>> the item before us today is a public hearing on the proposed plan the navy and regulatory agencies are here to discuss the plan and answer questions. however given the public comment period has not closed there will be limitations on what questions from the board that they can respond to. i would like to call up laura from the navy to give us an overview of the proposed plan. then the department of public health on monitoring the ship yard and proposed plan. next will be craig cooper. he will offer brief remarks and

final we have ryan from dtsc who will offer brief remarks. alec and ross. i don't know who will be going. they are also here today. ross will be giving remarks on the role of rwqcb. then we will have public comment and questions. public comment will be two minutes long. i want to encourage everyone to fill out a yellow public comment card. you can find them with our clerk up here. so with that said, i think we are ready to begin. thank you. >> hello. i work for the navy. i am the project manager for

parcel e-2, the portion of the ship yard that i am going to talk about today. i will answer clarifying questions about the proposed remedy. ok. the clean up process is where we are today. we are in the public comment period that began september 7th. >> please continue. >> ok. we are in the proposed plan, if you have the slides in front of you, i am on slide 3. the clean up process starts with the preliminary assessment and then the investigation phase for the site and then we

go into the proposed plan public comment period. that is where we are now. september 7-november 21. i am here today to talk on behalf of the navy how the navy is proposing to remediate or clean up parcel e-2. to reiterate i have brought comment cards for the public so they can submit public comments. we do require written comments and they need to be postmarked by the 5th of november. what happens after the comment period, the document will tell what -- how we have decided to remediate the site and we will design it and monitor the site after we are done. but i will go into that a little more. where is parcel e-2?

you will see that it is the southwern part of the shipyard including 48 acres of shoreline and lowland coastal area. ok. the history. e-2 was created between the early 1940's and late 1960's by filling in with various materials including soil, crushed bedrock, saidments, construction debris and trash and waste. i have a series of photos that show the progression of how this land was created. so you will see in this photo, you can see the 1935 shoreline at the top and what is most of now e-2 was bay. it was filled land. if you follow along to 155 it is more filled in. 1965, even more filled in. 1969, you can see all that is

left that is not land is the drainage channel. and 1974 is pretty much how it looks today. it was bay. it was filled in with soil and the middle area you can see the green outline is the landfill boundary. >> you went through quickly what e- is contaminated with. i know there are a number of parcels that had heavy metals and other wastes. can you go over in more detail what is in e-2 in particular and what is not? >> right. pretty much all of the above because it is a landfill. i will go into that farther in a later slide. maybe if i do not answer your questions later, i will come back to that.

i think that it is better that we go on and i address that with a later slide. >> just so you get to that. >> absolutely. slide 11. what do we know about parcel e-2? this is a photo of investigation that we have been doing. we have done a lot of investigations, numerous soil, trenches, you dig into the landfill to see the wastes and debris that we have. we have done groundwater monitoring samples. you can collect water samples from those. we do continual soil sampling because the landfill generates landfill gases like methane. we started in 1988-2008.

decades of work and numerous samples have been collected. like you were asking me before, the types of things that we have seen are -- we have heavy metals. you have some areas -- this is the good one. let me describe the environmental samples a little more. if you see the trenches -- here we go. the little dots with the line through them on here are trenches that were dug to find where the extent of the landfill is. we have other types of samples. we saw a lot of contamination. >> please say what a pcb is. >> they are associated with things like transformers.

you might remember they were in pole mounted transformers. an oily substance, helps things from being overheated. that was a big contaminant in this area. up in here there was lead contamination. we found similar contaminants within the landfill, petroleum, things of that nature. but the hot spots we have found have been along the edges of the landfill.

