flowchart.

Incomplete submittals will not be reviewed. Clear Roads will review submitted paperwork in a timely manner and report discrepancies. It is not the role of Clear Roads to do a complete review and find all things erroneous about a product. For example, if a solid doesn’t meet the gradation specification, it will be denied and no assurance that any other parameter is met or not met will necessarily be provided. It is prudent that vendors are familiar with the specifications and check their product against the specifications prior to submittal. A product that fails to meet the standard limits as specified will be failed.

Clear Roads has the right to qualify or disqualify, accept, or reject products based on the materials used to produce the product. The products will be assessed for the potential of causing a decrease in the public safety or risk to the environment. The right to qualify or disqualify, accept, or reject a product based on manufactured composition rest solely with Clear Roads. The Clear Roads assessment shall be final and in the best interest of Clear Roads.

Any material changes to a product that is listed on the QPL by either the manufacturer or the vendor, which in any way makes the product different from the original qualified material, shall be grounds for disqualifying the product from the list. The new product will have to be re-qualified before it will be placed back on the QPL.

Each vendor submitting a sample will be notified whether the sample passes or fails to meet the specifications. Copies of the complete lab reports will be available upon request.

CLEAR ROADS SNOW AND ICE CONTROL CHEMICAL PRODUCT PROGRAM 3

Figure 1. QPL Submittal Process

CLEAR ROADS SNOW AND ICE CONTROL CHEMICAL PRODUCT PROGRAM 4

Submittal Process

Manufacturers/vendors will use the on-line submittal form on the Clear Roads Website to request a product be listed on the QPL.

Information required to complete the form:

(1) Product data/information sheet.

(2) Third party laboratory test results.

(3) Safety data sheet (for product and inhibitor, as appropriate).

(4) Proprietary information (if applicable); proprietary information will be held confidential by the Clear Roads QPL. Required documentation (test results, etc.) must be included in the on-line submittal, must be legible and clearly identify the product, and will be matched up to the product sample submittal when that is requested.

Test results are required to be entered on the on-line form. When inputting values that are less than the test detection limit you should enter “0.”

Review Procedures

Clear Roads will be alerted when a form is submitted online and will review the submission for completeness.

(1) Vendor/manufacturer will be notified by Clear Roads that information received is either complete or incomplete.

(2) If incomplete, vendor/manufacturer will be required to resubmit the form and documents for review.

Information received will be reviewed against the product category specifications.

(1) If the information provided indicates the product meets specifications, Clear Roads will request a product sample from the vendor/manufacturer for Clear Roads QA testing. See Section 1.4 for product sample submittal details.

(2) If information provided indicates the product doesn’t meet specifications, it will be rejected.

The vendor/manufacturer will receive notification from Clear Roads that the product failed to meet specifications and resubmittal is required for placement on the QPL.

Clear Roads QA test results will be reviewed against the product category specifications.

(1) If QA testing indicates the product meets specifications, the vendor/manufacturer will be notified that the product meets specifications and will be asked to review the QPL listing prior to posting.

(2) If QA testing indicates the product does not meet specifications, the vendor/manufacturer will be notified that the product has failed and will not be listed on the QPL.

Product Sample Submittals & QA Testing

Clear Roads has the right to test for verification or to accept the product as qualified based on the documentation submitted. When a product sample is requested by Clear Roads, two one-gallon samples of the product shall be sent to a lab as instructed by Clear Roads. Information noted below should be included when product samples are submitted:

https://www.clearroads.org/qpl-submission-form/

CLEAR ROADS SNOW AND ICE CONTROL CHEMICAL PRODUCT PROGRAM 5

(1) A copy of the Safety Data Sheet (SDS) must be included with all product samples to be considered for the QPL.

(2) Product samples must be properly contained and sealed to prevent leakage or spillage.

Samples not properly contained will be rejected.

(3) Product samples must be clearly labeled to identify the product and to match product samples to the online submittal documentation.

Clear Roads will conduct QA testing on sample submittals to verify submitted documentation by vendor/manufacturer. Results of the QA testing shall be verifiable and final.

All Clear Roads QA test results will be kept on file and will be used to establish product information as appropriate. If Clear Roads QA testing is different than test results provided by the vendor/manufacturer, the Clear Roads test results will be the official record of product specifications.

Field Verification

Most products will not require field verification testing by Clear Roads. Field performance should be relatively predictable based on the percentage of the active chemical constituent. If vendor/manufacturer is claiming a unique application method or rate, Clear Roads may require field testing to verify product safety and effectiveness.

The decision as to whether or not to require a supplier to furnish an ample supply of their product (at no charge including shipping) for field-testing lies solely with the Clear Roads.

If the product requested for field-testing is not furnished, or if an inadequate amount is supplied, or if product performance is not satisfactory, the product will not be placed on the

QPL.

QPL Management

Purchased products that appear on the QPL may be tested for compliance to the material that was originally submitted for qualification. The purchaser has the right to conduct this testing at its own will.

The most current QPL can be viewed at the Clear Roads website or by contacting one of the Clear Roads QPL members.

