responsible for the health and the well-being of the community. so that ends my open remarks. i wanted to just recognize kim atroski, who we will be inviting to speak first. she and her team from the navy. following her will be mos mosin nazimi from the department of toxic substance control, and then, we will heart from the california department of public health, and then followed by the e.p.a., we will also have a presentation from the san francisco department of public health. as you begin to share your statements, please indicate two things: your agency's roles, and the responsibilities in the parcel g work plan. your agency role, and then, your responsibility in the parcel g work plan. all right, kimberly, you're up. come on down. good to see you.

kimberly's bringing with her a team of professionals, derek, zach, thomas, lawrence, and bill. these are an extraordinary team representing the navy. good afternoon and welcome back to san francisco. >> thank you. before i even start the statement that i prepared, i'll start by answering the questions you just asked, who's responsible, parcel g, and the work on hunters point shipyard. the navy is the lead agency. we are responsible for the cleanup of the shipyard. >> president cohen: thank you. >> okay. good afternoon, president cohen and other board members. i'm kim ostrowsky. i have cognizance of all navy bases in the bay area. when we were here last in may, we discussed the circumstances that led to the need to perform a full reevaluation of the

radiological work performed by tetratech at e.c. hunters point. today i'm here to provide you an update, our efforts to assurance residents their safety and our ongoing public outreach activities. we're committed to successfully completing the cleanup work at hunters point and completing property transfer for use by the community. we are also committed to ensuring the public has confidence in the results by working transparently and providing facts based on sound radiological science. in june, the navy released its proposed work plan for retesting of parcel g, which was identified by the city at its top priority parcel for reveemt.

resampling parcel g will allow us to see of ongoing work, or perform additional cleanup. we believe we have a path forward and will be releasing a draft final work plan shortly. the final work plan will be comprehensive and provide new, reliable data for soil and buildings as parcel g, work with include excavations, boring, and scanning of soil and buildings. the navy brac program office will oversee the process and conduct field inspections. further, the navy has hired a third party quality assurance contractor to conduct regular field inspections to ensure the parcel g work is performed properly. all radiological data will be submitted to the radiological fares support office for review.

these physicians were the first to uncover the misreporting by tetratech and will continue their work. the navy will use a comprehensive parcel g work plan as the model for future work plans for parcels b, c, d-2, e, uc-1, uc-2, and uc-3. these work plans will provide for comprehensive investigations and required remediation if necessary. we look forward to starting field work in parcel g once the final work plan is complete. we are grateful to our regulatory partners and stakeholders for their constructive participation in the work plan development and to congress woman pelosi for her support in securing additional funding for fiscal year 2019. since our last discussion, the navy has also supported the california department of public health in its efforts to

complete a health and safety scan of parcel a. 90% of scanning activities across parcel a-1, totaling 56 acres, have been completed. the information collected continues to confirm that the area was not used for work involving radiological materials. the scan did not find any soil contamination or evidence of radiological activities. most importantly, the scan's extremely detailed and sensitive methodology reinforced the fact that parcel a is safe to live and work on. one historic object which was identified as a deck marker was discovered and removed by the navy. the deck marker was found approximately 10 inches below the soil surface at the bottom of the hill on the north side of parcel a-1 in an inaccessible area behind a fence. once removed, no radiological signature remained in the soil arrest area. while we cannot speculate how it came to be in that location, i can tell you that there were no

historic disposal sites on parcel a, therefore it was likely incidentally lost or discarded. i understand that many committee members are not familiar with deck markers. deck markers are low level radiological objects which were used in the 1950's and 60's to support military operations. they were used to light the decks of ships and were also clipped to service members aapparently to indicate each other's position as night the. the san francisco department of hubl health engaged a third party radiological expert to review the deck marker. they concluded that the risk due to radiation exposure from the buried deck marker represented the low end of back radiation experienced by the public. they are less than radiation from a denial x-ray or a trans-continental flight. the parcel a scan did not find any other deck markers or radiological items. again, the scan did not find any

