We know that masks can prevent you from spreading COVID-19 to others, and studies show it also reduces your own risk of contracting transmission of COVID by 65%. The bottom line is that we want to keep our businesses open, protect our economy and our lives. And masks are an effective way to do that. Coloradans are smart mask-wearing is already quite widespread among the general public. But we need to increase the percentage of people wearing masks, and we need to do it right now. This is not just about Coloradans. It's also about making sure that out-of-state visitors = especially those from hot zones like Texas and Arizona and Utah that flocked to Colorado over the Fourth of July weekend = respect our laws and our lives by complying with mask ordinances. Mask wearing is key to Colorado's economic resiliency and recovery Masks are an effective tool for keeping our economy on the right track, inspiring consumers, and protecting our lives. Many professions already require mask-wearing in the workplace. Businesses are required to post signage mandating mask-wearing, and must refuse entry or service to people not wearing masks. Many large national companies currently require mask-wearing in their facilities, including Airlines (Alaska, American, Delta, JetBlue, Southwest, Spirit, United), Apple Store, AT&T, Best Buy, Costco and more. Support from local governments: 40 counties and municipalities in Colorado have already led the way by instituting local mask orders Includes using or waiting to use any form of public transportation, a taxi service, car service, or ride-sharing service. Masks aren'tpolitical Wearing a mask - or not wearing a mask - is not a political statement. COVID-19 doesn't care what political party you belong to. The virus doesn't care what belief system you have. The virus is the virus and it is a threat to every single one of us. #### COVID-19 CDPHE Questions & answers about the COLORADO Department of Public statewide mandatory mask order Health & Environment ABOUT THE EXECUTIVE ORDER What is the statewide mandatory mask order? Executive Order D 2020 138 requires people in Colorado all individuals over ten (10) years old must wear a face covering over their noses and mouths: When entering or moving within any public indoor space. While using or waiting to use public (buses, light-rail) or non-personal (taxis, car services, ride-shares) transportation services. People do not need to wear a mask when they are: Hearing-impaired or otherwise disabled or who are communicating with someone who is hearing impaired or otherwise disabled and where the ability to see the mouth is essential to communication. Seated at a food service establishment. Exercising alone or with others from the individual's household, and a face covering would interfere with the activity. Receiving a personal service where the temporary removal of the face-covering is necessary to perform the service. Entering a business or receiving services and are asked to temporarily remove a face covering for identification purposes. Are actively engaged in a public safety role such as law enforcement, firefighters, or emergency medical personnel. Officiating at a religious service. Giving a speech for broadcast or an audience. When does this executive order go into effect? The mandatory statewide mask order goes into effect at midnight on July 16, 2020, and is in effect for 30 days. The executive order may be extended. What is a public indoor space? For the mask order, public indoor space" means a publicly or privately owned, managed or operated, enclosed indoor area that is accessible to the public, is a place of employment, or is an entity that provides services. Public indoor space does not mean a person's residence, including a room in a motel or hotel or a residential room for students at an educational facility. Public indoor spaces include but are not limited to: Government buildings Nonprofits Transportation People who are 10 years old and younger. People who cannot medically tolerate a face covering. Children ages 2 and under should NOT wear masks or cloth face coverings. What does it mean to be unable to medically tolerate a face covering? Essentially, this means a person who has trouble breathing or anyone who is unconscious, incapacitated, or otherwise unable to remove the cloth face-covering without assistance, according to the Centers for Disease Control and Prevention. Read more from the CDC about other reasons face coverings may not be possible in every situation or for some people. Do I have to wear a mask when I exercise indoors? You do not have to wear a mask if you are exercising alone or with others from your own household. But, if you are exercising with a group of people in a public indoor space, then yes, you must wear a mask. What if I'm swimming in an indoor pool? You should take your mask off while