Meisner, Garco PHN 902 Taughenbaugh, Suite 104 Rifle, Co., 81650 Dear Mrs Meisner: In reply to your Letters of February 20 and March 19, we respect- fully submit the following; 1. Your letter of February 20 didnot indicate anti suspense dates, or indicate any sense of urgency. We consulted outside advise, and concluded that your intension was to allow us to proceed with the nonuse statis untill such time as we determined the course of action we had outlined in our testimony at your hearing. 2. As you will note, a completed application and the rules for submission, and execution are included in this letter, and we ask you to note that the County will not accept applications that are not in conjunction with a building permit. As we have tried to explain to you this fact on several occasions and you have choose to ignore, we do not have a clue on who will be responsible for issuing the permit. The permit fee is also included, so that you will be able to see we are serious about this matter. 3. In the rules there is sufficient data so that even an un- educated person like myself, could properly install and operate a I.S.D.S. with out assistance. It further -supports our contention that your engineer had no intension of inspection or approval of our system and lied in his testamony at your hearing. We can only surmise that it was your intention to recognize the inconsistences and try to arrive at an equitable solution, which could allow both parties to accept. 4. We assume that you have sufficient expertise to make an inspection, and accept our assurances that the system will not be used in any way, until such time as you are fully satisfied that we have in no way endangered the public which is the whole purpose of these rules and regulations. We would also like to note that your office is not listed as an authority in the rules, and we wonder about this. It makes these rules ambiguous, vague and uninforcable, according to law, (our legal counsel), and his advice was to appeal, but we felt it was counter to the best interests of the citizens. 5. We feel we cannot accept Mr. Schwaller as either an expect, or unbised observer, as he has already testified in court that this entire action by the County Building Department is about power and money, and nothing has changed since that time. 6. We are considering recording all calls and conversations, to preclude the recurrence of facts being altered and forceing us into defensesive positions we donot desire. 7. We are still collecting data and facts to support court proceedings which may or - inc ••e -t s matter. Our legal advice was not to warn b i wiS e1,KFe must be honest and forth right and do so. c. Robert N. Mayo, 2495 Cty Rd 245, NC, 81647 e. Garfield County BUILDING & PLANNING DEPARTMENT Mr. Robert N. Mayo 2095 County Road 245 New Castle, CO. 81647 November 9, 2004 Re: Septic Permit Dear Mr. Mayo: Enclosed is a copy of the permit # 3958 for a septic system located on your property. I believe we mailed the receipt and bottom tag for permit # 3958 to you last May. The bottom tag is the actual permit allowing work to be done at a construction site. The upper portion of the permit shows both the system design and final system inspection and approval. With an engineered system, you probably have the system design by Cronk Construction Incorporated in your file. If this is not the case please contact this office and a copy of the engineered report can be provided to you. Thank you for your compliance to the sewage disposal requirements. Please call if you have any questions. Yours truly, Andrew Schwaller Building Official cc F"bo* ,„i CH.s,r 108 8th Street, Suite 201, Glenwood Springs, Colorado 81601 (970) 945-8212 (970) 285-7972 Fax: (970) 384-3470 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 R NK CONSTRUCTION INCORPORATED 1129 -24 Road • Grand Junction, CO 81505 970.245-0577,970.257-7453 (fax) INDIVIDUAL SEWAGE DISPOSAL SYSTEM DESIGN Date: May 11, 2003 Prepared by: Thomas A. Cronk, P.E. Cronk Construction Inc. 1129 -24- Road Grand Junction, CO 81505 245-0577 Type of Design: agricultural structure Owner: Robert N. Mayo 2095 County Road 245 New Castle, CO 81647 970-984-2737 Property address: 2095 County Road 245, New Castle, CO 81647 Tax schedule No.: Legal Descript: Page 1 of 6 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1.0 Site 'History An individual sewage disposal system was installed at 2095 County Road, 245, New Castle, CO 81647. As based on material invoices, the ISDS was installed during the Spring, of 2002. The ISDS serves an agricultural building and was installed without an ISDS pennit as issued from Garfield County. At the request of Garfield County officials, the owner (Mr. Robert N. Mayo) has retained the services of Mr. Thomas A. Crank, Colorado registered professional engineer (R.P.E.), to inspect the existing ISDS. The inspection is meant to determine if the existing ISDS affords compliance with Garfield County regulations and