Galena Aspen, CO 81611 Re: Rice Residence Wastewater Facilities Dear Ms. MacKenzie: APR 1 & 199 At 7 1L ENVIRONMENTAL HEALTH ASPEN / PiTKIN! Enclosed please find my comments and the red -lined as -built drawings based on my recent inspection of the wastewater facilities at the Rice residence in Snowmass, Colorado. I was able to inspect and measure all of the above -ground facilities as well as the septic tank interiors through the access ports and the wetland media by minor excavations. The detailed structure of the sand filter was not inspected; however, discussions with the owner and constructor indicated that the filter was built to plan. Based on this inspection and discussions with the owner and constructor, it is my professional opinion that the system was constructed as designed with the exceptions noted on the enclosed comments and drawings. The largest change from the original design is the location of the wetland cell. The as -built location of the wetland should not affect the performance of the system. If you have any questions on this matter, please feel free to call me and I will be happy to answer them. Sincerely, AQUATIC and WETLAND COMPANY Bill og e , Ph.D., P.E.

I reminded you " that for the sewage permit to be finaled, this Department still required the following: 1) final as -built drawings of the constructed wetlands sewage system since changes were made during construction 2) letter from the engineer stating that the system had -been installed according to the engineer design. We have still not received the requested material. This letter is to inform you that you are in.violatioT) of the Pitkin County Individual Sewage Disposal System Regulations. 114-16 INSPECTION STAGES .... if an engineer designs the system, he/she must provide the Department with proof that a final inspection was done by -the engineer. A final as -built -drawing of the system is required for all ISDS's installed in Pitkin county prior to -final approval." Resolution #94-187 of the Board of County Commissioners of Pitkin County allowed this Department to permit a limited number of Wetland Wastewater Treatment Systems.in Pitkin County under the condition.they meet certain standards in addition to pollution prevention standards already.exi"sting in the ISDS regulation.

SPECIAL MEETING SEPTEMBER 19, 1994 chairman Child called the meeting to order at 10:00 ON M M ERs PRESENT: Commissioners Bob Child, Wayne , Jim True and Bill Tuite . Commissioner Mick Ireland AP Chairman Child convened the meeting as the Board of Health to i4sseOs the wetland wastewater treatment system as proposed by Aquatic and wetland Wastewater Treatment, Inc. Tom Dunlop, Director of the Environmental Health Department, intr�'duced this item as a continuing discussion from the meeting on eptember 13th. He presented commission members with a �emo�andum which he had drafted too late to get incorporated into the IIpacket. A. copy of this memorandum is made a part of this recdid as EXHIBIT "A" Dun Op said Article 9-1 of the Pitkin County regulations on sewage disposal allow the Board of Health to permit new sewage treatment technology in the County under an experimental designation. He saidthere is a representative from Wetland Wastewater Treatment, Inc.;' here today to respond to some of the questions that the Board iadloxpressed previously such as how the system would work in cold weaher, how ground water is protected, where the treated water 4oel after it leaves the septic tanks, where the lined wetlands willj;be, the sand filter, chances of system failure, and any other iuegltions that the Board may have. The wetlands construction is intended to replace a common leajh:field. The effluent goes into a septic tank and does into a lined wetlands that has gravel in it and grasses growing in it to helO'decompose the organic material. And then that effluent goes into a sand filter where it ultimately discharges into the ground, as does a more traditional leachfield. Dunlop said the request before thin system may be installed in of staff are, after reviewing i' BO;ikD OF COUNTY COMMISSIONERS the Board today is to determine if Pitkin County. The recommendations current data and the EPA Design 1 SEPTEMBER '19 j, '1994 10-21-1994 01:30PM FROM Pitkin County Finance TO 5197 P.02 Manual, is that the Board allow this type of system to be installed in Pitkin County, but maybe limit the numbers of them to six. And that would give staff the opportunity to have them installed at vari'�us locations in the County where the system could be tested un= different conditions. He said staff has come up with six con4tions as outlined in the memorandum. He proceeded to review those conditions with Commission members as outlined in his