swimming in the pool but you must put it back on while you are not swimming but in the pool area. Do I have to wear a mask outdoors? The executive order does not state that you must wear a mask outdoors unless you are waiting on public or non-personal transportation. However, it is best to wear a mask whenever you cannot keep a safe distance (at least 6 feet) from other people. We encourage you to wear a mask whenever you are in crowded spaces, either indoors or out. Do I have to wear a mask at grocery or hardware stores? Yes, you must wear a mask when entering any kind of store. Do I have to wear a mask at a restaurant? Yes, you must wear a mask when entering or exiting a restaurant. You may take the mask off when you are seated but must put it back on when you stand up to use the restroom or to leave. Does this apply to houses of worship? Yes, this applies to any indoor setting open to members of the public. If there are certain religious spaces where members of the public are not allowed, such as spaces only accessible by clergy, then this does not apply to those limited settings. Individuals officiating a religious service are not required to wear masks but are encouraged to do sO if feasible. MASKS AND LOCAL GOVERNMENTS Can cities and counties opt out of the statewide mask order? What is the difference between a mask and a face covering? Masks and face-coverings are interchangeable terms. Cloth masks or face coverings or disposable masks are acceptable as long as they cover the nose and mouth. People may wear surgical or other, more protective masks, but we encourage people to use cloth face coverings to preserve medical masks for health care and other essential workers. While at work, people should wear masks appropriate to the business in which they work. If we are social distancing, why do we still need to wear masks? It is becoming increasingly evident that masks are an inexpensive and easy way to limit disease spread. Together, masks and distancing offer a greater measure of protection. We strongly encourage all people in Colorado to practice the Big 3: Wear a mask. Wash your hands. Keep your distance. Face coverings are most essential when distancing is difficult. People who are unable to wear a face-covering should take other measures to reduce their risk, including distancing, frequent hand washing, and disinfecting surfaces. Where do I get a mask? You can make or buy your own. You can use a bandana or scarf. CooracowasPoecticom has resources to help you make or buy a mask. The CDC has a video about making your own mask. How should a mask fit? Face coverings should: Fit snugly but comfortably against the side of the face. Be secured with ties or ear loops. Include multiple layers of fabric. Allow for breathing without restriction. Be able to be laundered and machine dried without damage or change to shape. Cover your nose and mouth. Wearing them under your nose or chin is ineffective. How do I clean and sterilize my mask? Wash your cloth mask regularly with your regular laundry. How do I put on and take off the mask? Try not to touch your eyes, nose, or mouth when putting on and taking off your face covering. Hold the mask by the corners and avoid touching the front or back of it. Wash your hands before putting your mask on and right after you remove it. Where can I find out more? The CDC and CDPHE web pages are excellent resources. Can I get carbon dioxide poisoning or lowered oxygen levels from wearing a mask?

BOX 466 SILVERTON, COLORADO 81433 PHONE/FAX 970-387-5766 sanjuancounty@trontier.net July 16, 2020 The Honorable Cory Gardner United States Senate Senate Dirksen Office Building SD-B40B Washington, DC 20510 Dear Senator Gardner: The San Juan County Commissioners would like to express our concerns with the recent decisions by the San Juan National Forest to stop the Durango and Silverton Narrow Gauge Railroad (DSNGRR) from proceeding with fire mitigation and bridge repair. In light of the COVID-19 Pandemic we are all struggling for our economic survival. The DSNGRR is a critical component of our summer tourist economy. Our local businesses are extremely dependent upon the thousands of visitors the train brings to town every day. The Town of Silverton, San Juan County and our Emergency Services are very dependent upon the sales tax revenues generated by the train passengers. It is critical for the well-being of our entire community that the DSNGRR be allowed to continue their fire mitigation and bridge repair operations as soon as possible. Given the extreme economic hardships that the COVID-19 virus has created, it is vital that we all work together to keep our economy moving. Now is not the time for lawsuits and stop work orders. Any assistance that you can provide to getting this matter resolved in a timely manner would be greatly appreciated. Sincerely, 1 -A B C. MMEk Peter C.

