JULY 21st MEETING: A final vote did not take place on July 21st as anticipated. Instead Efren Carrillo sided with Kerns and Kelley in giving Dutra more time to amend their proposal. Carrillo stated that his opposition to the project has not necessarily changed but he is willing to give Dutra more time. Zane and Brown remain opposed to the project. Final vote has yet to be scheduled.

JUNE 9th BOS VOTE: The County Board of Supervisors took another straw vote on June 9th and decided 3-2 against the plant. Supervisors Valerie Brown and Efren Carrillo joined Shirlee Zane in voting against the plant. Both Brown and Carrillo had made their initial "yes" votes contigent on more info and with that they have changed their votes. The final vote will take place on July 21st. Supervisor Zane cites main issues as "hav[ing] to change the general plan, the noise ordinances, the urban growth boundary and go[ing] against the (opposition of the) city of Petaluma" With 144 conditions, the county does not have the staff to monitor it. For more info on June 9th vote: Channel 7 News Report, Petaluma360.

MAY 30th JARED HUFFMAN MEETING: The event was very well attended (over 400 people), overflowing the room at the Veterans building. It was hosted by Assemblymember Jared Huffman with US Congresswoman Lynn Woolsey, and State Senator Mark Leno attending. The County Board of Supervisors were advised by their legal counsel not to attend and didn't.

Recurring issues were:

Air quality concerns, which were elaborated on by Dr. Brian Moench of Utah Physicians for a Healthy Environment who represented Moms for Clean Air in the third panel. (see video below)

Threat to wildlife - The distance this plant would be from the rookery is not adequate. Also, evaluation of endangered marsh harvest mouse was done in winter when the mouse is not very active. Another evaluation should be done in spring/summer.

Barging aggregate, which Dutra says will cut down significantly on greenhouse emissions, is now being called into question. They won't be able to begin barging for 4-5 years and possibly never because Marin may not allow them to barge the aggregate out of San Rafael. This raises questions about what the additional trucks will mean to our city in terms of air quality, congestion, noise, etc. According the EIR they would be already be using 750 truck round/trips per day at peak times WITH barging. How many more without?? Update: Dutra cannot barge aggregate and will be sourcing it from Shamrock Materials next door. How will Shamrock get the additional aggregate?

EIR - There are still a number of outstanding concerns about the EIR including that it underestimates emissions by basing calculations on averages not peak production. Also, asphalt is not a rainy weather product so the numbers are further skewed by the fact that the volume will not be produced over twelve months but more like nine. Also, regulations aren't taking into account cumulative emissions and impact on our air quality.

Economy - Dutra plays up the jobs but the plant will only create ten jobs. There is plenty of permitted capacity at existing plants to meet demand for asphalt in Marin/Sonoma. Also, the economic impact needs to be evaluated from BOTH sides. Millions have been spent on restoring Shollenberger and surrounding wetlands. This area draws a significant number of tourists to our city. They may not come to stare and two 70 foot silos and breathe questionable air. Businesses who have located in the nearby business park to look at Shollenberger may not stay.

Friends of Shollenberger have posted some video clips on YouTube.

MAY 21st PLANNING COMMISSION VOTE: The County Planning Commission voted (3-2) to allow Dutra to exceed the noise limits set in the Sonoma County General Plan at Haystack Landing. Dutra is unable to mitigate the noise to comply with the general plan so there are concerns that it will be disruptive to the birdlife in Shollenberger Park, not mention a nuisance to people enjoying the park. Other factors related to the General Plan like visual impact were not considered.

No Petaluma Asphalt Plant
  • A thorough evaluation of this plant's impact on our local economy has not been considered. The plant could be disruptive to residents and hurt local businesses which could, in turn, hurt Petaluma's economy.