memorandum. Child asked what recourse the Board would have if the system is installed and there is a failure? Dunlop responded that it would be considered such as any other fail d system. Under the county regulations, that currently exist, it -ould allow the Environmental health Department to take initsative action against the property owner to make a repair in dompliance with the County regulation. And that is already in the books. so if there is reason to believe that there is contl4mination of ground water, it can be addressed through the existing code. Tim iWhitsitt, County Attorney, asked Dunlop if he would expand a littlie bit on the status of these kinds of systems and the State Board of Health adoption of these kind of constructed wetland systems; where that stands at the state. i Dunl;pp replied that the State Board of Health, just recently within the fast few months, adopted new guidelines, and staff is going to be rewriting the County regulations to hopefully be adopted by April 15 of 1995. And included in the state guidelines wetlands treatment systems are addressed. And there are standards that are established there as well regarding sampling, and making sure that thej;contaminants are not exceeding specific standards or limits. So there has been a recognition of this type of technology by the State Board of Health. If the County does nothing to change its tegulations between now and a year from June 30th, the state guideline will become the Pitkin County Regulation on Sewage Dis�;bsal and that section on wetlands will be in there. i. Ethijidge said for him it is simply not possible to separate these stan4ards on a pending application, in fact you tie those two together. so if this is approved today, the Board will be approving a specific site application for Little Elk Creek. Dunlop said what they intend to do, if the Board approves the guidelines, is to allow a public comment period from the neighbors. He staid they are not asking the Board to approve any specific site becaiuse what direction the Board gives is going to apply County wide. Eth idge referred to Item 5 in the previous memo, which had to do witmonitoring. He said it shouldn't be by the applicant. HO BOARD OP COUNTY COMMISSIONERS 2 SEPTEMBER 19, 1994 my mance TO L 5197 P.03 thinks there needs to be a new standard No_ 8 that on-site monitoring by the Environmental Health shall be allowed by the applicants. And with regard to the last standard, sampling he thinks is something that the county should be involved in on an experimental basis. He said the Board has asked for specifics on the (lot that this is to be applied, and he hopes they will be provided today in terms of where ground water is, located, surroundings and whether or not there is a standing water wetlands and 1�ow ground water gets controlled. Because standing Water would inhabit mosquitoes. Dunlop said that Steve Pounce -pour should be able to answer some of these questions in his presentation. But with regard to the monitoring, he is concerned about setting a precedent. He said theyl depend on owners of public water systems, community systems and Isewage treatment plants to do all their own monitoring. And then± they submit reports to the environmental health department. Them is a commitment on their part to maintain their operation and to gave the department routine monitoring sampling, and that is why they didn't say that their department was going to take on this one. 1 After a discussion, it was agreed that monitoring by the tnvijronmental Health Department will be added as a standard. Ethridge noticed an error on the agenda with regard to the ballot questions. He noted that there are a lot of people in the audience which appear to be in attendance for those hearings. He explained than there had been a motion in the last regular meeting to continue these matters to 2:00 p.m. He apologized for any inca'nvenience this has caused for anyone. ChaiIrman Child adjourned the meeting as the Board of Health do"issioner Tuite moved to table the public hearings on the ballot questions to 2:00 p.m. With a second by Tuite, the motion passed unanimously. Chairman Child reconvenod the meeting as the commissioners sitting as -the Board of Health. Stevie Pounce -Pour, a representative of Aquatic and Wetland Wastiewater Treatment, Inc., proceeded with his presentation regarding the system. A copy of his documentation associated with hislpresentation is made a part of this record as EXHIBIT "B". He said a constructed wetlands system starts out in the same fashion with a typical septic tank, usually 1,000 gallons fot a three- be4�oom home. Then overflows into the constructed wetland bed. This bed is typically rectangular with a perforated pipe and the inlOt