Despite serious safety and security issues, the Federal Energy Regulatory Commission (FERC)
issued approval for Spectra Energy's Algonquin Incremental Market (AIM) Project on March 3,
2015. Spectra’s project includes the installation of a massive 42-inch diameter high-pressure
pipeline 105 feet from vital structures at the Indian Point nuclear facility, in a seismic
zone. Unless something is done, construction could start soon.
Although this location of the pipeline poses a dire threat to the 17 million people who live in the
area and NYC, this critical issue has not been adequately addressed in the press. Most people are
unaware of the project, the unacceptable risks to the region and its grave health and safety issues,
as well as the glaring deficiencies in the FERC approval process. Unless New Yorkers and others
with influence know about the potentially catastrophic risks of this unnecessary project, it may
very soon become a reality.
Nuclear expert Paul Blanch and pipeline expert Richard Kuprewicz of Accufacts raised major
concerns about the methodology used to assess failsafe shutdown of Indian Point in the event of
a pipeline rupture. The plant operator, Entergy, conducted a hazards analysis that was accepted
by the Nuclear Regulatory Commission (NRC) and formed the basis for FERC’s approval of the
AIM project’s siting at Indian Point. Mr. Blanch believes this conclusion is based on the
unsubstantiated and unrealistic estimate that the gas valves could be closed in three minutes. The
three minute valve closure estimate from Entergy was accepted by the NRC engineer responsible
for the NRC’s gas line analysis for Indian Point.
Mr. Kuprewicz, on an official call with the Nuclear Regulatory Commission, however,
explained, "in the event of a pipeline rupture in this sensitive location, the system dynamics will
substantially delay the recognition and the appropriate shutoff and responses such that the gas
will explode and burn for quite a period of time." He further stated, “In the event of a rupture of
a sustained duration; it's going to be longer than three minutes given the transient dynamics on
this system."
In a letter to the NRC Chairman and Commissioners on March 17, 2015, in which Mr. Blanch
requests that the NRC rescind its approval to FERC because it was based on inaccurate
information, Mr. Blanch states:
“Some of the more significant deficiencies in the NRC’s analysis of the proposed gas line are:
1. The analysis relies on the EPA ALOHA code to predict the probability and consequences of
fires, overpressure and radiant heat flux. The EPA document states the following:
"ALOHA cannot model gas release from a pipe that has broken in the middle and is leaking
from both broken ends."(Bold emphasis added by EPA)
2. None of the cited references mention 3 minutes for a gas line rupture but do discuss a 1-hour
time to be considered. History and expert opinions demonstrate gas blowdown times range from
30 minutes to many hours.
3. Using more realistic gas release of one to two orders of magnitude greater, the blast radius
would encompass the city water tank and possibly tanks used for core cooling. The NRC/Entergy
analysis stated the switchyard and the diesel oil storage tanks are within the blast radius. Loss of
the switchyard and the oil tanks would result in a station blackout (SBO) and the loss of the city
water tank would render the Unit 2 SBO diesel inoperable due to loss of SBO diesel generator
4. The city water tank serves to supply back-up water to the Auxiliary Feedwater System used
to cool the core during loss of AC power/SBO event.
5. The NRC stated in its analysis that the probability of an explosion after a pipe rupture is 5%
yet this number is not contained in any of the cited references. Research shows almost 100% of
pipe ruptures result in ignition.
6. The NRC analysis assumes that a total pipe rupture will occur in 1% of the pipeline
accidents whereas the references clearly state this occurs in 20% of the accidents.
7. The NRC analysis states: “If this release is due to the underground pipe, the frequency of
explosion will be further reduced by at least an order of magnitude.” (Emphasis added) There is
no documentation or reference supporting this non-conservative assumption.
8. The analysis for the COLA permit for Turkey Point nuclear plants Units 6 and 7 in
Homestead Florida predict a damage radius of more than 3000 feet from a smaller line gas
operation at a lower pressure. The NRC/Entergy analysis predicts a damage radius of 1155 feet
for the proposed Spectra AIM pipeline in Cortlandt, NY, more than double in capacity operating
at a higher pressure.
9. The cited reference “ Handbook of Chemical Hazard Analysis Procedures ” is apparently
dated circa 1987 and does not consider subsequent major gas-line explosions such as the San
Bruno, CA, Sissonville WV, Cleburne TX, Carlsbad NM, and the Edison, NJ transmission and
distribution explosions.
10.The NRC calculates the probability of a gas line explosion at 7.5E-7 per year. My calculations
and the invalid use of the EPA ALOHA code clearly show the probability of core damage to be
orders of magnitude greater than predicted by the NRC/Entergy analysis.”
Senators Charles Schumer and Kirsten Gillibrand, Congresswoman Nita Lowey and Attorney
General Schneiderman’s office officially expressed their concern about the enormous risks from
the proposed expansion in letters to the Chairwoman of FERC. Thousands of residents of
Rockland, Westchester and Putnam counties, and local, county, state and federal elected officials
called on involved agencies and FERC to refrain from granting approval until an independent,
transparent and comprehensive health and safety assessment had been conducted that fully
engages all stakeholders in the process.
- There are alarming rates of unintended gas pipeline failures. According to the U.S.
Department of Transportation's Pipelines and Hazardous Materials Safety Administration, there
were 119 incidents in gas transmission pipelines in 2014.
- In 2014 a 2.5 magnitude earthquake occurred just 10 miles from Indian Point which has the
highest risk of earthquake damage of any nuclear power plant in the country. (In spring 2014 the
NRC called for an earthquake evaluation which hasn’t been done).
- In addition to the potential of an accidental rupture near Indian Point, there is a possibility of
an intentional explosion in the pipeline. Indian Point is a known terrorist target.
Since comments on the DEIS by Attorney General Schneiderman's office in September,
Governor Cuomo’s office has remained silent on the matter.
Fifteen elected officials submitted a letter to the Department of Homeland Security (DHS) urging
them to "take prompt proactive measures to reduce the likelihood of this potential disaster by
halting this dangerous and unnecessary project immediately until a comprehensive, independent,
transparent risk assessment is conducted, completed and reviewed."
In response to that letter, the DHS stated that the NRC is the agency responsible for ensuring the
safety and security of commercial nuclear power plants. However, the NRC's review relied on
information provided by the power plant and the pipeline company.
In response to input by public officials and experts, the NRC recently re-evaluated the risk to
Indian Point using a 60 minute timeframe. However, once again they used the ALOHA model
which is not valid for a situation such as this. Again, the NRC
ignored its own guidance and sought out another, prohibited methodology to obtain the desired
Given the NRC’s inadequate assessment of the risk of siting this pipeline next to Indian Point,
several groups in NY and New England will be filing a Request for Rehearing by
FERC. Additionally, our Senators and Congressmembers must demand that FERC and the NRC
withdraw their approval of the AIM project based on the lack of substantive verification of the
failsafe shutdown timeframe. A full, transparent, independent risk assessment must be
undertaken as soon as possible.
The scale of impact of a "Fukushima on the Hudson" on the New York City area and the
economy of the United States makes it beyond comprehension why FERC, Homeland Security,
the NRC - or any government agency - would even consider putting a pipeline next to Indian