  • Dutra is "greenwashing" this issue, trying to make an environmentally unfriendly project appear eco-friendly. They place much emphasis on their barging plans to cut down on greenhouse gases but it is now in question as to how soon, if ever, they will barge aggregate to the Petaluma site. (Source: KFTY TV50 News, May 28)

  • Dutra's prior plant in Petaluma was shut down by the Bay Area Air Quality Management District (BAAQMD) for operating without a permit and failing to meet Best Available Control Technology (BACT). Since 2000 they received various notices of violations from BAAQMD. (Source: "Wrong place for an asphalt plant", Argus, February 12)

  • Dutra has had a poor track record in Marin County where the local community has spent that last 20 years battling with them over noise, operation hours, and various other violations. (Source: Marin Grand Jury Report)

  • This plant is on County land, which means no tax dollars for Petaluma and no local oversight.

  • The Environmental Impact Report for this new “state-of-the-art” facility still leaves many concerns over noise, air quality, etc.

  • Children are especially susceptible to hazardous air pollutants, which can lead to cancer, respiratory illnesses and other diseases.  (Source: Cal EPA OEHHA) This plant will be located less than 2 miles from 22 Petaluma schools and within 3 miles of 42 schools!

  • The plant could drive away wildlife in Shollenberger Park, ruining a rare wildlife area that the city has spent over a decade restoring.

  • This plant will be the first thing people see as they enter our town with two 62 ’ silos!

Cost of Dutra Asphalt Plant for Petaluma

GET THE FACTS! not half truths


The Proposed Asphalt Plant

  • The County Supervisors is expected to approve Dutra's plan to build an asphalt producing and recycling plant at Haystack Landing, at the southern end of Petaluma.

  • Dutra already owns the land and runs a rock quarry on it. It is just outside Petaluma City Limits so the county gets to decide for Petaluma. The proposed asphalt plant will be less than a mile from the Mc Near Landing and Riverview housing developments. The new plant will be at the entrance to Petaluma, within a couple hundred feet and across the river from Shollenberger Park and the Sheraton and all of those businesses in that area.

Getting to Know Dutra

ZONING: Dutra purchased the San Rafael Rock Quarry (SRRQ) in 1986 but in 1988 they expressed "'shock' at having recently learned of the property's RMCP (Residential Multiple Planned Commercial) zoning and indicated Dutra's desire to 'immediately take the necessary actions to request a zoning change to a mining use'. At least aware then that they RMCP zoning meant it could not expand its operations, Dutra nonetheless failed to initiate any action to rezone the property back to M-2 (Heavy Industrial). (Source: Marin Grand Jury Report, pg. 8)

UNAPPROVED SITE IMPROVEMENTS: In 1995 seven new office buildings, totaling over 15,000 square feet, and extensive new site improvements were first discovered at the SRRQ. There are no records of any building permits, grading permits, septic permits or planning approvals for these improvements. (Source: Marin Grand Jury Report, p 10)

EXPANSION VIOLATION: "A July 11, 1996, 'violation letter' from Bay Area Quality Management District referred to multi-million dollar quarry expansion, which was done without required permits. This expansion reportedly increased significantly the quarry operating capacity. (Source: Marin Grand Jury Report, p 10)

  • Dutra Dredging fined $735,000 for ocean discharge violations between 1999 and 2003, according to the EPA. "The EPA alleged 30 instances of disposing more than 86,000 cubic yards of dredged material outside the specified disposal site; 108 instances of barges seriously leaking during transit - including in sanctuary waters - totaling more than 115,000 cubic yards; and one instance of a Dutra vessel traveling directly through an environmentally sensitive area near the Farallon Islands." Dutra claimed "the violations alleged occurred from incidental leakage." And, apparently the inability to properly steer a barge. (Source: Marin IJ 8/17/2006)

  • Dutra illegally dredges five-acre area of Biscayne Bay, Florida. “This is the largest unauthorized sea-grass-destruction case ever investigated by DERM (Miami-Dade's Department of Environmental Resources) ,” declares Grossenbacher, chief of DERM's coastal resources section. “At the very least there was gross negligence.” (Source: Miami New Times, 9/7/2000)

Shollenberger Park

  • Shollenberger Park is jewel of Petaluma and one of the last wetlands of its kind in the country. The plant could drive away the birds, pollute the air and water, and ruin the wetlands.

  • Shollenberger Park is enjoyed by 150,000 visitors annually and is an outdoor classroom and wildlife research location. A few years ago Shollenberger Park was ranked one of the top 4 new birding sites in the country by Audubon Society.  It now attracts 195 species of birds.