that allows the water to be distributed across the headwaters of the wetland. Then over a period of approximately seven days, the !water flows slowly through a gravel matrix that has wetland BOARD OF COUNTY COMMISSIONERS 3 SEPTEMBER 19, 1994 19WAMI- 10-21-1994 01:31PM FROM Pitkin County Finance TO 519? P.04 plants growing in it. The water is never visible because it is below the surface of the gravel by about six inches. He said you can walk straight across this thing and your feet will stay dry. And that is important, because it does not provide a habitat for mosquitoes; you will not get mosquitoes from this system. As the water passes through, there is a treatment effect caused by the bacteria that exists in the wetland. The treatment effect is not a result of the plants. it is a result of the bacteria:,that grow on the roots of the plants. Tuit� asked what would happen in the wintertime. PounIpe-pour responded that in the winter bacteria slow down, and theii- treatment therefore, slows down as well. So when you design one of these things you have to design it such that it's built to the treatment rate that will be happening during the winter. He said; the plants are not responsible for the treatment; it's the bact' ria that exist on the roots of those plants. Wetland plants are :specially adapted to aquatic environments in that their roots do npt decompose over the winter and the plant will groin back come springtime. So as long as the system is designed for the winter conditions they will continue to get adequate treatment'. Ethridge asked what the effect was on the wintertime dormancy. The problem being, that there is warm water coming out of the septic tanks and he does not know what effect, if any, that will have on the 4ormancy of the plants. In other words he said, you may create a situation in a very cold climate, which certainly. exists in Little Elk Creek, that may damage the plants and therefore, the root, system would be lost. Pounce -pour responded that there is not a problem in cold climates as Oar as the plants growing. In fact, it actually serves as a slight season extension to have that warm water flowing over the roods. You will actually get active growth and metabolism from the plants for a longer period of time than you might otherwise. He said he has never heard of a case in plant life being a problem in cola climates. Child asked what the effect would be if the liner was punctured? Pounce -pour responded that the liner carries a 20 year warranty, if the line is under ground. And the entirety of this liner is underground. Also, the system is usually underlained by two to three inches of sand. Duniop said that if the system does leak, the permit is terminated. He �ai.d his bigger concern is not once it gets in place, ;but during the installation. He said the installers need to know exactly what they are doing so they do not puncture the liner. So they have to co�ivince him, that to do that liner, they need to have;people who BOARD OF COUNTY COMMISSIONERS 4 SEPTEMBER 19, 1994 i 4M 10-21-1994 01:32PM FROM �Pitkin County Finance TO 519? P.05 L. know: how to fuse the seams together and they have some way of verying that there are not little leaks in it before it is if covered over. Pounce -pour said the liner is a factory produced single. sheet. There are no seams in it, with the exception of two seams at the inlei and outlet pipe which are both factory sealed. He said if theyibuild it right and with quality materials there should be no leak's. Dunlpp said if' there is a suspicion that it is leaking they can injep� di,e,into it and see if it slowly starts to come out to the surf �C:.; somebodyls well ground water, etc. Pounce --pour said he would be present at the installation to make sure that it is installed right. nunlbp said the environmental health department will plan to be present at the installation also. Browhh Rice, applicant, proceeded to review his site plan with commission members. Pounce -pour continued that they have been able to produce a minor Mir le here. They can come in with a competitive cost to the con entional systems and offer tremendously increased water treatment. They can also offer the ability to somewhat reuse some of the water that flows through there. As not only are the systems treatments, but they can also provide landscape irrigation. He said there are hundreds of these systems in use in the United States. The systems range from small residential systems to other systems over 100,000,000 gpm per day. He proceeded to review the list' of other systems and the areas where they have been installed. Chi]!d opened the hearing to public comment. There. being no comment, he closed the public hearing and brought the matter back to the