The telecommunications and associated services have seen a remarkable change and progress since the 1990's, so much so that the phones as the main instrument have changed to a degree that has been a thing of sci-fi movies.
Until the 1990's, the telecommunication was using static phones and wires that were connecting them to the network, and that was it, there was no other function. Than in the 1990's, the first mobile phones were invented, and the era of wireless communication started. The mobile phones, at the start, had the same function as the static phones, but they had huge advantage that you were able to carry them around with you wherever you go. As the time passed, the mobile phones were developing more and more, and games, calculators, and multiple other basic things were included on them. Than on the scene appeared the androids and the IPhones. They were not using buttons anymore, but instead everything was on touch. Numerous applications were included, excellent hard drives and software, large memory capacity, and the phones became literary a mini computers that can be used for pretty much everything, giving no signs whatsoever that until very recently their ancestors where static and had only one function.

Answer: At the federal level, environmental statutes establish standards that may be enforced by federal administrative agencies or by state agencies implementing federally approved state programs. State standards are sometimes more stringent than required by federal law, but they are never more lenient.
Explanation: For example, states may choose to establish and enforce their own programs consistent with the Clean Air Act (CAA) and the Clean Water Act (CWA). If they do not, those standards will be enforced by the U.S. Environmental Protection Agency (EPA), which also enforces the Resource Conservation and Recovery Act (RCRA), and the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA or Superfund). All of these laws are explained in greater detail on the EPA website, which also contains links to corresponding state laws. The National Historic Preservation Act (NHPA) establishes incentives to protect historic and cultural resources, while state and local historic preservation laws may actually restrict physical changes to property.
