Colorado and Texas adopted rules Tuesday that require oil and natural-gas companies to disclose the chemicals they inject underground in the drilling technique known as fracking.
The rules are part of a broader effort by states to show they are serious about regulating the rapidly expanding hydraulic fracturing ahead of possible new federal rules governing chemical disclosure, water disposal, air emissions and well construction.
Next month, the federal government is expected to issue guidelines for disposal of water used in fracking, and the Interior Department later will publish rules governing such operations on public lands.