soil contamination or radiological activities. these results are reinforced by the fact that the instrumentation was so sensitive that it was able to identify naturally occurring materials such as potassium in wood chips and fertilizer. this should provide renewed confidence that parcel a is safe. in order to provide a similar confidence in other parcels transferred to the city, the navy will also be completing a health and safety scan of all accessible areas of parcel g after the retesting work is complete and prior to transfer to the city of san francisco. similarly, the navy will perform health and safe scans of the surfaces of parcels d-2, uc-1 and uc-2 to provide confidence in their suitability for reuse by the city. throughout this process, the

navy has undertaken enhanced community outreach to ensure interested community members have access to factual, educational information about the parcel g work plan, parcel a scanning, and the path forward for hunters point. we have attended meetings hosted by other community organizations, including participation in several of the may may yoez's citizen's advisory committee meeting, and conducted regular bus tours of the site. we also have an extensive e-mail and newsletter mailing list. together, these are each over 12,000 people in the local zip codes. in addition, we have office hours for community members to meet with dr. kathrin higly, head of the science and nuclear engineering at oregon state

university. we invite -- for straightforward explanation of our work and our findings. we are thankful for the continued engagement of the board of supervisors and mayor breed, as well as the work of our regulatory partners and congressional representatives to advance the next phase of a comprehensive retesting of hunters point. now i'd like to ask our technical experts, zach edwards, who is a heal and brock roberts, i'll have them join me at the podium, and thank you very much. >> president cohen: thank you very much. i have a few questions in approximate your presentation. i believe you briefly touch odd it. what's the role -- what are the

next steps for your agency in relation to the work plan in the monitoring process? what are the next steps? >> so we released the draft work plan in june of this year, and it went out for a 60 day review. agencies dr dr tthe regulatory s and public had a chance to comment on the workplace. we have drafted responses to the comments, and we will be incorporating thoos into the next version of the work plan, which is the draft version, which will be released by the end of this month. that goes to the regulatory agencies. they have 30 days to accept it. once they accept, it it becomes final, and. >> president cohen: and for those people that are watching at home and not in the chamber and probably don't understand the process, why is it important for you to take and receive comments for the work plan?

>> it's a very public process, and we are interested in getting feedback from the regulatory agencies, from the public. sometimes there can be a different opinion -- a scientific opinion, and we can work through these differences with the agencies when we need to. and then, we can move forward with what we think is the best approach when we finalize the work plan. >> president cohen: and what kind of comments are people submitting? >> we've received a bunch of comments. i'll let derek, who's a little bit more knowledgeable about the work plan -- he can. >> hello. derek roberts -- i think what you are question was what types of comments. i can give you general comments cope co . >> president cohen: that's exactly what i'm looking for. >> it's the extent of soil sampling that we'll be doing, the scanning, the locations. >> president cohen: so are the comments coming from every day people, people that live near the property, people that are

around, watching the process from across the country, are they biologists, are they connected to the process through the science, as well? i would imagine it's a broad sp spectrum. >> they don't always identify where they're from. i can tell you that the regulatory agencies have all submitted comments, and these are u.s. environmental protection agency, department of toxic substances and control, the department of public health, and -- and the city of san francisco department of public health. so california department of public health and san francisco department of public health. >> specifically i want to go back to you, and your presentation. you mentioned the surface scan process. how in depth will the scan go, and does the surface scan include scanning buildings? i think you said you picked up the deck marker.

it was 10 inches below -- >> below the ground surface. so we'll have to put a plan in place what that scanning is going to look like, but our intention, and we haven't drafted that yet. we've just now made the decision and thought it would be prudent to do a surface scan. so we'll put a plan together on what that scan will look like, but our intention is to any accessible areas that we can scan, that that's what we intend to do. >> president cohen: will you be scanning buildings? >> we'll have to evaluate. we likely will not be scanning the building sidewalls, but we can evacuate whether or not we'll be scanning the building floor. >> president cohen: and what materials can the scanner pass through? >> i'm going to let the physicist talk about that. >> i'm zach edwards from the

navy's biological -- >> president cohen: what can the scanner pass through? >> the scanner can pass through any material. that's pretty much the type of radiation we're going to be looking for. >> president cohen: okay just wanted to make sure it would pick up no matter what we'll be scanning. >> the gamma rays, yes, it will be. i'll start with the nuklar regulatory commission, all these dosed are measured in r.e.m.

