New permitting provisions in budget bill slight natural gas industry
(UI) — The natural gas industry greeted the permitting reform bill Congress passed, and President Biden signed last month with something short of enthusiasm. The permitting provisions in the Fiscal Responsibility Act of 2023 had only glancing benefits for gas pipelines and were chiefly written to benefit wind, solar and electric energy deployment.
Asset management: Digging data
(UI) — There are already lots of good reasons for why you should digitally document underground construction jobs, from pre-drill planning to post-drill reporting.
Inside infrastructure: Latest ‘WOTUS’ rule upended by Supreme Court
(UI) — Looking at the increasingly high-profile issue of permit reform needed to get important infrastructure projects off the ground, few issues (if any) are as polarizing as the “Waters of the Unites States” (WOTUS) rulemaking.
Hard surface potholing the right way helps a business grow
(UI) — More Florida cities are seeing the advantages of core saws, since McKim & Creed expanded into coring solid surfaces to locate utilities.
Exploring the future of the manhole camera industry: Unlocking hidden insights
(UI) — The manhole camera industry has undergone significant advancements in recent years, revolutionizing the way we inspect and maintain underground infrastructure.
NASSCO tech tips: PACPTM condition grading system
Each of NASSCO’S Pipeline Assessment Certification Program (PACP) inspection reports offer eight or nine different condition grades. How each of these condition ratings are calculated is outlined within the PACP Manual Appendix C, but what do they mean and how can they be interpreted?
Caverns of Calloway – Dirt pipes are expensive
(UI) — After a heavy rainfall in June 2022, the Trinity River Authority (TRA) was notified of a sanitary sewer overflow (SSO) on a sewer line within the Walker Calloway System, a 4.7-mile wastewater collection system built, owned and operated by TRA.
HDDA Mud School provides vital information to drillers
The Horizontal Directional Drilling Association recently held a complimentary, hands-on Mud School to share vital information for new drillers and provide a refresher course for veteran operators. More than 60 people attended the May 18 event held at the Doubletree Hotel near Love Field in Dallas, Texas.
Utility and communications construction update
As the construction season jumped into full swing, the impacts of labor, equipment and government regulation on the contractor are highly impactful. After another month in June of construction employment gains (25,000 new jobs) in the U.S. economy, the challenge of finding labor to complete the potential work remains high.
New leak detection rules for pipelines proposed
(UI) — The federal Pipeline and Hazardous Materials Safety Administration (PHMSA) has proposed major changes to its leak detection based not on concerns about safety but, rather, in order to reduce methane emissions related to their contribution to climate change.
Pressure pipe rehabilitation – what’s on the menu?
(UI) — Trenchless methods have been widely used for the rehabilitation of gravity pipelines for some time. The advent of these technologies and methods has lowered the cost of extending the useful life of gravity pipelines as opposed to outright replacing them.
Achieving more accurate utility infrastructure mapping with the help of an app
(UI) — More than 217,000 utility damage events were reported in 2021, according to the latest Common Ground Alliance DIRT (Damage Information Reporting Tool) Report. The three leading causes of these reported utility strikes were: digging without calling 811, failure to pothole and/or maintain clearance, and locating issues due to incorrect and/or outdated maps.