In recent weeks, the U.S. Forest Service has ordered the D&SNG to stop two projects along its tracks. On May 27, thel Forest Service sent the railroad a cease-and-desist order after concerns were: raised the D&SNG was removing and selling mass amounts of trees durangoheraldcom/ma/omdinghtmierotfwctu-aRue.MIMOEMI2Rlemh22o,AAkQ029125aGaGVALAMEMTQNSIBY along its right ofv way to reduce fire: risk.

"Special Agent Leach must currently focus on investigating this trespass action, making him unavailable to work at this time on his rebuttal to defendant's cause and origin expert reports," " Licht wrote. Harper said D&SNG crews never. left the railroad's right of way. He said he was told: it could take two months to complete the investigation. "That's almost the whole summer," he said. "They are now financiallyi impacting our entire operation." The Durango & Silverton Narrow Gauge Railroad's fire mitigation project has raised concerns it is cutting down large and old trees, and selling thet timber to a logging company. Courtesy of. John Harper Around the same time, the D&SNG learned a rainstorm had washed out about 40 feet oft track at the Elk Creek Bridge, about 5 miles below Silverton, which could take upt to four months to repair. Harper said the D&SNG had crews ready to begin work on the bridge when the Forest Service asked the railroad to stop. James Simino, the Forest Service's Columbine district ranger, wrote in a July 2 email that the D&SNG "is allowed to take emergency action necessary to protect life and property, but (D&SNG) is still required to seek authorization at the earliest opportunity." Simino asked for a detailed plan of repairs to the bridge and track, assuring the D&SNG it would be reviewed immediately. The D&SNG has not submitted plans for the fire mitigation or bridge repair projects to the Forest Service, Harper said, because it is not required to do SO. ntps/durangoherad.comardesa3i3e,ugedenesregsbyydumgpetahnboresume-remigptonendgereparum.campaign-dalyneadlin. 3/5 7/21/2020 San Juan County Mail SJMCWMA Gmail Willy Tookey SJMCWMA 3r messages ron mabry Fri, Jul 17, 2020 at 9:21 AM To:' admingsnuancdonsous ann@snuancdloadousy Cc: Chun@ourycounyeogor chungouraycounypogor Sent from Mail for Windows 10 Good morning, I'm writing to seek your input on that is mounted the weed program through the SJMCWMA. I retired from Ouray County on July 1st sO this is one of those loose ends I'm trying to tie up SO here is my thoughts. We own a sprayer that is mounted on a Ouray County truck. This truck was originally meant for the Alpine Host and was purchased with a grant jointly with Ouray and San Juan. It is a 2002 Ford with a market value of around $1000. I met with Connie yesterday and Ouray County would be willing to donate it to San Juan for weed control. We have a little over $16,000 in the bank. I would like to use that money up and finish the season. Then the sprayer would be donated to the county at the end of the season. To do that would have to be put on your payroll or hired as a contract employee to be covered by insurance. Of course the county will be reimbursed with the funds already earned. hope this makes sense. I know you have a BOCC meeting next Wednesday. I could call in to answer any questions if that would help expedite the process. Please let me know what your thoughts are.

This site model reaffirms that Impoundment No. 4 has little, if any, impact on underlying groundwater and there is no evidence that indicates Impoundment No. 4 is the source of high concentrations of metals in the Animas River. The Conceptual Site Model is attached. This further corroborates that SGC has successfully reclaimed the Mayflower Area, and we continue to believe the site would be an ideal repository for the EPA's water treatment plant precipitate.