requirements. The site consists of approximately 3.61 acres of cultivated native soil. Drainage is approximately 3% to the east. A site visit was conducted by Mr. Thomas A. Cronk (R.P.E.) on 05/05/04. At the request of Mr. Cronk and previous to the 05/05/04 site visit, Mr. Mayo had exposed the septic tank and ends of the absorption field of the existing ISDS as well as prepared perc test/soils evaluation excavations. During the site visit the existing ISDS was inspected with physical characteristics documented through creation of an as -built drawing. A perc test/soils evaluation was conducted to evaluate subsoil conditions and determine the treatment/disposal capacity of the existing ISDS. The locations of the soils observation excavation and the perc test pits are shown on the attached plot plan. Results of the 05/05/04 site inspection and a discussion of the effective capacity of the existing ISDS follow. The 05/05/04 perc results are attached for reference as Appendix A. 2.0 Development of Design Parameters A soils observation excavation trench was extended to a depth of 96" below ground surface (BGS). There was no evidence of ground water or high seasonal water table in the open excavation to a depth of 96" BGS. The soils evaluation indicates two distinct soil horizons underlie the site. A lithological description follows: depth (in.) description 0" - 36" silty clay, gray; hard and blocky 36" - 96" gravel to cobbles to boulders in gray to brown silty clay matrix As based on the 05/05/04 perc tests (Appendix A), a design perc rate of 25 min/in. is deemed appropriate for evaluation of the capacity of the existing ISDS. Page 2 of 6 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 3.0 Evaluation of Svstem Design A INFILTRATOR absorption field has been constructed at the site. The absorption field consists of two rows of INFILTRATORS installed in a trench configuration of six (6) INFILTRATORS each. The absorption field was installed level from end-to-end with depth of cover over the infiltrators ranging from 20" to 26" as dictated by existing site topography. Site topography and final landscape grading will afford adequate drainage away from the absorption area. The absorption field as observed was constructed in accordance with INFILTRATOR guidelines and manufacturer's recommendations. Additionally, the absorption field as constructed appears to afford compliance with Garfield County and Colorado Department of Public Health and Environment (CDPHE) regulations and requirements. Thomas A. Cronk (R.P.E.) observed the installed INFILTRATOR absorption field and documented physical characteristics of the absorption field through creation of an as -built drawing during the 05/05/04 site visit. As documented by construction receipts furnished by Mr. Mayo, the septic tank installed for the project is a 1,250 gallon one piece concrete tank obtained from Copeland Concrete Inc. The tank as constructed is consistent with two compartment CDPHE septic tank requirements. Construction receipts indicate effluent piping is four (4) inch SDR35 (ASTM 3034). Septic tank construction and effluent piping was observed by Thomas A. Cronk, R.P.E., during the 05/05/04 site visit. Installation appeared to be consistent with Garfield County and CDPHE regulations and requirements. The septic tank appeared Level and stable. Effluent lines appeared to maintain a minimum of 2% (1/4" in 12") of fall from the structure to the tank and hence to the absorption field. As shown on the attached plot plan and as -built drawing, the ISDS as installed does not infringe on any setback requirements as set forth in Garfield County or CDPHE regulations. Domestic water is supplied to the structure from an on-site well located approximately 1000' south of the ISDS. The domestic water line is in excess of 25' from the absorption area and in excess of 10' from the septic tank/effluent sewer line. East Elk Creek lies approximately 140' east of the ISDS. Setbacks from the structure of 5' minimum to the septic tank and 20' minimum to the absorption field are maintained. Finally, irrigation of adjacent farm land has been controlled to maintain a minimum setback of 10' from intermittent irrigation laterals to the absorption area. As discussed above, INFILTRATOR absorption trenches have been installed to discharge septic effluent to the underlying sub -soils. The absorption trenches consist of two (2) trenches 3' wide x 32" min. deep x 37.5' long with six (6) standard INFILTRATOR units each for a total of twelve (12) INFILTRATORS. The absorption field encompasses a gross area of 225 square feet with an effective area (31 sq. ft. allowed area/INFILTRATOR) of 372 sq. ft. Under a designperc rate of 25 min/in., the existing absorption field is capable of effectively treating and disposing of a peak sewage flow of 372 gallons per day (average daily sewage flow of 248 gallons/day). Calculations and design parameters used to size the absorption field follow.

