The Environmental Protection Agency is widely expected to announce plans to change the definition of which waters in the United States are protected under the Clean Water Act on Tuesday -- a change President Donald Trump has been working toward since the beginning of his presidency.The EPA released a statement saying it would make a major water policy announcement on Tuesday.The announcement is expected to be a policy shift from former President Barack Obama's 2015 Waters of the United States regulation. Obama's rule changed the definition of which bodies of water the federal government had authority over to include streams and wetlands so that the government could ensure that those waterways remained pollution-free. It altered the definition from the initial one established by the EPA and Army Corps of Engineers in the 1980s.Obama's regulation was created under the Clean Water Act, which regulates discharges of pollutants into waters in the US. Under the Clean Water Act, it's illegal to discharge pollutants from a source into "navigable waters," according to the EPA. 1092

The CDC is now recommending “universal mask use” both indoors and outdoors whenever someone is not at their own home. This is the first time the agency has included indoor spaces in their recommendations for universal mask wearing.It comes as coronavirus cases in the U.S. continue to surge past 14 million positive cases and deaths climb above 277,000, with many states only beginning to see a potential second spike from Thanksgiving celebrations.In the CDC’s weekly report, they said with more time spent indoors with the colder weather, the ongoing holiday season and silent spread of the disease with about 50 percent of transmission happening from asymptomatic people, “the United States has entered a phase of high-level transmission where a multipronged approach to implementing all evidence-based public health strategies at both the individual and community levels is essential.”These include universal mask use, physical distancing, avoiding nonessential indoor spaces, increased testing, prompt quarantine, enhanced ventilation, and widespread vaccination coverage. The agency stresses “no single strategy can control the pandemic,” and all of these recommendations will be needed to break transmission chains.The CDC warns that indoor spaces and crowded outdoor spaces, especially where distancing is not maintained or consistent use of face masks is not possible, i.e. like when eating or drinking, “have been identified as particularly high-risk scenarios.”“Compelling evidence now supports the benefits of cloth face masks for both source control (to protect others) and, to a lesser extent, protection of the wearer,” the CDC guidelines now read. “Face mask use is most important in indoor spaces and outdoors when physical distance of ≥6 feet cannot be maintained. Within households, face masks should be used when a member of the household is infected or has had recent potential COVID-19 exposure.”Any indoor spaces should also have good ventilation, the CDC says. "For indoor settings, increased room air ventilation can decrease the concentration of small droplets and particles carrying infectious virus suspended in the air and, thereby, presumably decrease the risk for transmission."The World Health Organization recently updated their guidelines that everyone 12 and older should wear a mask outside, inside and even inside people’s own homes if they are poorly ventilated. They recommended that children ages 6-to-11 should wear a mask based on a “risk-based approach.”Earlier this week, the CDC said they recommend against traveling this holiday season to slow the spread of the coronavirus. They made a similar plea before Thanksgiving, however the TSA reported record-high airport screenings since the pandemic started. 2758

The coronavirus pandemic has had a big impact on businesses of all kinds, restaurants and retailers alike are closing permanently and others are doing what they can to financially survive.That also means it could be a good time for consumers looking for specific items to save some money.The website rather-be-shopping.com compiled a list of 13 items that have become cheaper during the pandemic.Items like clothing for the whole family. Retailers like Macy’s, Stein Mart, Ann Taylor, and many more are closing anywhere from several stores to most of them. That could mean deep discounts during liquidation sales.Those looking for a home or want to refinance will find low mortgage rates right now. Mortgage rates have hit an all-time low.Gas is about 50 cents cheaper nationally than it was in the summer of 2019. Maybe it’s time for a road trip or long drive and save on fuel prices.That also contributes to low shipping costs. Many online sites are offering no or low shipping costs right now.In time for school to start, technology is cheaper and many places are offering discounts on laptops and electronic devices and headphones that can be used for at-home learning. There are also 16 states with "no sales tax" weekends to encourage shopping. 1259

The Federal Aviation Administration has issued a safety alert about flying with dry ice onboard, in anticipation of the huge nationwide distribution project anticipated to start in the next few days once the Pfizer COVID-19 vaccine is approved for use.The Pfizer and Moderna vaccines both need to be kept at extremely cold temperatures, requiring the use of dry ice during transit.Dry ice is frozen carbon dioxide that is pressed into blocks or pellets. It doesn’t melt into a liquid, it moves directly from a solid to a gas and that process can happen quickly at high altitudes.That can cause problems onboard a plane, such as causing the plane to weigh less at times during the flight and change its center of gravity.“CO2 sensors installed or carried in the aircraft or worn by the pilots and other crewmembers will assist the operator and crew in recognizing hazardous concentrations of CO2 and implementing effective risk controls,” the FAA’s safety alert recommends.In addition, they encourage maximum ventilation onboard while on the ground and in the air, asking crewmembers to check air conditioning units and auxiliary power units before flight.Exposure to elevated levels of CO2 can cause drowsiness or dizziness, and higher levels can impact breathing eventually leading to hypoxia and death.The FAA also recommends that “pilot training on specific conditions and procedures can improve pilot decision-making in the event of a CO2 detector alert or other system abnormalities.”Friday morning, Health and Human Services Director Alex Azar said Americans could begin getting the COVID-19 vaccine next week once the FDA and CDC give it emergency use approval. 1676