Board for consideration. i A discussion ensued with regard to the conditions of approval. Ethridge referred to Item No. 1 regarding a backup system. He asked what the minimum required for the backup system? :Because he thinks this should be stated in the resolution. Dunlop said there is already an existing standard. It'was agreed that this condition should be changed to read "The lot; on which a constructed wetlands is installed must be large enough, as it exists in the sewage and disposal regulations." with regard to Condition No. 2, it was agreed that the word BO D OF COUNTY COMMISSIONERS 5 SEPTEMBER 19, 1994 10-21-1994 01:32PM FROM Pitkin County Finance TO 5197 P.06 "should" will be changed to "shall". It oras agreed that Conditions No. 3, 4, and 5 were appropriate as written. Ethridge asked Mr. Rice if the homeowners had been notified of their proposal? Mr. Rice responded that he contacted the secretary of the homeowners association. Also, Nancy McKenzie told him 4 month or so ago that she was also contacting them. So it should have been done° from both sides. Ethridge said he is proposing a 30 day comment period. He told Mr. Rice; if he can confirm that this has been done he thinks that would be:sufficient. He does not want to have 30 simultaneously. With.regard to condition No. 6, Dunlop was asked to meet with the county attorney to come up with a Concept which is a 30 iday notice period so it works best for the environmental health department and the 'applicant. It bras agreed that Mr. Rice will get a statement from the Little Owl Creek Homeowners Association with regard to his application. Pounce -pour expressed a concern with regard to the 30 day comment period. Ethr:,idge told him that the problem is that this system does not exist, there are no regulations which will allow this. And the County is trying to accommodate him and at the same time: the Board is�taking a very conservative approach. Also, the reguiations can be changed if appropriate. It iras agreed that on site monitoring and sampling shall be conducted by the Environmental Health Department for the first two systems that go in for the first four seasons. Pouri.ce-pour again expressed a concern about the 30 day notice period. Etiridge noted that if he could prove that he had already notified the neighbors or the homeowners and can provide proof of:that, then the only thing he would facing then is just the normal.proc;essing time through the environmental health department. If when he comes in;for approval and he hadn't notified the neighbors then he would be:tacing a 30 comment period. DuAlop noted that the way the guidelines are being discussed today, ifIafter a year there is no odor or complaints. They could revisit thi 30 day period and lessen it or make it less experimental. BOA D OF COUNTY COMMISSIONERS 6 SEPTEMBER 19,1994 I I: 10-21-1994 01:33PM FROM Pitkin County Finance TO 5197 P.O? Chid opened the hearing to public comment. There being no comment, he closed the public hearing and brought the matter back to 1the Board for consideration. Eth� dge moved to adopt the experimental guidelines with amendments as :discussed. With a second by Tuite, the motion passed unanimously. ADJbURNMENT: Comuaissioner Ethridge moved to adjourn the meeting at 11:55 a.m. With' a second by Commissioner Tuite, the motion passed unanimously. Respectfully submitted, Jeainotte Jones C14rik to the board of County Commissioners i i BO D OF COUNTY COMMISSIONERS 7 SEPTEMBER 19, 1994 TOTAL P.O? r MEMORANDUM TO: Board of County Commissioners acting as the Board of Health FROM: Thomas S. Dunlop, Director� ,(� Environmental Health Department DATE: September 19, 1994 .1 RE: Experimental Individual Sewage Disposal System Design Description of Issue: Article 9-1 of the Pitkin County Reaulations on Individual Sewage Disposal Systems (ISDS) states that manufacturers may petition the Board of Health for an experimental installation permit for a new sewage treatment design. Aquatic and Wetland Wastewater Treatment, Inc. of Boulder, Colo. has submitted a septic permit application for installation of an experimental wastewater system in Pitkin County. Before this department can issue a permit to install, the Board of Health must authorize the standards under which the permit may be considered. There will be a representative present from the design company at the September 19th work session to respond to questions concerning the technology behind the design. He will be prepared to discuss such issues as: how the system works in cold weather; how ground water is protected; where the treated water goes after it leaves the septic tank, lined wetlands bed, and sand filter; chances of system failure; margin of error in system component design; and