It is based on annual Investigation Summary and Data Interpretation Reports submitted to EPA, as well as data collected by EPA, the U.S. Geological Survey, and other entities. The comprehensive site data shows that Impoundment No. 4 has little, if any, impact on underlying groundwater and there is no evidence that indicates Impoundment No. 4 is the source of elevated concentrations of metals in the Animas River. Concentrations of metals to the south of the Impoundment No. 4, most notably through Seep 6150 and monitoring well MTMW-20A, are geochemically distinct from concentrations found in groundwater underlying Impoundment No. 4. Groundwater monitoring of the area also indicates that zinc concentrations in groundwater underlying Impoundment No. 4 are less than or similar to those in the Animas River, including upgradient of the Mayflower Study Area, clearly demonstrating that Impoundment No. 4 has little, if any, impact on the Animas River. Additionally, it is unlikely that the weathering of sulfides contained in Impoundment No. 4 is a source of acid drainage. Due to the material's relatively higher neutralization potential, acid-base accounting (ABA) tests indicate that most of the Impoundment No. 4 would not be expected to generate acid drainage. The Silverton area is both historically and geologically complex. Over 20 mills have operated in areas upstream of the Study Area and Impoundment No. 4, and the Silverton Caldera has a long 150-year history of mining activities. It is well known that the Silverton Caldera contains abundant mineral deposits that are naturally high in metals content, which affect the Study Area and impact water quality in the Animas River. Sunnyside Gold Corporation ("SGC"), which was formed and acquired the Sunnyside Mine and Mayflower Mill in 1985 operated the Mine and Mill from 1986 until 1991 using modern techniques and under strict environmental regulation. SGC has engaged in more than 30 years of reclamation and remediation, which has been shown to have improved the water quality in the Animas River. This includes completing reclamation and remediation work at Impoundment No. 4.

As part of this construction, County Road No. 2 was rerouted to the south, around the planned Impoundment toe area and, as shown on Figure 3, a short segment (approximately 660 feet) of the Animas River was diverted southward to its current location. The former channel now underlies the south-central part of the Impoundment. A former stream, now covered, was also present in the Impoundment No. 4 footprint (Figure 3). A seep ("Seep 6150") that emits water with high metals concentrations is present on the current right bank of the Animas River to the south of Impoundment No. 4 (Figure 3). The location of the seep was closer to the left (south) bank of the River prior to its realignment as part of Impoundment No. 4's construction. Some existing peat deposits were removed from the western footprint area of Impoundment No. 4 as part of its initial construction. SGC acquired the Sunnyside Mine and associated facilities, including the Mayflower Mill and Impoundments, on November 19, 1985. SGC leased the mine property from Washington Mining Company (WMC). SGC operated the Sunnyside Mine until 1988, when it and an SGC affiliate, White Pine Gold Corporation (WPG) entered into the Alta Bay Venture (ABV) effective June 1, 1988 with Alta Gold Co. and two of its affiliates, Pacific Silver Corporation and Silver King Mines, Inc. (referred to together as Alta Gold). Alta Gold owned 60% of the ABV and SGC/WPG the other 40%. SGC contributed its interest in the Sunnyside Mine to the ABV. Alta Gold Co. was the manager of the ABV. Effective October 22, 1988, the ABV and WMC entered into the San Juan County Mining Venture (SJCMV), and each of the Alta Bay Venture and WMC contributed its interests in the Sunnyside Mine to the SJCMV. The original participating interests were 65% to the Alta Bay venture, and 35% to WMC. Effective January 1, 1989, WMC became the manager of the SJCMV, and the interests changed to 67% Alta Bay Venture, and 33% WMC. WMC remained the manager of the SJCMV until it terminated effective December 31, 1991. The ABV also terminated effective December 31, 1991. Until 2012, the U.S. Bureau of Land Management owned the land covered by a significant portion of Impoundment No. 4. Tailings from the Mayflower Mill were deposited in Impoundment No. 4 between 1977 and 1991. Based on production records, approximately 60 percent of the tailings in Impoundment No. 4 were in place prior to SGC's 1985 acquisition of the Sunnyside Mine and Mayflower Mill and Impoundments (Jones, 2007). The remainder of the tailings were placed on top of the existing tailings in Impoundment No. 4 by SGC from 1986 to 1991 during the operation period of the Mine and Mill from 1986 to 1991. Additionally, prior to reclamation, Impoundment No. 4 served as a repository for precipitate from water treatment plants located at the Gladstone town site and at the Terry Tunnel. A municipal landfill also operated within the Impoundment No. 4 footprint in the early 1980s. Finally, SGC excavated and relocated approximately 80,000 tons of mostly historic 2-6 Impoundment No. 4 