As stated by Mr. Mayo, the proposed use of the agricultural building includes'/ bath services for the owner (Mr. Mayo) and one part time employee. Additionally, a two compartment wash sink will be used to wash tools and equipment used in the agricultural operations. Calculations of sewage loadings for these uses follows: source loading factor average daily sewage flow (gal/dav) 2 agricultural employees (8hr. shift w/o shower) 20 gal/8-hr shift 40 gal/day two compartment wash sink 10 gal/wash @ 2 washes/day 20 gal/day Total Average Daily Flow 60 gal/day The calculated daily average flow loading of 60 gal/day is well below the calculated disposal capacity of the absorption area of 248 gal/day (average flow). Additionally, the 1,250 gallon septic tank is capable of providing the required 30 hour retention time for a peak design sewage flow of 1,000 gal/day peak or 667 gal/day average flow. Again the septic tank volume is well in excess of the septic tank capacity required for the calculated average flow loading of 60 gal/day. In conclusion, the ISDS as installed and documented by the attached as -built drawing is adequate to treat and dispose of a maximum average daily sewage loading of 248 gal/day. As based on the above calculated sewage loadings for the proposed use of the agricultural building (i.e., 60 gal/day average flow), the existing ISDS is more than adequate to serve the building and afford compliance with Garfield County and CDPHE ISDS regulations and requirements. 4.0 Suggested Maintenance and Inspections Protocol for Operation of ISDS It is suggested the owner consider and comply with the following operation, maintenance, and inspection criteria to assure maximum life time and efficiency of the ISDS. • The owner shall take precautions to prevent vehicular traffic, excessive surface watering, accidental flooding, or other activities from compacting, saturating, or otherwise altering the subsurface soil parameters used in designing the septic system. • The owner will plant and maintain grass or other shallow rooted cover crop to prevent erosion and promote evapotranspiration over the absorption field. • The owner will inspect and maintain the required mounding and drainage away from the absorption field to prevent saturation from precipitation and surface flows. • The owner will inspect and prevent intrusion of burrowing animals and deep rooted plants into the absorption field. • The owner will conduct periodic maintenance of the septic system by removing accumulated sludge from the septic tank every 3-4 years to prevent clogging of the absorption field.

Drainage is approximately 3% to the east. A percolation test/soils evaluation was conducted on the property of reference on 05/05/04 by Tom A. Cronk, registered professional engineer (R.P.E.). The locations of the soils observation excavation and the pert test pits are shown on the attached plot plan. A soils observation excavation trench was extended to a depth of 96" below ground surface (BGS). There was no evidence of ground water or high seasonal water table in the open excavation to a depth of 96" BGS. The soils evaluation indicates two distinct soil horizons underlie the site. A lithological description follows: depth (in.) description 0" - 36" silty clay, gray; hard and blocky 36" - 96" gravel to cobbles to boulders in gray to brown silty clay matrix Pere holes were constructed in test pits #1, #2 and #3 at a depth of 36" BGS. The holes appeared to be well saturated at the time of the test. Results of the percolation test are shown in Table 1.