  • The City of Petaluma has spent well over $1M on trails and park restoration.

  • The EIR’s analysis of noise fails to evaluate in any meaningful way the severe impacts of loud noises on the existing egret/heron colony. (Source: Comments of Petaluma River Council on Dutra Asphalt FEIR)

  • Experts comment on negative Wildlife Impacts of Asphalt Plant. (Source:

Health Risk

  • The smoke from the plant and the diesel trucks moving the asphalt are the top two cancer causing pollutants. (Source: Alan Pendley)

  • Asphalt plant operations are associated with the release of polycyclic aromatic hydrocarbons (PAH’s), respirable particulate matter, volatile organic compounds such as benzene and formaldehyde. These air pollutants can lead to diseases such as cancer, leukemia and respiratory problems such as asthma and bronchitis.

  • The EIR also underestimates the release of hazardous air pollutants by underestimating maximum hours of operation. The EIR’s calculations assume a maximum of ten hours of operation each day.  However, the Project description makes clear that the Project may operate up to 12 or more hours each day. This error underestimates all Project emissions by 20% or more.  (Source: Comments on Dutra FEIR pg.2)

  • Children are especially susceptible to hazardous air pollutants, which can lead to cancer, respiratory illnesses and other diseases.  (Source: Cal EPA OEHHA) This plant will be located less than 2 miles from 22 and within three miles of 42 Petaluma schools.

  • Ten percent of the facility’s annual production would consist of rubberized asphalt. (Source: Draft EIR)

Not Right for Petaluma & Sonoma County

  • The Petaluma City Council is opposed to the plant and has written a letter stating their position.

  • The Cities of Sebastopol, Santa Rosa, Cloverdale and Healdsburg have all sent letters to the County Board of Supervisors expressing their objection to the project. They cite concern over the BOS's lack of respect for Petaluma's city unanimous opposition to a project with the city's urban growth boundary. (Source: Letter from Sebastopol, Press Democrat)

  • The noise, fugitive emissions, and visual blight of the asphalt plant could hurt local businesses and drive down housing values.

Myth#1: Dutra is simply moving their exiting Petaluma plant down the street.

This is not the same plant. The previous Dutra asphalt plant in Petaluma was shut down on November 1, 2007 with violations. Dutra's new asphalt plant in Petaluma will be capable of processing 665,000 tons of material. (Source: Comments on Dutra FEIR pg. 5) The old plant produced a five-year historic average of 131,498 tons/year of asphalt. (Source: Comments on Dutra FEIR pg. 19) The revised proposal had reduced peak production from 400 tons to 300 tons per hour but maintains the same over annual level or production. (Source: Comments on Revised Proposal p.3) The new asphalt plant will use approximately 125 barge trips per year year to deliver raw materials from their San Rafael quarry. Dutra's old asphalt plant were under permit to operate just 15 roundtrip barge trips in 2004. (Update: Barging will not happen to Dutra's site as they will be sourcing aggregate from Shamrock Materials) Dutra's new asphalt plant is expected to run from 174 to 750 (at peak) truck roundtrips/day. (However, the EIR air quality section is only based on the lower number.) (Source: Comments of Dutra FEIR pg. 3) The new plant will also feature two 62 foot asphalt silos that will greet everyone as the enter Petaluma! (Source: Dutra)

Myth#2: Dutra’s new state-of-the-art plant makes it completely safe for people and the environment.

Former Petaluma Council Member, David Keller’s, first hand experience to another state-of-the-art facility was not encouraging. Fugitive emissions and lax management by Dutra are real concerns. A facility that is not fully enclosed still has room for fugitive emissions if not operated or maintained properly. There is also concern from uncovered trucks taking asphalt away from the facility as well as cumulative diesel emissions from tug boats and trucks (now a concern at the Shamrock facility that will be supplying Dutra with the aggregate - how will Shamrock supply the aggregate without increasing their volume?). They were not on top of "leakage" with their dredging business and took the liberty to expand their Marin operation without proper approvals. According to the EIR, "The proposed project would also result in significant and unavoidable cumulative impacts related to: aesthetics, air quality, water quality, land use, and noise." (Source: Dutra Draft EIR)

Myth#3: The noise from this plant will be totally contained.

