SUPPLEMENTARY INFORMATION:

1. Background

   Since December of 2008, the Commission has been receiving reports of various problems related to drywall primarily imported from the

   People's Republic of China. The first reports came primarily from

   Florida and were related to the building boom and post-hurricane construction. As reports continued to come in, it became apparent that the drywall issue was more widespread. Currently, CPSC has received over 2000 incident reports from 32 States, the District of Columbia and

   Puerto Rico. The Commission has expanded its investigation to include both imported and domestically manufactured drywall.

   Problems described in these reports include odor, health effects and corrosion effects on certain metal components in the home. The most frequently reported health symptoms are irritated and itchy eyes and skin, difficulty in breathing, persistent cough, bloody noses, recurrent headaches, sinus infection, and asthma attacks. Many reports indicate that the symptoms lessen when the consumer is away from home.

   As for corrosion-related effects, consumers have reported blackened and corroded metals and electrical wiring in their homes and failures of such equipment as evaporator coils of central air conditioners. There have also been reports of failures of appliances such as refrigerators and dishwashers, and of electronic devices such as televisions and video game systems.

   CPSC is investigating the health effects and the potential electrical and fire safety issues stemming from the corrosion of metal equipment and components. CPSC is working with a number of state and federal partners in this investigation including the U.S. Environmental

   Protection Agency, U.S. Department of Housing and Urban Development,

   Centers for Disease Control, Agency for Toxic Substance and Disease

   Registry and several state departments of health and state attorneys general. In the course of this investigation, Commission staff has visited several U.S. and Chinese drywall manufacturing facilities and mines. CPSC staff is analyzing information received from consumers, builders, importers, manufacturers and suppliers of drywall to better determine the scope of the drywall problem. CPSC and its state and federal partners are conducting a number of technical studies to determine connections between the emissions from drywall and the reported health and corrosive effects.

   CPSC's investigation indicates that it is often difficult to determine the manufacturer and origin of drywall in homes. As further discussed in the next section, the investigation also indicates that there can be a good deal of variability in drywall depending on its type and origin. Being able to identify the manufacturer and origin of drywall could aid in investigating complaints related to drywall and narrow the scope of any investigation or necessary remedial action in the future.

2. The Product

   Drywall, sometimes also called gypsum board, plasterboard or wallboard, is a kraft paper liner wrapped around a plaster mix consisting primarily of gypsum. There are essentially two types of gypsum: Mined gypsum; and synthetic gypsum. These two types are sometimes combined.

   Mined gypsum is found in sedimentary rock formations among limestone, shale, marl and clay. Characteristics of the mined gypsum can vary depending on the geology in the region where it is mined or quarried. Nearby sulfur deposits and marine conditions may affect the quality of the gypsum.

   Synthetic gypsum is an alternative to natural mined gypsum. It is a byproduct generated from flue gas desulfurization (``FGD'') in fossil- fueled power plants.

   There can be variability in gypsum depending on where it is mined and the manufacturing process employed. Gypsum mined in some areas may have higher levels of sulfur, strontium, carbonate, or pyrite; some of these chemicals could affect drywall's behavior in homes. Similarly, some flue gas sources may have higher or lower concentrations of these and other compounds.

   There are eight domestic drywall manufacturers in the United

   States, with plants spread throughout the country and North America.

   Two domestic manufacturers are ranked among the top five drywall producers in the global market. In 2008, the United States drywall production totaled an estimated 26.4 billion square feet. In 2006, the total domestic production of 35.0 billion square feet was not enough to meet demand that year. As a result, parties found themselves importing drywall from China and other countries to meet construction needs. In 2006, approximately 218,100 metric tons of drywall was imported from

   China.