Conceptual Site Model Rev. 0 Mayflower Impoundments Area DRAFT July 2020 mine waste and historic tailings from various sites within the Silverton Caldera to Impoundment No. 4 in the 1990s and early 2000s. The concept of a blanket toe drain underneath Impoundment No. 4 is indicated on design (pre- construction) drawings, but as-built drawings are not available to confirm its existence. Reported information from an SGC employee (Larry Perino), who was present when Impoundment No. 4 was built, indicates that an engineered blanket toe drain was not constructed under Impoundment No. 4. Filter fabric was placed on the north side of the relocated portion of County Road No. 2, between the road and the Impoundment toe. SGC conducted reclamation and remediation work at Impoundment No. 4 concurrent with its operations. The side slopes of Impoundment No. 4 were regraded in 1989 to achieve a stable configuration. The Impoundment was reclaimed between 2004 and 2006, with the majority of the top cover completed in 2004. Reclamation included covering the slopes and top surfaces with locally derived growth medium. The slopes and top surfaces were then revegetated by seeding. A self-sustaining vegetative cover currently exists over the Impoundment surfaces. SGC improved the runon interception and diversion drains at Impoundment No. 4, including the installation of a subsurface concrete diversion wall along a portion of the Impoundment's northern periphery. The ourpose of the diversion wall is to divert groundwater to the surface where it is discharged into a lined ditch and routed around the Impoundment materials. SGC also installed al lined toe ditch and constructed a zero-valence iron reactive barrier to address any groundwater leaving the area to the west. Based on observations, little if any runoff occurs from the Impoundment No. 4 side slopes. Localized areas of ponded water are temporarily present in depressions on the Impoundment No. 4 top surface in the vicinity of monitoring wells MTMW-1 and MTMW-2 immediately following spring snow melt. SGC's entire operations, and all reclamation and remediation work, were conducted in accordance with and pursuant to Colorado permits and state and federal regulatory authority and oversight. 2.2.2 yarology"ydrogedlogy A small former stream has been mapped by the USGS in previous topographic maps now underlies Impoundment No. 4. The alignment of the former stream was interpreted using the 1975 topographic map, as shown on Figure 3. The neadwaters of this drainage were covered by the Impoundment and, to the west of the Impoundment, the drainage is now evident as a series of wetlands and small ponds. Extensive natural iron bogs and fens are present just west of Impoundment No. 4. These features are evident on aerial photographs of the area taken before 2-8 JaNR sewuy peos! ypDIa VoISJOAIO 18 IIeM Jejueg ejaouo Impoundment No. 4 Conceptual Site Model Rev. 0 Maylowerlimpoundments Area DRAFT July 2020 3.0 MPOUNDMENT NO. 4 CHEMICAL CHARACTERISTICS Tailings from the Mayflower Mill make up most of the solids disposed at Impoundment No. 4. Other solids have also been disposed within the Impoundment area, including: 1. Mine waste (tailings and waste rock) from remediation projects conducted elsewhere in the Animas River and Mineral Creek watersheds that was placed on the top surface of Impoundment No. 4 prior to its final reclamation. 2. Water treatment precipitate from the Gladstone and Terry Tunnel water treatment plants that was placed on the top surface of Impoundment No. 4 prior to its final reclamation. 3. Municipal landfill refuse that is now covered by Impoundment No. 4. The mine waste placed on top of Impoundment No. 4 and the water treatment plant precipitate are situated well above the water table. In addition, the water treatment plant precipitate is alkaline and has been determined by EPA to be non-hazardous. The municipal landfill waste is also above the water table and is typically not associated with dissolved metals at the concentrations in groundwater and surface water that have been observed in the Impoundment No. 4 area. For these reasons, the items listed above are not considered further in this CSM. The tailings disposed at Impoundment No. 4 have been sampled and tested to assess their physical and chemical characteristics, and the results from those tests can be used to evaluate the potential for these materials to act as sources of contamination to underlying groundwater and nearby surface water. Descriptions of tailings are provided below. Natural mineralization and the presence of non-Mayflower tailings in the floodplain near Impoundment No. 4 are also described. 3.1 Mayflower Tailings The following subsections describe the placement of Mayflower tailings in Impoundment No. 4 as well as their chemical characteristics. 3.1.1 Placement of Tailings The tailings comprising impoundment No. 4 were produced at the Mayflower Mill by flotation milling of ore from the Sunnyside Mine. The tailings were conveyed to the Impoundment as an aqueous slurry that was distributed around the east, south, and west sides of the impoundment SO as to create a sandy beach with a ponded area against the native hillside.