The EIR states the noise levels to sensitive receptors using Shollenberger are unacceptable and cannot be mitigated. The county needs to amend the noise element of the Sonoma County general plan to allow for the plant.

Myth#4: Dutra owns the land at Haystack Landing so they can do what they want with it.

This area is not currently zoned for Dutra’s intended use.  They purchased the land under those circumstances.  The county will need to rezone the area from heavy commercial to industrial, and amend the county general plan to allow the project.   Haystack Landing is also within Petaluma's urban growth boundary but unanimous opposition by Petaluma’s City Council, including Mayor Torliatt, did not sway the Board of Supervisors when they took the straw vote.

Myth#5: Dutra will only be operating during the day.

They have only said they “intend” to operate during the day except for emergency projects at which time they will be able to operate 24x7. According to the San Pedro Coalition Dutra said they would not operate 24x7 in Marin but have been running 24x7x365 for years. They will be able to operate 24x7 for state and municipal projects, which is 80% of their business. If they are legally able to operate 24x7 and have the business to support it then why wouldn't they?

Myth#6 This will be good for our economy and will create many jobs.

This plant will provide about 10 jobs locally. “the project would not result in longterm employment growth in the area.” (Source: Dutra Environmental Impact Report, Vol. 1, V.I. General Impact Pg. 1) The tax revenue from the plant will go to the county not to the City of Petaluma. A property value study indicated home loss values of up to 56% due to the presence of an asphalt plant nearby. (Source: Blue Ridge Environmental Defense League) And, nearby businesses are protesting this plant. If this plant discourages businesses from locating in the nearby business park it will be a loss to Petaluma in both tax dollars and jobs.

Myth#7 Dutra has been operating for years in Petaluma without any complaints.

According to Bay Area Air Quality Management District records Dutra's Petaluma asphalt plant was shut down November 1, 2007 for operating without a permit and they failed to meet Best Available Control Technology (BACT). They also received a number of violations and complaints, including "burnt rubber" and "gray smoke". (Source: "Wrong place for an asphalt plant", Argus, February 12, BAAQMD Records, Moms for Clean Air)

Myth#8 We need a new asphalt plant in southern Sonoma County.

The EIR states, "There are three existing asphalt plants in Sonoma and Marin counties... based on these locations, it appears the region's needs would still be met for asphalt production and recycling without the proposed project: (Source: Dutra Environmental Impact Report, Vol. 1, V.I. General Impact Pg. 2)

Myth#9 This plant will reduce traffic on Hwy 101.

Clarification!! This plant will worsen the traffic situation on southbound 101 leaving Petaluma. “The project would add trips to congested segments of southbound Highway 101 during the AM peak hour, which is a potentially significant impact. The project could potentially add traffic to northbound Highway 101 during the PM peak hour where traffic has been observed to break down which is also a potentially significant impact. The project would add traffic to the congested southbound ramps during the AM peak hour where operation would be LOS F without project traffic. This is a potentially significant impact. Overall the project has a significant impact on highway operations.” (Source: Dutra Environmental Impact Report, Vol. 1, V.J. Transportation/Traffic Pg. 28) The mitigations Dutra references on their website are to reduce traffic congestion caused by their trucks exiting their facility onto Petaluma Blvd. not the slow traffic caused by so many asphalt trucks on Hwy 101! Their mitigation does not indicate they will be reducing the number of trucks that will need to get on/off Hwy 101 to deliver asphalt. Update: The concern over truck traffic is now shared with Shamrock materials since Dutra cannot barge the aggregate into their facility then the question remains how Shamrock will get the additional aggregate Dutra needs without signficantly increasing demand for trucks at their facility.

Myth#10 This plant will help Petaluma pave its roads.

Wait a minute! Dutra had a plant here during the time Petaluma became "Pothole Capital of California". How exactly is this new plant going to help us in a way the old one didn't?!

Myth#11 The people opposed to this plant are just hysterical and misinformed.