it will allow a licensed worker to receive up to 5,000 milliram in a year. a member of the general public can receive 100 milliram peryear without being monitored. this deck marker found at parcel a represents an additional 5 milliram for a resident who would stand on that deck marker 24 hours a day, 365 days a year. to put that in context, i received over 5 milliram just flying back and forth to attend this meeting, so it is an extraordinarily low risk, low dose. >> president cohen: one other question for clarification. are there any areas in the surrounding community that could have been impacted by the contaminated matter found at the hunters point shipyard?

>> we start our process by doing historical radiological assessment, and we've reviewed over 15,000 references. of those references, they include interviews, reports, documentation, pretty much any literature that we could get our hands on back as far as our records go, and we have no indication of anything that's happened outside of the shipyard proper. further, we have processes in place such as restrictions on access, we have documentation on all the material that was removed from the site, we have dust control measures in place. there's just -- there should not be any impact outside the shipyard. >> president cohen: okay. if you don't mind, i'm going to pivot to mr. robinson. i have questions about communication. come on down, mr. robinson. so what is the format for the

public meetings to ensure that the community has their questions answered? >> we have several different types of community public meetings that we are involved with. i think the hunters point community, bayview community is -- has a great deal of different types of people, and so that's what we also focus our communication -- we focus on different types of communication -- different types of ways to talk to them. so-so the navy holds at least three community meetings peryear, and those are typically poster board style meetings. in addition, we have bus tours. we also go to local community events where they're already -- people are gathering. we have -- we have different types of forums there, so some of those are more of your town hall-style where we answer questions to people who are asking questions. for example, the city's c.a.c.

meeting, which we attended in september and plan on attending in november , as well. so there's lots of different ways that we communicate with the public. >> president cohen: okay. thank you. who does the community go to for updates once the work plan is underway? >> well, they can absolutely come to me. that is my primary responsibility is working with the community. we -- if they like, we have an e-mail distribution list that we -- anybody who signs up for that, we send them communication. they can go onto our website as well as there's future community meetings planned in the next -- well, every month for the next three or four months. >> president cohen: and i assume there's going to be regularly scheduled community meetings to share information as the work plan -- >> yes, absolutely. already in the plans. >> president cohen: all right. all right. thank you very much. since i have all three of you, this is a moment for

self-reflection, and in hindsight, what could have been done better to prevent oversight like this from happening, over meaning the deck marker? >> yeah, absolutely, and that's a question that we've asked ourselves, and we've already put in place several different measures to accentuate our already very robust this type of work. so in addition to the navy going out regularly, myself, as well as my project managers, we have a third party that we've hired, a company to oversee all of our radiological work. i know that there's been increased oversight from the environmental protection agency, and they plan on taking samples after we've collected work in parcel g. and california department of public health will also be collecting samples afterwards to ensure that everything that we find is of -- you know, without

question. >> president cohen: thank you. madam chair, i don't have any other questions for the navy. i don't know if any other committee people do. >> supervisor tang: thank you, president cohen. any other questions, comments? we don't have any other questions. >> president cohen: fair enough. we will go to representatives from dtsc. mr. najimi is the director of dtsc, and i think you've got your site mitigation and restoration chief program, janet, close by? >> yes. good afternoon, president supervisor malia cohen, president katey tang, and supervisor jane kim. i apologize for my voice, i am under the weather. i am in charge of the site

mitigation restoration program and responsible for overseeing remediation and contaminated sites in the state of california, and with me today is miss janet nito, my program chief from our berkeley office here. thank you for the opportunity to provide some comments. our mission is to protect the public health and environment in california, and i would like to assure you that we take this responsibility very seriously. i also want to assure you that hunters point is one of the top priorities at dtsc, and we have devoted significant resources to the cleanup of hunters point site. dtsc understands the concern that the community and supervisors have of the results of the radiological testing performed by tetratech of the site. let me assure you, dtsc has the same concerns, and we have

