River Herring and other fish getting 'nuked'


On March 8th JRWA filed a legal challenge against Entergy's operations at Pilgrim Nuclear Plant.  One of the significant issues at hand is the number of fish that get sucked into the plant's cooling system.  Those of us who follow the annual Jones River herring run are well aware of how imperiled river herring are in the Jones and beyond.  River herring are the third most impinged (sucked into the grates) species at Pilgrim.  In fact, based on Pilgrim's monitoring data, river herring have been impinged at Pilgrim every year from 1980 to 2010.  The total number of river herring impinged in this time period was estimated at 92,001 (68,489 alewife + 23,512 blueback herring).  Peak impingement years included:

  • 1995 when alewife alone was the greatest single species impinged at the plant and total river herring impinged was 41,128 individuals (39,884 alewife + 1,244 blueback herring)
  • 2010 when alewives were the second most impinged species (after Atlantic silversides) at an extrapolated total of 12,680 fish plus an additional 271 blueback herring. This is more than three times greater than the total number of fish estimated for the entire 2010 Jones River river herring population.

Herring and the Herring Alliance need our help.

Greg Wells of the Herring Alliance was kind enough to come down to our annual meeting and give a great talk about the history, status, and future of river herring.  Those of you who attended know how urgent the need is to protect these fish.  You also saw the massive task that the Herring Alliance has in front of it in order to affect positive change.  This is the big scale stuff that our small organization can't handle on it's own.  So we rely on them to do the heavy lifting and they rely on us to back them up.  Greg sent us an email today asking for some of that back up.  I can't improve much on his wording so I'll just let his note speak for itself. You should feel free to contact them or us if you want more information or just to talk it over.  We will be following up as an organization, but support from individuals is also key.

Hi Pine and Alex,

Thought I’d send you an quick update on our herring efforts and let you know about the open comment period and hearings scheduled on Amendment 5 to the Atlantic Herring FMP.  Comments on the proposed management options are being accepting now through April 9, and seven public hearings are coming up, including one near you on March 27th. Final decisions on management measures – including protections for river herring – will be made in June.

Leading up to these final decisions, there are a number of ways JRWA and your members can help ensure adequate protections for river herring are voted through and ultimately approved for implementation (hearing attendance/testimony, sign-on letter, op-eds in local papers, encouraging elected officials to weigh in on the process, etc.). I’ll keep you posted as these opportunities come up. In the meantime, please help us spread the word about the upcoming hearings (link below). It would be really great to have you or others in your community at a hearing to let Council members know that groups like yours are putting in a lot of time and effort to restore river herring runs, that we need them to support these efforts by establishing protections for these fish in federal waters. I can provide you some talking points, and if you or anyone is interested I’d be happy to meet up before the main event.
  
Thanks,
Greg

JRWA Letter to NOAA: Re: Endangered Species Act, Section 7 Consultation

            Re: Endangered Species Act, Section 7 Consultation:
            U.S. Nuclear Regulatory Commission, Pilgrim Nuclear Power Station, Plymouth, Massachusetts: Relicensing

Dear Ms. Colligan:

We are writing about the Section 7 consultation by the National Marine Fisheries Service (NMFS) for the Pilgrim Nuclear Power Station (PNPS) in Plymouth, Massachusetts.  This consultation is required under the Endangered Species Act (ESA), 16 U.S.C.S. §§ 1536 et seq.  As you may know, the U.S. Nuclear Regulatory Commission (NRC) is conducting re-licensing proceedings on PNPS’s operating license.  The license expires on June 8, 2012 and the licensee, Entergy Nuclear Operations, Inc. (Entergy) seeks permission to continue operating for another 20 years.  See, Pilgrim LR Proceeding, 50-293-LR, 06-848-02-LR, NRC Docket No. 50-293.   Since it began operation in December, 1972, PNPS has been using once-through cooling water from Cape Cod Bay and discharging pollutants to the Bay.

