PA DEP Issues Permits for TETCO Appalachia to Market III Pipe
Last summer, Texas Eastern Transmission Pipeline Company (aka TETCO, owned by Enbridge) filed to build the Appalachia to Market III Project, abbreviated A2M III (see TETCO Files Appalachia to Market III, Small Pipe Tweaks in PA). A2M III is designed to provide additional natural gas supply in Pennsylvania and the broader region to meet growing demand from utilities and industrial users for Marcellus gas. The A2M III Project will provide up to 32,000 dekatherms per day (32 MMcf/d) of additional firm natural gas transportation service from the Appalachian supply basin in Southwest Pennsylvania to meet the needs of two existing local distribution company customers in Pennsylvania and Delaware. Over the weekend, the Pennsylvania Department of Environmental Protection (DEP) published a notice that it has issued requested water quality permits and approvals for the project.

Iroquois Gas Transmission’s Enhancement by Compression (ExC) project would increase horsepower at three compressor stations — two in New York and one in Connecticut — by an extra 125 MMcf/d, to flow more Marcellus/Utica gas into New York City and New England. The two NY compressors are in Dover and Athens. The CT compressor is located in Brookfield. In September, we told you that the Sierra Club paid for a fake study bashing the Connecticut portion of the project (see 
Another new (to us) pipeline project in the Southeast with the potential to flow Marcellus/Utica molecules. We recently became aware of Enbridge’s Texas Eastern Line 31 Expansion Project. The project is designed to expand the capacity of the Texas Eastern (TETCO) interstate natural gas system in Madison County, Mississippi. The current proposal (not yet officially filed with FERC) includes approximately 10.2 to 11.5 miles of 36-inch-diameter pipeline looping, a 1.7-mile delivery lateral, and the construction of the new Ridgeland Compressor Station. The project is expected to provide between 125,000 and 160,000 dekatherms per day (Dth/d) of additional natural gas transportation capacity, primarily intended to serve Entergy’s proposed Ridgeland Advanced Power Station (gas-fired power station) in Madison County. 
It’s always fun for us to discover a new pipeline project that has the potential to flow more Marcellus/Utica molecules to other markets—particularly the Southeast and Gulf Coast markets. Here is one such project that (until now) had escaped our notice. On Dec. 29, the Federal Energy Regulatory Commission (FERC) issued an Environmental Assessment (EA) for the Southeast Compression for Utility Reliability Expansion (SECURE) Project, a compressor-focused expansion project designed to enhance compression infrastructure across Mississippi and Louisiana for the Gulf South Pipeline Company. The project will expand the Gulf South Pipeline system to provide an extra 280,000 dekatherms per day (Dth/d) of firm natural gas transportation service (280 MMcf/d) to markets in the Southeast, including support for power generation customers. 
Natural gas markets have experienced plenty of changes over the past few years. Some of those changes include rising associated gas production in the Permian, new pipeline and storage capacity, new LNG demand, and gyrations in prices. However, an RBN Energy blog article argues that all this was merely a prelude. RBN says the “main event” — a veritable transformation of gas markets, especially along the Gulf Coast — is about to begin. Buckle up! What’s coming? A doubling of LNG demand (to 32 Bcf/d!). Another 10 Bcf/d of new pipelines out of West Texas, plus at least 15 Bcf/d more along the coast. Production revivals in various shale plays. And don’t forget soaring demand for gas-fired power generation. 
In what we consider a misguided move, a Republican State Senator in South Carolina, Shane Massey (the SC Senate Majority Leader), has introduced a bill that would eliminate the use of eminent domain by pipeline companies. The move comes in response to concerns over a 71-mile Kinder Morgan pipeline that will flow Marcellus/Utica molecules to a planned 1,020-megawatt (MW) gas-fired power plant in the state’s Lowcountry, in Colleton County. 
A big announcement from the Trump Department of the Interior (DOI). Yesterday, the DOI announced an immediate pause on all large-scale offshore wind project leases currently under construction in the United States. There are five such projects along the East Coast, including one off the coast of New York State. The DOI said the decision stems from “national security risks” identified by the Department of War in classified reports, specifically concerning radar interference known as “clutter” caused by massive turbine blades. Trump previously negotiated a deal with NY Governor Kathy Hochul to allow two pipeline projects—the Northeast Supply Enhancement (NESE) project and the Constitution Pipeline—in return for building the offshore Empire Wind 1 project (see 
The Ohio Tax Commissioner is facing a lawsuit from Rover Pipeline over an aggressive property tax assessment that inflates the project’s market value. The dispute centers on the state treating $2.2 billion in weather-related construction overruns and an unrealistic “infinite lifespan” assumption as value-adding assets. Critics argue that this approach violates constitutional principles of fair market valuation, under which taxes should reflect what a willing buyer would pay rather than total development costs. 
On July 25, 2025, House Natural Resources Committee Chairman Bruce Westerman (R-AR) and Rep. Jared Golden (D-ME) introduced the Standardizing Permitting and Expediting Economic Development (SPEED) Act to streamline federal environmental reviews for energy and infrastructure projects, addressing delays blamed for hindering U.S. construction (see 
In 2018, Equitrans Midstream, the builder of the 303-mile Mountain Valley Pipeline (MVP), proposed extending the MVP pipeline (after completion) by an additional 75 miles from the current terminus in Pittsylvania County, VA, to Alamance County, NC, to provide natural gas for heating and electric power generation. The 75-mile extension was called MVP Southgate. In December 2023, Equitrans announced it was significantly changing the project, cutting it by more than half and increasing the amount of gas flowing through it (see 
In 2022, then-Massachusetts Attorney General (now Governor) Maura Healey bragged she had “stopped two gas pipelines from coming into this state” and that she opposes new natgas infrastructure in the state.