provided specific meetings with the navy and have been engaged in several discussions with regulatory agencies and the navy to provide further retesting by the navy of hunters point. dtsc appreciates and supports department of public health's retesting of parcel a to ensure that residents are not exposed to radiological -- [inaudible] >> -- and the surrounding communities are protected from any potential ad versarial impacts. as a result, dtsc and the california department of health and other regulatory agencies

have devoted a significance amount of resources to ensure that public health is protected, and i would like to thank them for all their efforts. just as a point of clarification in response to your earlier question about the roles of agencies, the u.s. department of navy is the lead agency responsible for the cleanup of this super fund site referred to as hunters point. the usepa region nine is the federal agency overseeing the cleanup activities at hunters point to ensure the cleanup is conducted consistent with federal law. dtsc is the lead state agency overseeing the cleanup at hunters point. our role is to ensure the cleanup complies with applicable state laws in a way that is protective of the public health and environment. we also work in collaboration with the california department of public health who's the state authority on radiological matters and is under contract with dtsc in our over sight role

as the state lead agency for the cleanup of hunters point, however california of department health is the lead agency in scanning of parcel a. so the issues of concern are dtsc experts have been working closely with region nine and california department of public health experts as well as the department of navy to review the integrity of the testing done as this site. we're aware of tetratech falsification of the data. inform are that reason and due to additional concerns about data quality, dtsc has recommended that all the data collected by tetratech e.c. be retested. dtsc along with e.p.a. region nine, california department of public health recommended that parcel g as well as other parcels tested by tetratech need

to be retested in these areas. to that end, dtsc along with usepa and california department of public health as well as san francisco city department of public health have all provided detailed comments on the draft parcel g workplace that navy released in june of this year. dtsc recommended that the navy use a different and more comprehensive retesting of parcel g that provides a greater level of confidence in the results. last week, the navy released the responses to the regulatory agency's comments and indicated that the navy agrees to revise the parcel g workplace to incorporate the approach and methods of retesting proposed by dtsc and other regulatory agencies. the navy also stated that it is committed to sample every trench and work space unit. the navy is preparing a revised parcel g work plan that will be incorporating our comments for this retesting and will release

the revised board plan towards the latter part of the this month. dtsc and california department of public health are committed to work have the retesting begin as expeditiously as possible, however the timing of completion of the cleanup will depend on the results of retesting and to what extent, if any, further remediation may be required. in addition, as i mentioned earlier, dtsc along with uspepa region nan and california department of public health wants to ensure the public currently working at hunters point shipyard in parcel a. therefore, we are in constant communication with the california department of public health to be apprised of their results of the scanning of parcel a. dtsc appreciates their efforts in scanning of parcel a, and depending on the final results of their final scanning, dtsc

will work closely with usepa region nine and california department of health and u.s. navy and san francisco department of public health to determine what other remediation or retesting is neededtor parcel a, we understand the supervisors and community members have legitimate questions and concerns about the safety of the hunters point use site. we also understand the need to complete the cleanup at hunters point and allow the development of san francisco's much needed housing. dtsc's primary responsibility and focus is the protection of the community and the environment to ensure the site is safe for present and future residents and workers, we will work with usepa region nine and california department of public health, city of san francisco and the navy to make sure the resampling of parcel g and other areas previously tested by tetratech e.c. is performed

properly, is technically sound, and is completed in a timely manner. finally, dtsc is committed to protect the health of the community at hunters point, and will work with the california department of public health, usepa region nine and others to ensure that concerns about parcel a are addressed expeditiously and all other parcels at hunters point will be safe for future uses of the property prior to transfer to the city. thank you again for your invitation and the opportunity to provide comments at your committee meeting. >> president cohen: thank you for your thoughtful comments. just a few questions. what are the next steps for your agency in relation to the work plan and monitoring process? >> so as i mentioned, we had provide detailed comments that last week the navy responded to our comments and indicated that they will incorporate them into a revised work plan.