   The drywall manufacturing process is rather standard throughout the industry. To make drywall, the raw gypsum (whether mined, FGD or a combination) is dehydrated (sometimes called ``calcined''), typically with natural gas. A slurry is made consisting of gypsum and additives such as fiber (typically paper and/or fiberglass), plasticizer, foaming agent, potash as an accelerator, water, ethylenediaminetetra acetic acid or other chelate as a retarder. The additives are based on whether the drywall is to be standard, fire resistant, or mildew or water resistant. The slurry is fed between continuous layers of paper on a board machine. As the board moves down a conveyer line, the mixture hardens. The paper becomes bonded to the solid slurry mix. The board is then cut to requested lengths and conveyed through dryers to remove any free moisture. The lengths and thickness of the board vary depending on the typical building code or usage requirements.

   At a certain point along the conveyer line, most domestic manufacturers mark the board with a stamp which may include the company name, logo, brand name, plant location, production date, and time.

   However, this practice is not standard for every drywall manufacturer in the global marketplace.

3. Need for Better Identification of Drywall

   CPSC's investigation has shown that building supply companies often stock drywall based on purpose, type, length and thickness, rather than brand name. Therefore, various drywall brands could be sold to fill a single construction project order. Since construction customers generally do not inventory drywall based on brand or country of origin it makes identifying the source/manufacturer of the drywall difficult once the product is installed.

   In the course of its investigation, CPSC staff has found that drywall often lacks any marks on its face or backing identifying the manufacturer or the production batch or lot. Identifying markings on the drywall could help consumers and investigators to isolate the source of drywall problems in the future. Being able to identify the brand and lot or batch could further narrow the focus of an investigation to discrete sets of drywall. The majority of imported drywall has little or no markings at all on its face. Most domestic drywall has markings that identify the manufacturer. Any markings that are present on domestic or imported drywall whether on the board or tape are inconsistent as to both content and placement. Most drywall is sealed on the ends with tape that displays a brand name or manufacturer's name. During the installation process, however, that tape is often removed.

4. Statutory Authority

   Section 14(c) of the CPSA authorizes the Commission to issue a rule requiring labels (and prescribing their form and content) containing source information, such as date and place of manufacture of a consumer product, cohort information (including batch, run number or other identifying characteristic), and identification of the manufacturer or private labeler. 15 U.S.C. 2063(c).

   Section 14(c) allows the Commission, where practicable, to require that the identifying labels be permanently marked or affixed to the product. Id. Such an identifying permanent mark would be consistent with section 103 of the Consumer Product Safety Improvement Act, entitled ``Tracking Labels for Children's Products,'' which requires

   ``permanent distinguishing marks'' stating certain identifying information on children's products and their packaging. Section 14(c) of the CPSA also authorizes the Commission to permit information about the date and place of manufacture and cohort information to be coded. 15 U.S.C. 2063(c).

   The Commission is considering a rulemaking that would require manufacturers of drywall to label/mark their products to identify (1)

   The name of the manufacturer; (2) the plant name and location; (3) the source material (i.e., natural gypsum, synthetic gypsum or a mixture);

   (4) a code to identify the mine or power plant that supplied the gypsum; (5) the date of manufacture of the drywall; and (6) the batch or lot number.

   The Commission requests comments on such a requirement and on the specific issues mentioned in the following section. If the Commission were to initiate such a rulemaking, it would do so with the issuance of a notice of proposed rulemaking.

5. Request for Comments

   The Commission requests comments on the possibility of initiating a rulemaking proceeding to require identifying labels on drywall.

   Specifically, the Commission requests comments and information on the following specific issues: 1. What labeling or markings are companies currently providing on drywall? 2. What would be the cost impact if the Commission were to require identifying labels/markings of the type discussed in this notice on drywall? 3. What, if any, other identifying information should be required? 4. Should there be a uniform format for the labels/markings, and if so, what should it be? 5. How can CPSC assure that the identifying label/marking is accessible after the drywall is installed? 6. What would the impact be on industry of requiring identifying information to be printed on both faces of the drywall in two horizontal ribbons parallel to the longitudinal axis with a

   Page 66624

   frequency that is a non-integer of 16 inches? 7. If the Commission were to define `drywall' for tracking labels, or other purposes, what should such a definition include? 8. With what specificity should drywall manufacturers identify the

   `date of manufacture,' and why?