we have done numerous groundwater samples. it shows that it is relatively clean and we do not have a lot of contamination. i should point out that groundwater flows from the northwest, so the top of that picture down towards the bay. so we did a numerous groundwater samples back in 2007. if there was a lot of contamination, we would have seen it. those samples were nowhere near

the bay. they were way more inland. groundwater is a really good story. we don't see very much coming out of the landfill. does that answer your questions? let's move on to slide 14. you remember those trenches? this is a picture of what we are seeing in the landfill. you can see that it is construction debris, that nature of stuff from the former base of activities. >> if you can talk about what the health and human impacts are. what is the impact of lead on children. if you give us a sense of the

materials that are cleaned up. >> i am not a risk assessor. this might be a question that i would definitely get back to you on later this week. >> my understanding is pcb could cause cancer. >> yes. some of the contaminants we find could cause cancer. that is absolutely right. some target oregons, some target developing fetuses. i have to point out that we have done expensive risk assessment for human health and e. coli logical receptors and our preferred remedy is -- i

shouldn't say more than adequate. very conservative. we are going above and beyond in how conservative we are being to be protective of those . the critters in the bay, the wildlife and future site users. it is going to be a park. there will be people or kids playing on it. so, when we are done cleaning up, we will absolutely be safe for those future site users. the third type of waste, the thing that is probably the most concerning is the industrial waste. paint sludge, solvants. waste oils like petroleum

products and our pcb's that we have so much of. that is not all of the waste. probably most of the waste is construction debris and material that is in the landfill. early clean up actions. i wanted to talk about the early actionings we have taken to clean up the more contaminated areas. in 2007 we cleared up an area where melted metal was thrown on the shore line over 8,000 cubic yards of debris and took away that risk. we started what we call the pcb

hot spot area, digging over 40,000 cubic yards of soil. we got drums out and pcb contaminated material and were actually ongoing project started up again in 2009 where we are digging out an additional 40,000 cubic yards of pcb contaminated material and the soil has some of that lead, copper, other heavy metals that could mostly be contaminants for the ecological receptors. we are digging all of that out up to 15 feet in some areas. and up here, more inland, adjaceant to the landfill, the area we had where batteries were disposed of or got stored there.

you might know lead is oftentimes associated with batteries. we are digging in this area for lead. we also have solveants in this area that we are currently digging out. these are what we call the hot spot areas we are doing early clean up on. i don't want to belabor this. another thing i want to mention is that i told you about the landfill gas we are addressing. we monitor the gas coming off of the landfill monthly. we installed pipes and a collection system. this is a normal thing. all landfills create gas because material is decomposing and methane is created. we do that monthly.

those results are sent to the regulatory agents. >> question about the methane you collect and then test. are the results published publically? >> yes. absolutely. >> what do you do once you tested them? >> we collect samples to make sure that we are not exceeding regulatory levels on the off chance that we have one or two locations where we actually exceed and we vent that gas. having it build up is what is dangerous. we vent it. >> it goes out into the atmosphere. >> yes. i should point out that this is an interim remedy and the final one we will design with more engineering controls. but currently, yes. it is probably only three times per year we have to vent that.

>> can you describe to me what the effects are with human exposeure to methane? >> nobody is really getting exposed to that. the effects are that it could catch fire and is combustible. that is why you do not want it to build up. we are preventing that, absolutely. and those results are published in a quarterly report that is put in the information repository that is open to the public. >> ok. >> so, let's move on. this is just a before picture. you can see a lot of debris along the shoreline. this is the bay out here. we have done a lot of pretty significant clean up along the edge of the shoreline.

evidence of remedial alternative. they looked at a host of alternatives from doing absolutely nothing to leaving the landfill in place to everything. in the end we landed on a hybrid approach that includes containment of the landfill we have gotten a head start on a lot of the hot spots. we should point out that the navy is required to follow federal criteria. you should know that one and two, they are go and no-go. we are protective or we aren't. we are in compliance or we

don't go. first off we are protective of human health and the environment and compliant with all regulations. -7 are what we call balancing criteria. they just help us get the best balance for whatever our preferred alternative ends up being. and eight and nine is where we are all right now. community acceptance is the public comment period that closes november 1st. the knave serequired to evaluate all of the comments and to look at them in
