IAPMO Commends Washington State Legislature’s Passage of Bill Requiring Testing Water for Lead in Schools and Day-Care Facilities
IAPMO commends the Washington State Legislature for passing HB 1139, a bill that requires the Washington Department of Health (DOH) to test drinking water outlets for lead contamination in public elementary and secondary schools. Gov. Jay Inslee signed the bill into law Monday.
The Biden administration recently announced a plan for the nationwide removal of lead pipes, and HB 1139 takes an additional step to support lead reduction in schools’ drinking water by mandating the repair or replacement of fixtures where elevated lead is found.
As noted in the bill, the DOH sampled and tested drinking water outlets in 551 elementary schools between 2017 and 2020 and found that 82 percent of these schools had lead contamination of five or more parts per billion in one or more drinking water outlets. Further, 49 percent of these schools had lead contamination of 15 or more parts per billion in one or more drinking water outlets.

Seattle Adopts Provisions of 2018 Uniform Plumbing Code
The city of Seattle has formally adopted the 2018 Seattle Plumbing Code (SPC), which is based on IAPMO’s 2018 Uniform Plumbing Code (UPC®), updating from the 2015 edition. It is available for purchase from the IAPMO Online Store.

The 2018 edition of the SPC is a custom plumbing code published for the city of Seattle. It also protects against hazards that may arise from the use of plumbing piping and systems by regulating and controlling the design, construction, installation, quality of materials, location and operation of plumbing piping systems within the city of Seattle. The code includes the Washington state and Seattle amendments integrated into the 2018 UPC. This edition also includes the new Water Demand Calculator for estimating water supply demand and pipe sizing.
EPA Moves Forward with Phase Down of Climate-Damaging Hydrofluorocarbons
The U.S. Environmental Protection Agency (EPA) is proposing its first rule under the American Innovation and Manufacturing (AIM) Act of 2020 to phase down the production and consumption of hydrofluorocarbons (HFCs), highly potent greenhouse gases commonly used in refrigerators, air conditioners, and many other applications. The AIM Act directs EPA to sharply reduce production and consumption of these harmful pollutants by using an allowance allocation and trading program. This phasedown will decrease the production and import of HFCs in the United States by 85% over the next 15 years. A global HFC phasedown is expected to avoid up to 0.5 °C of global warming by 2100.

“With this proposal, EPA is taking another significant step under President Biden’s ambitious agenda to address the climate crisis,” said EPA Administrator Michael S. Regan. “By phasing down HFCs, which can be hundreds to thousands of times more powerful than carbon dioxide at warming the planet, EPA is taking a major action to help keep global temperature rise in check. The phasedown of HFCs is also widely supported by the business community, as it will help promote American leadership in innovation and manufacturing of new climate-safe products. Put simply, this action is good for our planet and our economy.”

Construction Starts Increase in March, but Rising Material Prices Could Hamper Recovery
A strong pickup in nonresidential building overpowers weakness elsewhere
Total construction starts rose 2% in March to a seasonally adjusted annual rate of $825.3 billion, according to Dodge Data & Analytics. A solid gain in nonresidential building starts fueled the March gain, while growth in residential starts was minuscule and nonbuilding starts fell outright. The Dodge Index rose 2% in March, to 175 (2000=100) from February’s 172.

“The March increase in construction starts is certainly welcome news following the past three months of decline,” said Richard Branch, Chief Economist for Dodge Data & Analytics. “Construction will continue to improve as the year moves on. However, just as the pandemic is beginning to loosen its grip on the economy, logistical problems and the rapid escalation in material prices have stepped in as the primary risk to the construction sector. These issues may restrain opportunity in the coming months, causing the sector’s recovery to lag that of the overall economy.”
Faster Air Exchange in Buildings Not Always Beneficial for Coronavirus Levels
Vigorous and rapid air exchanges might not always be a good thing when it comes to addressing levels of coronavirus particles in a multiroom building, according to a new modeling study.
The study suggests that, in a multiroom building, rapid air exchanges can spread the virus rapidly from the source room into other rooms at high concentrations. Particle levels spike in adjacent rooms within 30 minutes and can remain elevated for up to approximately 90 minutes.
The findings, published online in final form April 15 in the journal Building and Environment, come from a team of researchers at the U.S. Department of Energy’s Pacific Northwest National Laboratory. The team includes building and HVAC experts as well as experts in aerosol particles and viral materials.
“Most studies have looked at particle levels in just one room, and for a one-room building, increased ventilation is always useful to reducing their concentration,” said Leonard Pease, lead author of the study. “But for a building with more than one room, air exchanges can pose a risk in the adjacent rooms by elevating virus concentrations more quickly than would otherwise occur.
Massive 300-ton Fatberg Blocks UK Sewer
Wet wipes and grease are being blamed for a massive 300-ton sewer blockage in Birmingham, UK. The “fatberg” may take over a month to clear. The solid mass is estimated to be 3ft high and 1,094yds long.
“This giant mass is the result of everyone occasionally washing and flushing the wrong things down the drains, and not realizing the impact that it’s having,” said Severn Trent operations manager Scott Burgin.
“The problem is that unlike toilet paper, wipes and other unflushables including nappies and sanitary products don’t break up or dissolve, so they easily get stuck in drains and sewers and then attach onto cooking oil and grease to create a fatberg.”
“Our advice is to always leave leftover cooking fat to cool, before disposing of it in the bin and to stick to only flushing the three P’s (pee, poo and toilet paper) and bin anything else.

“These relatively small changes can make a big difference and hopefully avoid any future fatbergs.”