navy just indicated that they will release that revised work plan by the end of this month and provide another 30 days for agency's and other's review to make sure our comments are incorporated into the work plan. once we are satisfied that they have been, then, the work plan will become final, and we will have the state oversight role to make sure that the navy will follow that work plan and performs the standards that are identified in that document. >> preside >> president cohen: how will you be involved in the oversight of the data collection process and the analysis? >> the lead for responsible -- responsibility for cleanup has been by the department of navy. what dtsc has done is as the state oversight agency, we have reviewed the work that they have done and made sure that what they have done in terms of

sampling and testing meets the state standards that are required as part of the cleanup for this site. [please stand by]

>> if you recall at the previous hearings they found some dis crem seediscrepancies and raiseo the contractor to the data of the tetr otech. >> president cohen: who is the new contractor now? >> i believe it's better for the navy to respond to that. >> president cohen: i'll come back to them. i have a few more questions.

are there other areas in the surrounding communities tha that could have been impacted by the contaminated matter? the deck mark. they will explain that. that was the only thing that they found at parcel a. parcel g is an area that is secure and the rest of the hunters point as well. that those will be it will determine whether or not contaminations left in those areas and then they have to be remediated before the area is curbed in for protection. >> president cohen: based on what i'm hearing, you are saying the scan is only -- i shouldn't say only. the scan is 95% complete.

it's out scanning 5% that needs to be scanned. that there is no contamination around the -- i'm not just talking -- my question, is not just for the shipyard but other areas uareas up on west point. other people that are fearful, as far as going to third street and even when you cross third street, there's a large number of fear. so what i would like to do, i think i heard it and i wanted to put a finer point on it is people are safe. the deck mark was obtained and there isn't a reason for people to be nervous about living on the shipyard and living in and around the shipyard. >> yeah, i would defer to the

department of public-health to explain what the risk is associated with the marker. as you heard the navy explaining that. >> president cohen: what is the role of the toxic substance control? why are you here then? >> so, we are the state oversight agency. we use california department of public-health. they are the experts for radio logical matters, not the t.f.c. they are under contract to us. for the review of all the rest of the hunters point site, we will collaborate very closely with california department of public-health to make sure that all the remaining areas are compliance with radio logical exposures so there is no harm associated with exposure to the community surrounding the site. but as far as parcel a, california department of public-health took the lead to rescan and determine whether or not there is any remaining

contamination left in parcel a. parcel a, as you recall, was release inside 2004 and has been developed since 2012. we are not oversight role anymore from parcel a, but, if the scanning results from california department of public-health shows that there is contamination left at this parcel, then both the dtfc and ucepa will have to decide what additional testing or mediation needs to be done. at that point, we will become the oversight agency. >> president cohen: as of right now, you are not the lead agency? right? i'm just trying to understand exactly. >> i'm sorry. it's a little complicated. the lead agency for the clean up is the department of navy. >> president cohen: yes, i understand that. i want to know your role. you say you are in collaboration. you are not doing anything.

the other agencies are doing the analysis. what is your role? >> so our role is we have expertise in chemical contamination. >> president cohen: this area of expertise, how does it help with the -- with the over all clean up of the shipyard? >> so, hunters point was not only contaminated with radio logical matters. it has contamination of all kinds of different chemicals. dtsc experts looked over the clean up of all other contaminations and then only with restrict to radiological matters, we relied on california department of public-health. >> president cohen: thank you, that clarifies. >> sorry. i didn't understand your question. i thought you were still focusing on radiological. >> president cohen: there are many things that are associated with the contamination of the shipyard. radio logical, which is the

focal point. your agency, that you represent, is responsible for other chemicals, for lack of a better way to describe it? >> i apologize again. clarify. the navy is the lead agency responsible for clean up of all contamination. chemical, radiological, everything else. our department as a state oversight, has expertise on chemical waste. we oversee all the work that the navy does in terms of cleaning up chemical waste. we use our contractor, california department of public-health, to oversee the radiological clean up of the site. so we do have oversight for all the clean up, except our department doesn't have the expertise on radiological.