other concerns from the Board. At the most fundamental level, the experimental system is called a "Constructed Wetlands", and is defined as follows. It is a wetland specifically constructed for the purpose of pollution control and waste management, at a location other than existing natural wetlands. It is intended to replace the common leach field. The effluent from the house goes into a conventional 2 -chambered septic tank which slows down the movement of raw sewage so that solids can separate or settle out and not travel into the leach field. The clarified effluent then goes by pipe under the surface of the constructed wetland, a gravel bed planted with several species of wetland plants. The effluent then travels by pipe into a sand filter where it percolates into the ground. Because the final effluent is clean, the final disposal bed is designed at about one-third to one-half the size that would be required for a conventional sewage treatment bed. The request to the Board of Health is to review presented material from this office and the applicant and determine if this sewage treatment system can be installed in Pitkin County. W Wetlands ISDS September 19, 1994 Page 2 M Recommended Staff Action: This department has reviewed the data on this type of system and the U.S. Environmental Protection Agency (EPA) Design Manual for constructed wetland systems. The EPA states that the design procedures and related guidance in their report are considered to be valid, but subject to further improvement. Staff recommends that the Board of Health allow the Aspen/Pitkin Environmental Health Department (APEHD) to permit a limited number (6) of wetland wastewater treatment systems in Pitkin County. That is, with the condition they meet the following standards in addition to pollution prevention standards already existing in the ISDS regulation, and as they may be amended: 1) The lot on which a constructed wetlands is installed must be large enough to accommodate a more traditional sewage disposal system based on adopted Pitkin County ISDS regulations, such as a septic tank and leach field, or an engineer designed system using currently accepted technology. Should the experimental system fail, and not be able to be repaired, the homeowner must abandon the experiment and immediately install a non -experimental system. 2) The constructed wetlands must be designed by a Colorado registered professional engineer. The recommended design approach shall follow the "plug flow model" which allows adjustment in the design for different temperature conditions which could be a factor in Pitkin County. 3) There must be no discharge of effluent off the property, unless the applicant has obtained a National Pollution Elimination Discharge System (NPEDS) permit from the Colorado Department of Public Health and Environment (CDPHE). If a NPEDS permit is obtained the applicant will be required to monitor treatment system effluent prior to discharge to receiving waters of the State. Sampling parameters will be established using CDPHE, Water Quality Control Division guidelines. 4) No permit for a "Constructed Wetlands" system will be issued by the APEHD if it is determined that a health hazard will be created, a private or public nuisance will result, or undue risk of contamination exists. 5) Should odor complaints, as the result of treatment system operations, be received by the APEHD, Regulation No. 2 (as amended), titled "Odor Emission Regulations" of the CDPHE, Air Pollution Control Commission, will be the legal instrument used in the investigation. U Wetlands ISDS September 19, 1994 Page 3 M 6) The applicant shall notify immediate neighbors, or the homeowners association if the property is regulated by covenants, and allow them to review and comment on the installation. This comment period shall total 30 days starting from the date of application with the Environmental Health Department, and expire 14 days prior to the date of system installation. Comments shall be provided to the APEHD for consideration prior to a permit being issued. 7) The application must comply with the Colorado "Guidelines On Individual Sewage Disposal Systems", Chapter IX titled, Absorntion or Sand Filter System and Non -discharging Systems. 8) For the first two wetlands systems installed in Pitkin County, the Environmental Health Department will monitor the systems for four seasons (one year). The Owner will pay for the analysis of all samples. At a minimum, sampling will consist of dying the wetlands bed and watching for the dye to appear at monitoring ports located at 4 corners of the bed. The monitoring ports may consist of perforated PVC pipe positioned vertically to a depth of at least 4 feet outside the lined wetlands bed.