Our research appears to show that the NMFS has yet to concur with the NRC’s July 2007 “biological assessment” under the ESA, nor has NMFS issued its own biological opinion or otherwise concluded an informal consultation. The last relevant communication in the relicensing proceeding record is a January 23, 2007 letter from NMFS stating ‘[c]omments relative to the Section 7 Endangered Species Act consultation will be provided by NMFS Protected Resources Division under separate cover.” NUREG-1437, Supp. 29, page E-45. [1] We have been unable to locate a NMFS concurrence letter or any subsequent comments from NMFS on the NRC biological assessment for PNPS. 
      2

                                                                                                                                                     
If NMFS has yet to make its decision on whether to concur with the NRC’s biological assessment, we urge the NMFS to withhold concurrence at this time, for the reasons stated below.  If NMFS has concurred, we request that the concurrence letter be placed in the NRC docket as part of the record in NRC’s operating relicensing proceeding.

Relevant Law

The ESA regulations at 50 CFR 402.14(a) provide in pertinent part,
“[e]ach Federal agency shall review its actions at the earliest possible time to determine whether any action may affect listed species or critical habitat. If such a determination is made, formal consultation is required, except as noted in paragraph (b) of this section.” 

The two exceptions in 50 CFR 402.15(b) provide, 

“(1) A Federal agency need not initiate formal consultation if, as a result of the preparation of a biological assessment under § 402.12 or as a result of informal consultation with the Service under § 402.13, the Federal agency determines, with the written concurrence of the Director, that the proposed action is not likely to adversely affect any listed species or critical habitat.”  In this case, the Director is the assistant administrator of NMFS.  50 CFR 402.02.  (emphasis supplied)

The NRC has determined that ten federally listed endangered or threatened species that are under full or partial NMFS jurisdiction “may be affected by continuing operations of PNPS.”  NUREG-1437, p. E-73. The NMFS also informed the NRC that Cape Cod Bay is critical habitat for the Northern right whale. See, NMFS letter to NRC, June 8, 2006, NUREG-1437, p. E-15.  ESA consultation is also required on this critical habitat in its own right as well as on the ten listed species. The NRC has not addressed the critical habitat for Northern right whales in the 2007 biological assessment. 

In its 2007 biological assessment, NRC determined that operation of PNPS for another 20 years “would not have any adverse impact on any threatened or endangered marine aquatic species.” NUREG-1437, p. E-73.  On this conclusion, the NRC is required to initiate a formal consultation, obtain NMFS concurrence on the 2007 biological assessment, or otherwise conclude an informal consultation.

Relevant Facts

PNPS is located on Cape Cod Bay and withdraws up to 510 million gallons per day (mgd) of once through cooling water from the Bay.   Under the federal Clean Water Act and its state
counterpart, PNPS has an NPDES permit.  This permit expired on April 29, 1996, but has been administratively extended by U.S. EPA for 16 years.[2]  The state water quality
       3

certification is also expired.  In addition to NPDES regulated pollutants, liquids containing radioactive wastes are also discharged to Cape Cod Bay under NRC regulations. The NPDES permit allows Entergy to discharge to Cape Cod Bay least 510 mgd of heated condenser cooling water (daily maximum), 255 mgd of thermal backwash (daily maximum), 19.4 mgd of service cooling water (monthly average), .06 mgd of make up water (daily maximum), 4.1 mgd of intake screen wash, and stormwater runoff from at least four storm drains.
                                                                                                                                                    
As described by the Massachusetts Supreme Judicial Court in upholding the state’s authority to regulate the PNPS intake and discharges, “the environmental impact of these systems is staggering.”  Entergy Nuclear Generation Company vs. Department of Environmental Protection, SJC-10732, 2011 Mass. Lexis 163, April 11, 2011. The state’s highest court further stated:

“As the sources referenced by the department indicate, the ecological harms associated with CWISs are well understood. The intake of water by a CWIS at "a single power plant can kill or injure billions of aquatic organisms in a single year." Riverkeeper, Inc. v. United States Envtl. Protection Agency, 475 F.3d 83, 90 (2d Cir. 2007), rev'd in part on other grounds, Entergy Corp. v. Riverkeeper, Inc., 129 S. Ct. 1498, 173 L. Ed. 2d 369 (2009). See Riverkeeper, Inc. v. United States Envtl. Protection Agency, 358 F.3d 174, 181 (2d Cir. 2004).   In light of the SJC’s ruling, a careful ESA consultation is warranted.