>> president cohen: i understand. what is it that you will review with the department of public-health? >> with respect to parcel g or a? >> president cohen: parcel a. >> parcel a is only being evaluated by california department of public-health. >> president cohen: as it relates -- i don't know what that means. a cheerleader? >> we think it's a go ahead approach because there were concerns expressed by the residents and by going back and retesting it, it will provide information to either prove or disprove that there was contamination left. >> president cohen: parcel g? >> parcel g is a complete retesting of all the areas that tetratech conducted sampling. our role is to make sure that the retesting is conducted, consistent with the work plan that is now being revised and released at the end of the month.

>> president cohen: and so, what will you be reviewing with public-health? >> so the department of public-health will be our agent for addressing the radio nucli and they could be being split samples along with the navy so that they can they can analyze the analysis is done properly. we've also considered and recommended having a third party oversight that the navy apparently going to bring on board to have another contractor oversee the work of their contractor to make sure they're also following up. our role is to make sure what they have indicated in the work plan will be done. for example, if they said they would be testing all the soil in the trenching in this area, my staff will be out there,

california public-health staff will be out there and usepa will be out there, to make sure they were taking samples from the areas they were supposed to. >> president cohen: will your staff be doing any testing on the chemical waste? or is it just an oversight, making sure that collection of the samples are done? >> if there is new discoveries that there's additional chemical contamination that hasn't been already addressed, yes, it will be doing that? at this point, the chemical contamination was addressed. >> president cohen: my final question is, what are the next steps for your agency in relation to the work plan and the monitoring process? >> what are the next steps for you. >> after it's released we'll comment back to the navy whether it has incorporated all of our comments in the work plan or not. if it has, we will be giving the groner light to go forward with

the testing to ensure that there is no further contamination left. >> president cohen: how many comments have you submitted so far to the draft form? >> we submitted -- i don't remember exactly the number of pages. we had ttsc's comments on the cover and a memo from california department of public-health attached to our comment ler. i think it was in the 20 to 30 pages long. >> president cohen: are you in agreement with that, janet? >> ok. >> president cohen: thank you. i hope you feel better. i appreciate your answering the questions. >> thank you very much. >> president cohen: the next speaker from the california department of public-health. mark star. the deputy director for environmental health. he has, on his team, anthony chew, his chief, the division of radiation safety and environmental management and also dale sureknack, who does public affairs. good to see you. >> thank you so much, president cohen for in invited us here

today and we're happy to give you an update on our parcel a and we can answer the questions. i'll be begin with closure and i spend my time on parcel a and find preliminary and the up-to-date numbers from the work we're doing there. our department has a role in overseeing the safe use of materials in california in general and this includes medical uses and such as diagnostic x-rays, ct scans, training the staff that handle those, things like that. there's cancer treatment and many areas we oversee but also industrial uses, research uses and and others.

it's a important component of our department public-health protection programs. you just heard from mr. nazimi, because of the skills set and expertise, they contract with the department. because they're the lead agency reviewing d.o.d. clean up activities for the state. and we are able to provide the expertise for the radio logic aspects of the activities at military sites for transfer to civilian use. >> you asked our role. our department is in this capacity that dtsc contracts for and we're both consultative and regulatory. we do review of the radiologic clean up work. we look at the plans for clean up. the work plans as you've just been discussing for parcel g, we're part of the process of commenting on the work plans. we'll analyze the survey data as it's the processes underway. we occasionally do confirm tory

surveys and our own sampling. split samples. our lab in richmond does that work. we also review the conditions, if there's a limited release, we review the conditions of the release of the property. and we license entries. it's including workers at the sites. our purpose with the contractors is to oversee worker safety as well as public-health and safety and the work that they do. specifically for parcel. i won't repeat those. you know them better than i do. but because of our expertise, as we've discussed, we've identified for the request to do a health and safety scan of parcel a one based on the concerns raised by residents and

others about information at hunters point in general. we have experience with other health and safety surveys and we will fulfill the need for an independent entity to conduct such a survey. we will undertake the survey and the navy is funding the project. so specifically, our work lan for parcel a-1 focuses on three critical areas. the first one is to detector assess the possibility of any radiation from something in the soil. it could still be there or may have been introduced at some point. the radiation survey is what we're doing and it's the most appropriate approach for a health and safety survey like. this health and beta radiation don't penetrate soil. the outdoor areas that are uncover ground has been our primary focus or those that have limited cover. there's landscaping, there's sidewalks, there's asphalt, things like that. they are more likely to have