Mobilization of tailings from Impoundment No. 4 by runoff is negligible due to the presence of functioning run-on/runoff controls and the presence of a 24-inch minus cover as well as the establishment of stabilizing vegetation. Metals may be mobilized from the Impoundment No. 4 tailings through the Impoundment base to the underlying groundwater system. This could occur by the mechanisms of 1) percolation, 2) a pressure response due to infiltrating water that forces water already present in the tailings downward, and/or 3) localized areas in the southeastern part of Impoundment No. 4 where the tailings may be in contact with groundwater. However, the tailings in Impoundment No. 4 reflect little, if any, impact on the underlying groundwater system, which has zinc concentrations that are generally lower than or similar to those in the Animas River upgradient of Impoundment No. 4. Metals that enter the underlying groundwater system will move downgradient in the alluvial deposits of the Animas River valley by the mechanisms of advection and dispersion. Concentrations of most metals will be decreased by sorption and precipitation in the groundwater system matrix. Mobile metals such as cadmium and zinc will tend to stay in solution. Metals that are not sorbed/precipitated in the groundwater system matrix will continue downgradient and may enter the Animas River in its gaining reaches, which typically occur where the valley walls constrict and reduce the cross-sectional area of the groundwater system. Once in the River, metals may be sorbed onto sediment. Metals in the River will re-enter the groundwater system in losing stream reaches, which typically occur where the valley walls diverge and the cross-sectional area of the groundwater system increases. Overall, concentrations of metals in the Animas River surface water and groundwater systems decrease in the downgradient direction due to dilution from tributary stream systems. Figure 19 shows zinc load in the Animas River through the Study Area (see blue line entitled "Mainstem") based on data collected in October 2019. 6 This figure also shows the cumulative sum of measured zinc load in tributary inputs to the Animas River (see orange line entitled "Sum of inputs"). The difference in load between the orange and blue lines indicates that the vast 6 Zinc load is expressed in units of pounds per day (Ib/day) and is calculated by multiplying measured zinc concentrations by stream flow along with appropriate unit conversion factors. 5-1 Impoundment No. 4 Conceptual Site Model Rev. 0 Mayflower Impoundments Area DRAFT July 2020 majority of the increase in zinc load through the Study Area occurs as diffuse inflow to the River rather than as discrete tributary inputs. Figure 19 includes a grey line entitled "Zn scale baseline, which is based on measured loads of strontium and molybdenum in the Animas River. These elements are not considered to be associated with mining-related impacts and thus provide a baseline for natural metal loads in the River. In general, zinc loads in the Animas River show only slight increases through the Study Area, consistent with baseline surface water metals until the vicinity of Seep 6150. Just downstream of the Seep 6150 location, zinc loads in the Animas River increase markedly (Figure 19). The zinc load distribution in the Animas River demonstrates that potential sources in the eastern portion of the Study Area (e.g., the Mayflower Mill and Impoundment Nos. 1, 2, and 3) are not impacting water quality in the Animas River. As described above, the Impoundment No. 4 tailings are also not impacting the Animas River. The measured impacts at Seep 6150 and in the area downstream of the seep appear to be associated with other sources, such as natural mineralization and/or historic floodplain tailings. 5.2 Naturally Occurring Sources Metals from naturally occurring sources in the Impoundment No. 4 area would enter the glacial till and alluvial groundwater system and move downgradient according to the mechanisms described above for the Mayflower tailings. 