In the PNPS relicensing process, Energy prepared an Environmental Report (ER) that the NRC used, along with other information, as the basis for its final environmental impact statement.  NUREG-1437, p. E-53.  The NRC agency staff then produced the 2007 biological assessment based on the final environmental impact statement. 

Entergy has submitted a NPDES renewal application to EPA.  Entergy makes no secret about its position that it should not be required to change its operating methods to reduce its environmental impacts on Cape Cod Bay.[3] The pending NPDES permit renewal process, which Entergy is likely to delay by challenging any efforts to require operational changes to its water use and discharge, should not drive NMFS’s consultation process.  Entergy itself has argued against a delay in a similar nuclear power plant relicensing proceeding.[4] While we are not suggesting that NMFS has delayed its concurrence decision pending EPA action on the NPDES permit and State Water Quality Certification, we are simply pointing out Entergy’s position that NMFS should not delay its decision.

Deficiencies in NRC’s Biological Assessment

It is our view that NMFS concurrence with the NRC’s biological assessment is unwarranted and would be inconsistent with the ESA.  The assessment relies almost entirely upon information produced by Entergy’s consultants and ignores scientifically and commercially available data. 16 U.S.C. 1536(a)(2). The species and habitat data is clearly not sufficient to make an informed decision as to the effects of PNPS’s operations. Bob Marshall Alliance v. Watt, 685 F. Supp. 1514, (D. Mt. 1986), aff’d in part and rev’d in part and rev’d in part on other grounds, 852 F.2d 1223 (9th Cir.) cert. den. 489 U.S. 1066 (1989).[5]  The NRC’s biological assessment ignores readily available data from such organizations as the Whale and Dolphin Conservation Society (WDCS), Provincetown Center for Coastal Studies, and others that would provide specific information about the impacts of PNPS on listed species.
                                                                                                                                                    
Some specific deficiencies in the NRC’s biological assessment are listed below.  This is not a comprehensive list.

First, the biological assessment unlawfully limits the geographical area it covers.  The action area for purposes of the ESA is defined in 50 CFR 402.02 as “all areas to be affected directly or indirectly by the Federal action and not merely the immediate area involved in the action.” The NRC has improperly attempted to limit the scope of its biological assessment to “near PNPS” or “at PNPS.” See e.g., E-66, p. E-67, E-68, E-73.  One reason this is improper is highlighted by comments by the Massachusetts Office of Coastal Zone Management (CZM) on Entergy’s Clean Water Act 316 demonstration report.  Exhibit 1, hereto, June 27, 2000 letter.  CZM has stated that the thermal loading from the PNPS may impact “hundreds of acres of Cape Cod Bay.”  Thus, it is this agency’s position that Entergy’s operations at PNPS affect not just the area “at” or “near” PNPS but “hundreds of acres of Cape Cod Bay”. While CZM’s comments relate to Entergy’s CWA compliance, it is also relevant to the assessment of impacts on listed species and critical habitat in Cape Cod Bay.

CZM stated Entergy’s impingement events may impact “food web dynamics in the region of Cape Cod Bay near the Entergy-Pilgrim station” and “at least one modeling study predicts that hundreds of acres of Cape Cod Bay may increase by one degree Celsius or more due to thermal loading from the discharge….”  It cites “evidence that the rate of fish impinged by the continuous action of the cooling water intake structures is thousands to tens of thousands per year….” The NRC has not addressed how thermal loading, impingement, and entrainment impact the food web, food supply for the listed species and critical habitat.

Second, the biological assessment ignores scientific data readily available about whale activity in the area.  For example, a quick review of available data produced this photo of a federally endangered fin whale (balaenopter physalus) in front of PNPS. The NRC’s biological assessment contains a scant half page of “assessment” of the impacts of PNPS on the fin whale.  NUREG-1437, p. E-71.

Third, NRC’s Biological Assessment as to the effects on sea turtles is contradictory and lacking in specific habitat data.  It relies on stranding data, and on Entergy’s monitoring data. p. E-66.  It states, “The applicant has been monitoring aquatic communities in western Cape Cod Bay since 1969.  No Federally endangered or threatened species have ever been observed in Cape Cod Bay near PNPS, or in the facility intake and discharge areas, during the duration of these studies.”