detectable substances than areas with a thick foundation and gravel. we have focused on those areas to date. because we're more likely to find something there and those soils are generally representative of the site as a whole. lastly, our concern is the safety of the residents. this is based on the potential that there could be exposure to residents and so we're assessing that site for gamma radiation using a scan to see if there's direct exposure to humans and the environment beyond normal background levels. the way our work plan works, is when the radiation measurement higher than background is found, the location is documented and investigated by conducting supplemental measurements. we use two other instruments held over the spot for 30 minutes or more and we determine what that radiation is and what the isotope is that is buried there and whether it's naturally occurring. we confirmed that elevated

levels, any confirmed elevated levels that are not natural materials result in notification of all the involved agencies that you've heard from. >> president cohen: let's back up. it involves notification to all the involved agencies. what about the notification to the community offer to your government partners? me? >> that's coming up. >> president cohen: got it. >> so we coordinate on a response action. as i'll get to, the deck marker is a good example of that particular process. but first, i want to mention since our scan began on july 16th. we used two devices, one that is over a large, flat area. we also have used walk-over surveys for areas that we can't access with a vehicle. we're just about -- we completed the part, the analysis is almost done and as you heard earlier, we're close to 95% done with the walk-over survey.

we've just added the construction areas. and so that adds a little bit more time. we expect to be done this week. so we have work with the homeowners association and you asked about notifications and based on resident requests, we have expanded our original work plan. we scanned outdoor private areas between residential units. we've scanned the slopes going down from the residential areas, which is fill-up material that is uncover. it's useful to scan that. we did the large soil pile at the southwestern edge of the parcel. to date, all of these have been completed. we'll be offering windowsill dust testing as well to residents. so far we have 87 natural occurring anomalies. 42 of those were from the walk-over survey and 45 from the tow to ray.

that's brand new information we'll put in our weekly update for the residents. we initiated the work-plan protocol and identified all 87 of those as being potassium 40, a natural-occurring isotope and it's been around us since the solar system is formed and it's in our bodies. in addition, we detected one naval radio containing deck marker as you've heard about on september 7ing, the location was the bottom of the hill and in an undeveloped area you heard the navy contractor removed that is when something is a man made substance we would bring in the other agencies and the contractor. we opened the process. the object was about 10 inches of soil and the hole was scanned

in order to demonstrate that there was no other contamination around it in the soil, the marker and removed. specifically, about that, we're asked to provide a little information on the findings of that specific marker and the hazards. the surface level removal of the marker. it's about 1/15th of that amount in an hour. it's about 1/15th of what someone would get if a single dental x-ray. someone would have had to sit on the spot for 15 hours just to get radiation equipment to one dental x-ray. anybody more than a meter away

from the spot would not have received any exposure above background. so getting to your question, it took me a while. to keep residents we provide. we don't have all the data analyzed so the final report will be available in late fall. but we, every step of the way, understand the residents desire to be informed of our scanning and what we are up to and have had questions related to radiation and to that end, we have let several homeowners and we began on july 5th. we wanted to prioritize this for the residents and they're our primary concern. we also, most recently, had one on september 19th. which was about the deck marker and explaining what it was, what we found, what it means

comparisons to the radiation that we all get every day around us. that is how we have been communicating with residents. we also have a website where all the documents are posted and the progress reports. we have an e-mail that we accept questions and respond to and we continue to accept and respond input throughout so we adjust our work plan based on that input as we've already done. we will be doing so as we start scanning parcel a2 in a short while. lastly, i just want to say is we continue to coordinate with all the involved agencies, including your own san francisco department of public-health and office of community investment and infrastructure, as well as the state and federal partners that you will be hearing from here today. >> president cohen: thank you, mr. star. i appreciate your presentation. your presentation was mostly focused on parcel a-1.