The opposition to this plant is not misinformed it is MORE INFORMED. The opposition to this plant is a diverse group of people including our Petaluma City Council, Moms for Clean Air, the Petaluma Mothers' Club, local business people, and The Friends of Shollenberger. The concerns are many and certainly include protection of Shollenberger Park. However, even if there were no park you would still be left with air/water quality concerns, disruption to nearby businesses and residents, the potential loss of local tax dollars, and the industrial aesthetics of the project. Much effort has been spent trying to discredit the opposition in order to discourage people from becoming educated on this issue.

VIDEOS: Petaluma City Council Meeting - Monday, January 25th:

David Keller, Former Petaluma City Council Member - First-hand visit with Dutra to a "state-of-the-art" plant in Southern California. It yielded caustic smells, wasn't covering trucks leaving the facility, and the "totally-enclosed" air tunnel used to diminish fumes was not working. An example of failed "state-of-the-art" technology and lack of oversight.

Alan Pendley, Consulting Chemist - Impact of carcinogens on the environment and our health. Asphalt fumes and diesel fumes are some of the most carcinogenic out there! Dutra will pump 20,000 gallons of Petaluma river water onto gravel that will become asphalt. That is mostly salt water. When you put the salt on gravel it will keep the asphalt from lasting as long. If they use fresh water it will come out of Petaluma's already limited allotment. If you locate it at Haystack Landing it must be contained to be safe for the community. It will not only affect the park but the Sheraton, housing areas, and businesses in the area.

Bob Dyer, Senior Docent, Shollenberger Park - Noise from Dutra's proposed asphalt plant poses a threat to the resident heron/egret colony (colony 121). This colony of great egrets, snowy egrets, and great blue herons are the subject of research by Dr. John Kelly of the Cypress Grove Research Center at Audubon Canyon Ranch. The birds are a protected from disturbance during breeding season by federal law under the Migratory Bird Treaty Act. Dutra's proposal that an artificial colony be set up for the birds is not supported by Dr. Kelly, an expert in the field.

Joe Caramucci, founding member of Point San Pedro Road Coalition - Representing a community suffering from Dutra Plant in their community in San Rafael. Dutra has been a very bad corporate citizen there and the plant has had a negative impact on the community. They have been battling with Dutra for decades.

Joan Cooper, Friends of Shollenberger Park & Clean Air - Petaluma against the Dutra plant in its current form and in it currently proposed location. Council is going against the sustainable attitudes of the electorate.


Comments by Petaluma River Council on Revised Dutra Proposal - March 12, 2010

Dutra Project violates the federal Clean Air Act - " The Dutra Project violates the federal Clean Air Act (“CAA”) because it fails to incorporate Best Available Control Technology (“BACT”) to reduce greenhouse gas emissions. Sections 165(a)(4)( and 169(3) of the CAA require BACT to limit emissions of the greenhouse gas pollutant, carbon dioxide (“CO2”) for any project that will have a potential to emit more than 100 tons per year of CO2. (See, In re: Deseret Power Electric Cooperative, PSD Permit No. PSD-OU-0002-04.00, PSD Appeal No. 07-03) (Exhibit A) The DEIR concludes that the Dutra Project will generate more than 8060 tons per year of CO2 (DEIR, p. V.B.-38) – which is 80 times higher than the 100 ton per year BACT threshold set by the Clean Air Act. Therefore, BACT is required. The DEIR is inadequate because it fails to disclose this requirement, and fails to propose implementation of BACT."

Comments of Petaluma River Council on Dutra Asphalt General Plan Amendments - "The proposed “Area Policy” allowing this Project to exceed the General Plan’s specific and mandatory noise limitations is arbitrary and unlawful. Under the plain text of the newly adopted General Plan, moreover, the Project is located within the Petaluma/Novato Community Separator, and thus cannot be approved without the concurrence of the County’s voters. Finally, the General Plan precludes redesignation of the Project site for Limited Industrial uses." (April 15, 2009)

Sonoma County Planning Commission Staff Report on General Plan Amendment - "Recommendation: Staff recommends that the Planning Commission hold a public hearing on the proposed special area policy and recommend that the Board of Supervisors approve the General Plan Text Amendment." This would allow Dutra's asphalt plant in Petaluma to exceed the noise limits set by the recently approved Sonoma County General Plan.


