Permanent paper: (A) A paper that can resist chemical and physical changes over an extended time period (several hundred years). This paper is generally acid free, has a fairly high initial strength, and will retain its strength over time. (B) The P.L. 101-423, Joint Resolution to Establish a National Policy on Permanent Paper, passed October 1990, states: ``It is the policy of the United States that Federal records, books, and publications of enduring value be produced on acid free permanent papers.'' Pick resistance: Use method T-459 (wax pick) for uncoated papers. Note: There is no standardized pick test for coated papers. PMU (phosphor meter unit): Specialized equipment for measuring this property available from the U.S. Postal Service. Porosity: Use method T-460. Postconsumer fiber: Pulp fiber derived from postconsumer recovered paper. Postconsumer material: ``(1) Paper, paperboard and fibrous wastes from retail stores, office buildings, homes and so forth, after they have passed through their end-usage as a consumer item including: Used corrugated boxes; old newspapers; old magazines; mixed waste paper; tabulating cards and used cordage; and (2) All paper, paperboard and fibrous wastes that enter and are collected from municipal solid waste.'' (40 CFR 247.3) Recovered material: Waste material and by-products that have been recovered or diverted from solid waste, but such term does not include those materials and by-products generated from, and commonly reused within, an original manufacturing process. In the case of paper and paper products, the term ``recovered materials'' includes: ``(1) Postconsumer materials such as: (i) Paper, paperboard, and fibrous wastes from retail stores, office buildings, homes, and so forth, after they have passed through their end usage as a consumer item, including: Used corrugated boxes, old newspapers, old magazines, mixed waste paper, tabulating cards, and used cordage, and, (ii) All paper, paperboard, and fibrous wastes that enter and are collected from municipal solid waste; and (2) Manufacturing, forest residues, and other wastes such as: (i) Dry paper and paperboard waste generated after completion of the papermaking process (that is, those manufacturing operations up to and including the cutting and trimming of the paper machine reel into smaller rolls or rough sheets) including envelope cuttings, bindery trimmings, and other paper and paperboard waste, resulting from printing, cutting, forming, and other converting operations; bag, box and carton manufacturing wastes; and butt rolls, mill wrappers, and rejected unused stock; and (ii) Finished paper and paperboard from obsolete inventories of paper and paperboard manufacturers, merchants, wholesalers, dealers, printers, converters, or others; (iii) Fibrous by-products of harvesting, manufacturing, extractive, or wood-cutting processes, flax, straw, linters, bagasse, slash, and other forest residues; (iv) Wastes generated by the conversion of goods made from fibrous material (e.g., waste rope from cordage manufacture, textile mill waste, and cuttings); and (v) Fibers recovered from waste water that otherwise would enter the waste stream.'' (40 CFR 247.3) Recovered Materials Advisory Notice (RMAN): EPA guidance regarding certification and verification of the use of recovered fiber in printing and writing papers clarifying section 6002(i)(2)c of the Resource Conservation and Recovery Act (RCRA) of 1976.
