4.1 Uses—This classification is intended for use by federal landholding agencies and DoD components in order to direct ECOP efforts. It is also intended for use by preparers and reviewers of environmental condition of property maps, explosives safety condition maps, and ECOP reports used to support CERFA uncontaminated parcel identifications and parcels suitable for transfer by lease or by deed. This classification should be used to facilitate standardized determinations of the environmental condition and explosives safety conditions of a federal landholding agency, FUDS, and DoD installation's real property. Such environmental condition of property and explosives safety condition determinations are necessary to assess the progress of ongoing environmental restoration, identify areas where further response may be required, identify areas where further evaluation is necessary, and to support FOSTs and FOSLs. An environmental condition of property map, and explosives safety condition map, if applicable, based upon the ECOP report prepared in accordance with Practice D6008, is prepared using this classification. The ECOP report may be used to determine the MILCON category (see Section 8 and Table X1.1 in Appendix X1).1.1 Purpose—The purpose of this classification is to define eight standard environmental condition of property area types for federally-owned real property with respect to the requirements of the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA) of 1980 Section 120(h), as amended by the Community Environmental Response Facilitation Act (CERFA) of 1992, and Section 331 of the National Defense Authorization Act for Fiscal Year 1997. As such, this classification is intended to permit a federal landholding agency to classify property into eight area types, in order to facilitate and support findings of suitability to transfer (FOSTs), findings of suitability to lease (FOSLs), and uncontaminated parcel determinations pursuant to the requirements of CERFA. Users of this classification should note that it does not address (except where noted explicitly) requirements for appropriate and timely regulatory consultation or concurrence, or both, during the identification and use of these environmental condition of property area types.1.1.1 Eight Recognized Standard Environmental Condition of Property Area Types—The goal of this classification is to permit federal landholding agencies to classify properties in order to support determinations of which properties are suitable and unsuitable for transfer by lease or by deed. The term “standard environmental condition of property area type” refers to one of the eight area types defined in this classification. An identification of an area type on an environmental condition of property map means that a federal landholding agency federally-owned has conducted sufficient studies to make a determination of the recognized environmental conditions of installation real property or has complied with the identification requirements of uncontaminated property under CERFA, or both, and has categorized the property into one of the following eight area types:1.1.1.1 Standard Environmental Condition of Property Area Type 1—An area or parcel of real property where no release, or disposal of hazardous substances or petroleum products or their derivatives has occurred (including no migration of these substances from adjoining properties).1.1.1.2 Standard Environmental Condition of Property Area Type 2—An area or parcel of real property where only the release or disposal of petroleum products or their derivatives has occurred.1.1.1.3 Standard Environmental Condition of Property Area Type 3—An area or parcel of real property where release, disposal, or migration, or some combination thereof, of hazardous substances has occurred, but at concentrations that do not require a removal or remedial action.1.1.1.4 Standard Environmental Condition of Property Area Type 4—An area or parcel of real property where release, disposal, or migration, or some combination thereof, of hazardous substances has occurred, and all remedial actions necessary to protect human health and the environment have been taken.1.1.1.5 Standard Environmental Condition of Property Area Type 5—An area or parcel of real property where release, disposal, or migration, or some combination thereof, of hazardous substances has occurred and removal or remedial actions, or both, are under way, but all required actions have not yet been taken.1.1.1.6 Standard Environmental Condition of Property Area Type 6—An area or parcel of real property where release, disposal, or migration, or some combination thereof, of hazardous substances has occurred, but required response actions have not yet been initiated.1.1.1.7 Standard Environmental Condition of Property Area Type 7—An area or parcel of real property that is unevaluated or requires additional evaluation.1.1.1.8 Standard Environmental Condition of Property Area Type 8—An area or parcel of real property where the release, disposal, or migration, or some combination thereof of hazardous substances or emerging contaminants of environmental concern has likely occurred, but response actions either (1) have not yet been determined, or (2) are being managed under the auspices of an ARAR, such as a federal or state health advisory, or other federal regulatory program such as the Toxic Substances Control Act (TSCA).1.1.2 CERCLA Section 120(h) Requirements—This classification of environmental condition of property area types is consistent with CERCLA § 120(h) requirements relating to the transfer of contaminated federal real property (42 USC 9601 et seq.). Areas classified as Area Types 1 through 4, as defined in this classification, are suitable, with respect to CERCLA § 120(h) requirements, for deed transfer to a non-federal recipient.1.1.3 CERFA Requirements—This classification of environmental condition of property area types can be used in conjunction with the reporting requirements of CERFA, which amended CERCLA (Public Law 102-426, 106 Statute 2174). As defined in this classification, areas classified as Type 1 areas are eligible for reporting as “uncontaminated property” under the provisions of CERFA. At federal installations listed on the national priorities list, Environmental Protection Agency (EPA) concurrence must be obtained for a parcel to be considered uncontaminated and therefore transferable under CERCLA § 120(h)(4). EPA has stated as a matter of policy that there may be instances in which it would be appropriate to concur with the military service that certain parcels can be identified as uncontaminated under CERCLA § 120(h)(4), although some limited quantity of hazardous substances or petroleum products have been stored, released, or disposed of on the parcel. If the information available indicates that the storage, release, or disposal was associated with activities that would not be expected to pose a threat to human health or the environment (for example, housing areas, petroleum-stained pavement areas, and areas having undergone routine application of pesticides), such parcels should be eligible for expeditious reuse.1.1.4 Petroleum Products—Petroleum products and their derivatives are included within the scope of this classification. Under existing agency-specific and US EPA policy, areas on which petroleum products and their derivatives have been released or disposed of may not be suitable for deed transfer until a response action has been completed.1.2 Objectives—The objectives guiding the development of this classification are as follows: (1) to synthesize and put in writing a standard classification of environmental condition of property area types; (2) to facilitate the development of high-quality, standardized environmental condition of property maps that can be used to support FOSTs and FOSLs; (3) to facilitate the development of a standard practice for conducting environmental baseline surveys; and (4) to facilitate the development of a standard guide for preparing environmental baseline survey reports.1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

3.1 The compression resistance perpendicular to the faces, the resistance to the extrusion during compression, and the ability to recover after release of the load are indicative of a joint filler's ability to continuously fill a concrete expansion joint and thereby prevent damage that might otherwise occur during thermal expansion. The asphalt content is a measure of the fiber-type joint filler's durability and life expectancy. In the case of cork-type fillers, the resistance to water absorption and resistance to boiling hydrochloric acid are relative measures of durability and life expectancy.NOTE 2: The quality of the results produced by this standard are dependent on the competence of the personnel performing the procedure and the capability, calibration, and maintenance of the equipment used. Agencies that meet the criteria of Specification D3666 are generally considered capable of competent and objective testing, sampling, inspection, etc. Users of this standard are cautioned that compliance with Specification D3666 alone does not completely ensure reliable results. Reliable results depend on many factors; following the suggestions of Specification D3666 or some similar acceptable guideline provides a means of evaluating and controlling some of those factors.1.1 These test methods cover the physical properties associated with preformed expansion joint fillers. The test methods include:  Property SectionExpansion in Boiling Water 7.1Recovery and Compression 7.2Extrusion 7.3Boiling in Hydrochloric Acid 7.4Asphalt Content 7.5Water Absorption 7.6Density 7.7NOTE 1: Specific test methods are applicable only to certain types of joint fillers, as stated herein.1.2 The values stated in inch-pound units are to be regarded as standard.