Board of Supervisors Draft Conditions of Approval - "Proposed Project Description: This proposal is for a Use Permit and Design Review Permit for an asphalt batch plant with a maximum production capacity of 225,000 tons per year, an aggregate and sand distribution facility with a maximum annual capacity of 289,175 tons and a recycling operation with an annual maximum capacity of 150,000 tons resulting in a facility with a total capacity of 664,175 tons per
year with inclusion of asphaltic oils and crumb rubber. The project also involves the construction and operation of barge off-loading facilities on the Petaluma River for sand and aggregates and a conveyor system to bring the materials to the facility.

Comments on Dutra Final Environmental Impact Report (FEIR) - "Unfortunately, the FEIR fails to resolve the significant deficiencies raised in the Council’s prior comment letter and the other comments submitted on the Project (Dutra's proposed asphalt plant at Haystack Landing in Petaluma). The FEIR remains woefully inadequate. As a result of the failure to incorporate feasible mitigation measures and alternatives in violation of the California Environmental Quality Act (“CEQA”) the Project will result in significant environmental impacts on the Petaluma river, animal and fish populations, air quality, water quality, and noise, among other impacts. The Council therefore requests that the County prepare and circulate a Supplemental Draft Environmental Impact Report (“SEIR”) to address the issues raised in this and other comments, and to require implementation of feasible mitigations and alternatives required by law." pg 2/239

Dutra Final Environmental Impact Report (FEIR)

Comments of Petaluma River Council on Dutra Asphalt FEIR - Letter to Sonoma County Board of Supervisors detailing inadequacies of FEIR.

Dutra Draft Environment Impact Report (EIR) - "Based on the analysis contained in this Draft EIR, implementation of the proposed project would result in significant unavoidable project-specific impacts related to: aesthetics (scenic vistas, visual character), air quality (operational emissions and inconsistency with the Clean Air Plan), land use (conflict with applicable plans, land use incompatibility), traffic (access for neighboring residential land uses) and noise (from barge unloading facility, asphalt plant, recycling facility and operation of all equipment simultaneously). The proposed project would also result in significant and unavoidable cumulative impacts related to: aesthetics, air quality, water quality, land use, and noise."


A recession breathes life: Less smog equals more toddlers - "WHEN glam rockers T-Rex released the song “Children of the Revolution” in 1972, the revolution they had in mind was not America’s Clean Air Act. But two economists later calculated that about 1,300 extra one-year-old Americans were trying to stand up and walk at the end of that year. These babes survived because the 1970 law led them (and their mothers) to breathe in fewer sooty particles than they otherwise would have.

Wrong Plant, Wrong Place - Response by Friends of Shollenberger to Dutra's claims about their proposed asphalt plant in Petaluma RE: health hazards, Dutra's history, road traffic, visual blight, wildlife degradation, and jobs.

City of Sebastopol Letter to County Board of Supervisors - In reference to the Dutra Petaluma Asphalt Plant: "The City of Sebastopol is concerned that the County of Sonoma would ignore the unanimous vote of a City Council and its community and make a major land use decision contrary to that City's own determination, as evidenced not only by its immediate vote but also by its historical citizen vote adopting an urban growth boundary. Secondly, we are concerned that the County would force changes to its General Plan to accommodate this particular land use"

Dutra Petaluma's Violations & Complaints - During the time Dutra operated an asphalt plant in Petaluma they had a number of violations and complaints. They were shut down in November of 2007.

Dutra Dredging Fined $735,000 - "The company will pay a $450,000 EPA fine and pay NOAA $285,000 to fund projects to protect and restore the natural environment of the Gulf of the Farallones National Marine Sanctuary, where some of the dredge material ended up."

Asphalt Plant Pollution - Blue Ridge Environmental Defense League (BREDL), an organization that has been leading a Clean Air Campaign to reduce toxic pollution from asphalt plants in North Carolina.

Petaluma City Council Letter to the Sonoma Board of Supervisors - Expresses concern over the projects impact on Shollenberger, local residents, the visual impact to the city, and river navigation. Opposes project but if approved requests additional mitigations.