5.3 Historic Tailings As previously discussed, the lateral and vertical extents of the historic floodplain tailings near Impoundment No. 4 are currently unknown. Precipitation and snowmelt likely descend through these floodplain deposits, mobilizing metals to the underlying groundwater system and possibly to the Seep 6150 location. It is also possible that the floodplain tailings are in contact with the groundwater system during some or all of the year. The extent to which contaminants originating from the floodplain tailings have been mobilized downgradient is not well understood. 5-3 impoundment No. 4 Conceptual Site Model Rev. 0 Mayflower Impoundments Area DRAFT July 2020 Effects of Historical Mining in the Animas River Watershed, San Juan County, Colorado.

Page 1 of2 JUAN OU RCmKe EINY Economic Recovery Team Meeting Date: 7/14/2020 10-11AM Short Term: Many states are moving backwards with COVID we need to stay vigilant. 1. Kim, only one family has reached out for assistance at this time, 30k left to use later as needed. 2. Deanne said businesses are doing well, with limited hours or days without proper staffing. Working to keep businesses in compliance this week. Durango is pulling back marketing efforts, other communities too. We've been gentle marketing. 3. Becky said all mountain towns are seeing record high crowds, maybe because of the long quarantine. They need to do more research to see if this is something to expect or if its short term when it comes to future planning. 4. Lisa updates: The outdoor recreation community also says the numbers are way up for outdoor rec usage. P&W said their numbers are up over 1000%. Overall expecting an increase into the future. Long Term: 1. Fiber: Kim explains that strong fiber is here in town, but not dispersed through the community and feels like more effort needs to be put here. It was difficult with online learning when the kids had to continue schooling from home. a. Satellite on school roof could broadcast a signal out for families and students to have internet. Need to consider the same idea for the whole town. b. Town updates that they don't have other ideas going right now, Kim's idea is new and they're on board with the idea. John R, Kim, & Willy will try to work together about these ideas and making more short-term plans like strategic broadcasting and redundancy on the one fiber line that runs from the south up to CL building. Theyll get started meeting some time on this next month. C. Shane explained that SMPA had a timeline of about 3 years for our redundancy at the Stakeholders meeting. Willy added that it should be constructed next summer but getting it from Ophir into town is the missing piece. 2. Worklorce/workforce Housing: John R had a conversation within the construction industry who's looking for opportunity zones for investors. He wants to start working with realtors and identify inventory of parcels, other than Anvil. The question was posed considering Anvil, would those homes sell if 1. Darlene wanted to know if there was going to be a plan for Blair St. John says Casey (engine) would be difficult to get here but they are working to get some cars moved to Blair. They are trying to get together with the train and hope to get something underway. Deanne/John will try to get in touch with the General Manager/D&SNG today. 2. Shane, trend in CA (Data Dividends Project) where data farmed would turn into dividends back to us per piece of data. This would be an interesting idea to support to gain additional revenues. 2020 Census Self-Response Rates 4/21/20 Internet 7/15/20 Internet Final 2010 USA 52% 62 Colorado 55.2% 65 67 Archuleta 26.8% 26.6% 39 31 43 Dolores 14.5% 11.3% 40 19 39 La Plata 44.5% 43.5% 56 49 58 Montezuma 47.1% 43.5% 59 48 63 San Juan 7.7% 7.7% 26 15 32 Self-Response Rates Map - https://2020censusgov/en/response-rates.htm!