The reliance on Entergy’s “monitoring” is totally misplaced because Entergy’s monitoring covers only fisheries and plankton – not turtles or whales.  Based upon our preliminary review of the 77 Environmental Monitoring Reports prepared by PNPS in the last forty years, we have found no requirement that the presence of sea turtles or whales be documented or reported.[6]  Therefore, these reports cannot form the basis of a reasonable biological assessment regarding sea turtles.

Further, the NRC’s statement about the absence of listed species near PNPS is at odds with the statement in the EIS at NUREG-1437, page E-65 that a federally endangered loggerhead turtle was stranded .63 miles south of PNPS on Priscilla Beach in 2003. Finally, as NMFS has noted, sea turtles have been impacted by other nuclear power plants on the East Coast.  See, e.g. Nov. 21, 2006 NMFS Biological Opinion for Oyster Creek Nuclear Generating Station.

Fourth, the NRC biological assessment fails to address the fact that river herring are now considered a candidate species under the ESA. 76 Fed. Reg. 67652, 67656 (Nov. 2, 2011).  About two months ago, NMFS announced a 90-day finding for a petition to list
           6

Alewife (Alosa pseudoharengus) and blueback herring (Alosa aestivalis), collectively referred to as river herring, as threatened under the ESA and to designate critical habitat
concurrent with a listing.  76 Fed. Reg. at 67652.   NMFS’s ESA determination on river herring is due by August 5, 2011.[7]

According to the NRC, alewife (Alosa pseudoharengus) “is one of the most commonly impinged species at PNPS (ENSR 2006).  Alewife larvae and juveniles have been collected in the PNPS entrainment sampling.  Juveniles and/or adults have been consistently collected in the PNPS impingement sampling program.  Over the last 25 years (1980 to 2005), alewives have had the third highest number of individuals impinged at PNPS, based on annual extrapolated totals (Normandeau 2006b).” NUREG-1437, p. 2-34. This assessment raises several serious questions.  For example, the NRC states that alewife “spawning occurs in freshwater rivers and streams,” p 2-34, but then says larvae are found in the entrainment sampling at PNPS.   It seems extraordinary that larvae would be entrained at PNPS’s saltwater intake, several miles from suitable freshwater habitat in the area such as Eel River and Jones River.  This raises the question, which has not been assessed, as to whether PNPS thermal discharges are disrupting alewife reproduction.

Entergy’s own records show that during a ten-year period, 1994 to 2004, 46,286 alewife and 16,188 blueback herring were impinged at PNPS, for a total of 62,474 river herring.
These facts stand in stark contrast to the wholly inaccurate predictions on the impact to alewife from PNPS in the mid-1970s.  In 1975, PNPS’s consultant Stone and Webster stated that over the 40 year operation of PNPS (1972 to 2012) impingement and entrainment would result in a loss of 29,410 alewife.[8] Worse yet, this prediction was based on the operation of two nuclear generating units at PNPS – the second one was not built. The impingement numbers for alewife (42,286) and blueback herring (16,188) from 1994 to 2004, a ten year period, were 1.5 times as many alewife impinged as predicted for the full 40 year time period.

In relation to the total Jones River river herring stock, PNPS’s impingement and entrainment numbers are significant.  In 2004 alone, PNPS impinged 2,192 river herring (alewife and blueback herring).  In the following year, 2005, the total estimated Jones River river herring stock was 804 – therefore in 2004, PNPS impinged 2.75 times as many fish as the entire Jones River river herring run the next year (2005).