i was wondering, i would like to hear your plans for parcel g. >> we'll be hearing from e.p.a., the three mond tory agencies. i coordinated on our comments that you just heard, we were part of that and we're expecting and the navy has agreed to incorporate those comments in the work plan and we will see the revised work plan at end of the month. our role, you know, these are two quite different situations as i'm sure you have gathered, parcel a was release aid long time ago and people are living there. what we're doing is health and safety scan, which we have done in other areas in order to see if there could be something there that could potentially expos residents. at the rest of d.o.d. sites and hunters point, we look at the work plan and the data and after

the work plan is underway. we will do some of our own surveys if necessary. to really important. that people have been receptive to and opened to receive your feedback. specifically, i'd like you to take a couple minutes to talk to us about how does radio activity really work? now, please, don't go into a full-on 40-minute lecture but maybe you can just give us a primary level of how radio activity works? >> how did you know, i had a power point right here. so, it's cosmic rays, you've

heard about airline flights and being exposed. those are cosmic rays. there's a number of natural isotopes, po tas see yum 40 and there's a lot of natural radioactive substances that people could potentially be exposed to in certain situations. and the concern is that it can be gamma rays or x-rays and any of those cases, ionid and for humans it means damage to d.n.a. or other important molecules in our body and mutations or cancer can result as one of the most common concerns with radiation.

>> president cohen: thank you. i don't have any questions. i'll turn to my colleagues to see if they have any questions. doesn't look like there are. i appreciate your presentation. next we will hear from the e.p.a. the environmental protection agency. i think we have enrique, john, kelly, maria. welcome back. >> good afternoon, president cohen, supervisors, thank you for this opportunity to present to your meeting here today. i am the director of the addition of the u.s. environmental protections agencies regional office here in san francisco. i'm joined here by my colleague- >> please continue. >> sure. >> i'm joined here by john chestnut, and lilly lee, the remedial project manager for the hunters point site.

the public's concerns are important to us. we take them seriously. as such, this site remains a high priority to b.p.a. region nine. we have assembled a team of national experts on radiological clean up to advise us and provide technical expertise. all this in fulfillment of our over site role. that is our role here is to oversee the work that the navy is conducting. you have already heard from the navy. the lead on the clean up at the hunters point site. e.p.a. and the state of california have been overseeing the navy's radiological work to ensure the safety of the surrounding communities for the past decade. long-term radiological monitoring by various parties of groundwater, ground surfaces have shown no exceedance of third party contractors routinely conduct in-person

observations of the current radiological clean up work. in response to the discoveries about the data, e.p.a. is part of the clean up team with the state and the navy has been actively involved in the development of the new work plans of the uncertainty of the site and reassure the residents of their safety. we have stepped up tour over site activities at the site as well and planned to have staff on site during the plan retesting. we will take samples to ensure the integrity of the data and restore public confidence in the clean up. with regard to parcel a, with the recent discovery of the naval deck marker at parcel a and the issues we've discussed with you, regarding the work on the shipyard, we are aware of the keep concern that you and the community have had about any

potential impacts of the shipyard on the current and future residents and workers. e.p.a. was on site when the deck marker was unearthed, observed it's removal and analyzed the data collected to ensure that the public was not exposed to harmful levels of radiation from this object. e.p.a. has carefully studied the health effects and we do not believe it would have posed a health risk if it was left in place. radiation readings during and after removal indicated no residual contamination in the soil. >> president cohen: thank you. >> we appreciate the work of our colleagues at cdpa, department of public-health and their cannes that discovered this all the work they have finished across parcel a1 does not show radiological exposure to the public. when they finish the work they have already started, the california department of toxic substance control, and the navy

will have value waited the results and discuss any follow-up scanning or testing efforts and the city and parcel a residents. as we have stated before, the concerns we have would not impact the health of the current rear dents in parcel ar. the areas under question are enclosed under protective covers or inside locked buildings and secured parts of the. for the other parts of the site outside of parcel a, due to drew to the concerns, epm and the navy grow that comprehensive testing is before any new parcel transfers proceed. the navy must clean up the area until it is safe enough to transfer. e.p.a., the navy and the r
