Indoor air quality -- another way of saying mold -- is providing a lot of employment for legislators. Mold bills are proliferating this year like, well, mold. Some 60 pieces of indoor air quality related legislation have come before 27 state legislatures this year, according to Aerias, an online resource for indoor air quality issues. Of those, 23 deal with mold occurring in homes and their remedy.

So far this year, eight states -- including Arizona, Idaho, Illinois, Louisiana, Nevada, Oklahoma, Tennessee, and Texas -- have passed 10 bills that address residential mold and mold remediation, Aerias reports: four have failed and nine are still pending. Of the 10 that passed, four deal directly with the licensing of mold assessors and remediators.

Meanwhile, states are also considering another 22 bills addressing mold and mold remediation in schools and 15 others affecting public buildings.

Connecticut led the pack with 10 bills, nine of which target schools. Texas, however, has passed the most legislation with the passage of three indoor mold bills. Texas joint resolution HB 329 and Senate Bill (SB) 243 will establish a licensing system for mold assessors and remediators. Licensing requirements could include a test and continuing education requirements for license holders. This bill was signed into law on June 11, 2003.

Texas HB 730 requires that the Texas Residential Construction Commission adopt limited statutory warranties and building and performance standards for residential construction, including standards for mold reduction and remediation. This bill also creates a mold reduction and remediation task force that would develop measures to reduce exposures to mold.

A Texas House Concurrent Resolution requests that the Congress of the United States pursue research to quantify health risks and develop uniform exposure guidelines for molds and mold groupings that contribute to sick buildings.

This bill was signed into law on June 20 and became effective on Sept. 1, 2003.