Fifth, the NRC improperly excluded potential impacts from Entergy’s dredging project
from the biological assessment.  The EIS states, “other activities that may affect marine
aquatic resources in Cape Cod Bay include periodic maintenance dredging….However,
based on discussions with plant personnel, there are no plans for dredging of the intake embayment or discharge canal at PNPS.”  NUREG-1437, p. 4-75. This is inaccurate. In
2012, Entergy is scheduled to dredge the intake channel.   It has permission from the state
to dredge 43,200 cubic yards of in-situ sediments plus a potential 11,000 cubic yards of
over dredge.[9] Entergy requested and received a waiver of the state requirement for an

          Entergy’s Pilgrim nuclear power station on the shores of Cape Cod Bay in Plymouth, Massachusetts may be impacting endangered species like the fin whale, loggerhead turtles, the critical habitat for the endangered Northern right whale, and river herring.  In a letter to National Oceanic and Atmospheric Administration (NOAA), Jones River Watershed Association and Pilgrim Watch say the federal Nuclear Regulatory Commission (NRC) likely violated the federal Endangered Species Act in the relicensing process by ignoring potential impacts to the endangered species and their habitat.  Letter available at: http://www.jonesriver.blogspot.com/

            Entergy, a Louisiana based corporation, has a license to operate the Plymouth nuclear plant but it expires in June 2012.   Entergy has asked the NRC to extend the license for another 20 years.  The groups say Entergy’s license should not be extended until it upgrades the cooling water system that takes water from Cape Cod Bay and discharges harmful pollution, potentially impacting the endangered species and their habitat.

            “Since 1972, Pilgrim has been taking a half billion gallons a day of sea water from Cape Cod Bay, running it through the nuclear reactor system to cool it down, and dumping it back into the Bay.  This water is super heated and polluted.  For decades, Entergy has been sucking in and killing hundreds of thousands of fish and larvae, and millions of fish eggs and plankton every year with this process.  This is an outdated and destructive method and has created a killing zone in Cape Cod Bay,” said Pine duBois of the Jones River Watershed Association in Kingston.  “Local groups, towns, and the state are putting time and money into preserving and restoring our rivers and bays. Entergy is undermining this work with its destructive operating methods.   If Entergy wants to keeping running Pilgrim for another 20 years, it must upgrade the cooling water system to stop this unnecessary destruction of marine life and properly assess endangered species impacts.” she added. 

            "Cape Cod Bay is a national treasure.  It is critical habitat for endangered whales and some of the planet's most endangered turtles migrate through.  This year we've seen unprecedented numbers of dolphins stranded in Cape Cod Bay.  Our laws that protect these species should be rigorously upheld and actions that jeopardize these species should be thoroughly reviewed,” said Mary Lampert of Pilgrim Watch. “This is just one more way that Entergy, with the complicity of the NRC, is evading public scrutiny and federal and state requirements today, and planning to continue to do so over the next 20 years,” she added.

Mussels

Mussels have been on my mind lately.  Those of you who've seen me walking around in a sling this week know why.  But yesterday it was mussels of a different sort that I was thinking about.

A big component of the restoration design is the installation of three riffles. These riffles are critical to the restored channel in several ways.  Most importantly they control the grade of the river as it slopes through the site.  By controlling the grade these riffles ensure that there is adequate water depth for fish to pass even at the lowest typical flows.  They can be thought of as 3 big 'steps' that raise the water through this relatively steep section of the Jones. In this picture you can see the furthest upstream riffle immediately following its construction yesterday (9/29).  The carefully selected and placed stone will ensure that sufficient upstream water depths are maintained and that fish can swim up the channel.

These riffles are a centerpiece of the design and when the project is complete the will contribute to improved habitat for a wide range of aquatic wildlife.  Of course, construction is a disruptive business.  The last thing we want to do is negatively impact wildlife while we are working to protect it.  So early yesterday, as the water levels were adjusted to allow for the riffle install, we went on mussel patrol.  Mussels can move surprisingly fast for a bivalve but sometimes they just can't keep up.  We walked the site where the water had been drawn down and relocated any of the mussels that were ending up high and dry.

Turtle, snail, and fish patrols were part of the process too.  And everything was safely relocated away from the construction activities.  It's been amazing to see how quickly some animals have been to take advantage of the improved channel.

UN-Dam It!

That's been our slogan throughout the project and now it's a reality. If you blinked you missed it. Working around some issues SumCo decided to dig into the dam this morning (9/20). Lack of rebar and breakable concrete made the demo easier than expected and over the course of the day they had the whole thing out. While there is still a lot of work to do to make this a successful restoration, the dam was the symbolic obstacle. And it's gone...