Petaluma City Council Meeting Summary - Summary of the January 26th Petaluma City Council Meeting by Joan Cooper, Friends of the Shollenberger Park & Clean Air

Marin Grand Jury Report Regarding Dutra Facility - Multi-million dollar expansion done without permits, noise complaints, pollution, late hours of operation, "illegal intensification of the non-conforming use". Dutra does not have the history of a good neighbor.

Friends of Petaluma River Letter to Planning Commission - Letter opposing the current location of the planned asphalt plant at Haystack Landing.


Dutra Project Moves Forward - October 13, 2010, Argus Courier - " Sonoma County Supervisors Mike Kerns, Paul Kelley and Efren Carrillo decided Tuesday that San Rafael’s Dutra Group can build and operate an asphalt plant at Haystack Landing, a decision sure to have consequences in the near future. Kerns and Kelley are not standing for re-election in November and Carrillo was clearly uneasy playing the role of decision maker for the board."

Dutra hearing now set for Oct. 12 - August 19, 2010 - "The county’s Permit and Resource Management Department still needs to release a summary report on Dutra’s proposal and allow time for public review of the document. Work on the summary has been held up because the consultant doing the environmental work for the county went out of business and the work was transferred to another firm."

County hearing on Dutra asphalt plant postponed again - March 11, 2010, Argus Courier - "A hearing on the issue by the county's Board of Supervisors scheduled for March 16 will have to be pushed back because Shamrock Materials, which Dutra plans to share a barge-offloading site with, has not submitted information needed for the proposal to be addressed. "

Not in my bird sanctuary, you don't.... - February 20, 2010, Daily Kos - " Nothing in me can reconcile the desire to put an asphalt plant into a natural wetlands, thus devastating dozens upon dozens of species of indigenous plants and animals, causing perhaps another million dollars in gross pollution fines as a chronic offender, to blight not only on my town but on any town where they would take their "business."

Time to end Dutra's magic show - February 4, 2010, Argus Courier - "Dutra was not truthful with the U.S. Coast Guard and Sonoma County, saying that their barges and tugs would be moored outside the Petaluma River’s federally-dredged navigational channel. Dutra doctored its official maps so that their barges and tugs appear to avoid interfering with current and future commercial and recreational river traffic. The Coast Guard called them out on this fabrication, stating that the remaining channel clearance around a moored barge is not safe."

Dutra submits revised plan for asphalt plant - February 4, 2010,

High time for county to reject Dutra project - January 26, 2010, Press Democrat - " Shollenberger Park in Petaluma is a park, not an industrial site. This city park is a rich and productive historic wetland area restored to support wetland species and to filter impaired water going to San Francisco Bay. It serves a dual purpose of providing an area for dredged river sediments."

Poll: Strong Opposition to Asphalt Plant - December 11, 2009, Argus Courier - "More than 85 percent of respondents said the plant should be denied, while 13.4 percent said it should be approved."

Petaluma wetlands is a birder's dream - June 9, 2009, Petaluma360 - "Visits from regional and national birders could enliven the local economy, creating jobs as well as producing sales and tax revenues, for birding is one of the most popular hobbies in this country. A 2001 study by the U.S. Fish and Wildlife Service produced amazing numbers. There are 46 million birders who travel to locations like the Petaluma wetlands, annually. They create $32 billion in retail sales, 13 billion in federal and state taxes, and are responsible for over 800,000 jobs! Even the small town of Arcata, Calif., draws 150,000 visitors a year for its 150 acres of wetlands."

Asphalt plant appears headed for defeat - June 10, 2009 - Final action delayed until July; supervisors cite health, other concerns in change of stance - The Press Democrat, June 10th "Dutra Material's controversial plan to erect an asphalt plant across the Petaluma River from Shollenberger Park appears doomed to eventual defeat after three Sonoma County supervisors declared Tuesday evening they would not support construction of the facility.

Asphalt plant proposal draws greater scrutiny; State, federal representatives say it will take more than supervisors’ OK to get Dutra plant on line - Argus-Courier, June 4, 2009- "The countywide brawl over the siting of a new asphalt plant has escalated to a much higher political level."