Expiration

Listing on the Clear Roads QPL will expire 5 (five) years from the QPL approval on December 31st of the expiration year. If the producer wants their product to remain on the Clear Road QPL beyond the expiration date, they can submit a letter to the QPL subcommittee’s chemists stating the product still meets specifications, is still being produced, and that the formulation hasn’t changed. If there are no concerns from the QPL committee the product will be remain on the QPL until the next expiration date at which time this process can be repeated. The committee may request product samples for testing.

Random Testing and Auditing

The Clear Roads QPL reserves the right to sample materials on the QPL for testing and to perform audits of test reports. Clear Roads and its representatives may sample material from the manufacturing plant, the member state sites, and other locations. Clear Roads reserves the

CLEAR ROADS SNOW AND ICE CONTROL CHEMICAL PRODUCT PROGRAM 6

right to test samples to verify compliance with these specifications. Producers must maintain a complete record of all test reports for the previous two years and current calendar year.

Product Name Changes, Producer Changes

If a product name changes but is produced by the same producer in the same manner when first qualified, then the producer will submit a letter to the QPL subcommittee verifying the new products name and that it still meets the Clear Roads QPL Specifications. If the producer changes its name but the product is still produced in the same manner when first qualified, then the producer will submit a letter to the QPL subcommittee verifying the new producer name and that it still meets the Clear Roads QPL Specifications. If a different producer is producing a qualified product, then that producer shall submit the product for QPL review.

Product Formulation Modification

If a product currently listed on the QPL is modified, the product must be resubmitted for approval on the QPL, with the accompanying Product Sample Checklist. Exceptions to this rule may be considered upon request.

Disqualification

Products that are found to be non-compliant with Clear Roads specifications may be removed from the QPL at any time. Additionally, if member states’ testing results are greater than a 10% failure rate in a year and confirmed by third-party testing, the member states can submit those results to the QPL subcommittee for disqualification. The QPL subcommittee will provide in writing reasons for disqualification. These items will remain unlisted until adherence to the specifications can be verified.

Documentation Management

Documentation submitted to Clear Roads is kept on file electronically. Proprietary information may be viewed by the QPL primary reviewer and the chemists testing the product samples.

Proprietary information otherwise is not shared.

Non-proprietary information provided to Clear Roads may be shared and viewed for research purposes. However, the main purpose of product information sent to Clear Roads is to verify that specifications are met, not necessarily to make documents available for research.

Public requests for product information received by Clear Roads will be re-directed to the product manufacturer. No information is provided to the public from Clear Roads about product test results other than what is published on the QPL listing.

CLEAR ROADS SNOW AND ICE CONTROL CHEMICAL PRODUCT PROGRAM 7

General Specifications This section provides the product specifications. Products that contain any constituent in excess of the following established total concentration limits (as tested in accordance with the listed test methodology from Section 3) will not be acceptable.

Liquid products shall be tested as received. Solid salts are to be diluted to a 25% (W/V) concentration and then tested as if the material was a liquid sample. Report only the values determined from the 25% solution for all the parameters as compared to the specification limits. Do not back calculate the concentration of the parameters to the dry weight of the material.

All liquid deicers must successfully complete the National Association of Corrosion Engineers (NACE) Standard TM0169-95, as modified by Clear Roads, and found to have a Corrosion Value of at least 70% less than that of Sodium Chloride (salt).

Section 2.1 contains Table 1, which lists the general specification limits, which are applicable to all products on the QPL. Section 2.2 contains Table 2, which lists the informational requirements for the liquid products and solids products to be used as liquids for application purposes. Section 2.3 provides category-specific specifications.

Specified Limits

Table 1. Specification and Method of Determination

Test Specified Limits Method Name

Corrosion Rate (corrosion inhibited products only) varies1 Test Method 5

Phosphorus ≤ 2500. ppm Test Method 7 Cyanide2 ≤ 0.20 ppm Test Method 8 Arsenic ≤ 5.0 ppm Test Method 9 Barium ≤ 100.0 ppm Test Method 9

Cadmium ≤ 0.20 ppm Test Method 9 Chromium ≤ 1.0 ppm Test Method 9

Copper ≤ 1.0 ppm Test Method 9

1 All liquids and liquids intended to be applied as solids must be at least 70% less corrosive than sodium chloride and have a corrosion effectiveness rate of 30% or less. For corrosion inhibited solids, refer to the product category specifications.

2 Salt for highway use is usually treated with either Ferric Ferrocyanide, also known as Prussian Blue, or Sodium Ferrocyanide, also known as Yellow Prussiate of Soda (YPS), to prevent the salt from caking. The amount of Prussian Blue added is 70 to 165 parts per million (ppm), equivalent to 0.33 to 1.14 pounds per ton of salt. YPS is added in the amount of 50 to 250 ppm, equivalent to 0.1 to 0.5 pounds per ton of salt. YPS is also used as an anti-caking agent in table salt, and has approval of the U.S. Food and Drug Administration. Based on exhaustive testing no evidence of toxicity was demonstrated. If used, the presence of these products will not be assessed towards the total cyanide concentration when testing this product. However, the total cyanide concentration of the original material must meet specifications.

Vendor may bid this product with or without the anti-caking agent. Vendors must note on the Sample Checklist if the sample does contain anti-caking agent or not, and if so, what type. If the Vendor chooses not to add the anti-caking agent it does not prevent the vendor from assuring that the delivered product is in a free-flowing state.