Owner and Contractor shall construct this wastewater treatment system according to these drawings and specifications without amending or modifying said drawings and specifications, unless specific written permission is provided by the Engineer. If conflicts occur during installation between applicable codes and these drawings and specifications, it is the Contractor's and/or Owner's responsibility to bring them to the attention of the Engineer in a timely manner so as not to delay unduly the Construction Phase. These specifications are the property of the Southwest Wetlands Group, Inc., 1590 San Mateo Lane, Santa Fe, NM 87501, and may not be used or reproduced without the specific written permission of the authors. Revised: March 18, 1994 C:\WP50\SPECS.RES NOTE: The following CONSTRUCTION SPECIFICATIONS are intended to be used in conjunction with the DRAWINGS. GENERAL DESCRIPTION OF THE WORK _ Constructed Wetlands are intended to replace the common leach field that is used with a septic tank. The construction process is quite simple and should be easy for the Contractor to accomplish. a The Constructed Wetland is simply a shallow rectangular excavation two feet deep in which a plastic liner is placed. Two lengths of perforated pipe are placed on the liner, one at each end of the wetlands. The perforated pipe at the front end of the wetland is called the distribution pipe. It is connected to the septic tank. The collection pipe, at the other end, is connected via a level adjusting sump and pumped into the sand mound. The liner and perforated pipe are covered with 24" of gravel and planted with several species of wetlands plants. Black water from the septic tank flows through the gravel bed where it is purified by plants and bacteria. The liner prevents groundwater contamination and therefore must be kept water tight. The water flows through the gravel bed under the surface of the gravel. The depth of the water is regulated by the level adjust sump. To insure that water does not surface, it is important that the gravel bed is installed level, and that the level adjust sump is properly plumbed, After leaving the level adjust sump, the treated water will be pumped into the sand mound. These systems are designed to treat the wastewater to a level of water quality such that it meets the State of Colorado's standards for groundwater recharge. In the event that there are any questions regarding the plans and specifications, the Contractor is encouraged to call the Southwest Wetlands Group, Inc. at: TEL: 505-988-7453 Page 2 FAX: 505-988-3720 CAUTION! CAUTION! CAUTION! The plans and specifications that have been provided are unique to a particular residence. The design for the wetlands and sand mound are sized for the number of bedrooms. These two conditions may be unique to this residence. In the event that additional bedrooms are added, the wetlands and sand mound must be enlarged to accommodate the additional water. IF THESE PLANS AND SPECIFICATIONS ARE USED FOR ANOTHER RESIDENCE THE SYSTEM MAY FAIL. 1.0 CONSTRUCTED WETLANDS SITE WORK & GRADING 1.1 PROTECTION Provide temporary fences, barricades at open excavations, warning lights, coverings, bracing & shoring, and other protection as required to preserve existing structures, utilities, walks, pavements, and other items not indicated to be removed, and to prevent injury or damage to persons or property. Apply protection to adjacent properties as required. Comply with governing safety regulations. Restore damaged work to the condition existing prior to the start of work, unless otherwise directed. Do not interfere with normal traffic on roads, streets, walks and other adjacent occupied or used facilities. Provide alternate routes around closed or obstructed traffic ways as required by governing regulations. 1.2 EXISTING UTILITIES Locate by hand excavation and provide protection from damage. Cooperate with Owner and utility companies for maintaining services. Do not break utility connections without providing temporary services, as acceptable to the Engineer. Page 3 1.3 SITE CLEARING Remove trees, shrubs, grass, and other vegetation, improvements, or obstructions as indicated or which interfere with new construction. If not indicated to be removed, growing items shall be disturbed ' only if they are positive obstruction to contract work and the Owner has approved the removal. Strip and stockpile topsoil that will be reused in the work. Remove existing improvements, both above -grade and below -grade, to the extent indicated or as otherwise required to permit the construction. 1.4 DEMOLITION This section includes the removal and disposal of demolished materials from the site. Comply with applicable codes and ordinances concerning demolition operations. Salvage items may be removed at any time after demolition work starts; storage or sale on the site of removed items will not be permitted. Stockpile excavated materials where directed, until required for backfill and fill. Remove and dispose of material encountered to obtain required subgrade elevations, including pavement, obstructions visible on ground surface, underground structures and utilities indicated to be removed. 1.5 EXCAVATION AND FINISH GRADES Finish grades across the width and length of the basin shall be held to the following tolerances: The Constructed Wetland earthwork shall be constructed to within +/- 0.1 foot of the grades indicated on the Construction Drawings. Page 4 1 1.6 BACKFILL AND FILL Place and compact acceptable soil material in layers to required elevations. Use soil material free of clay, rock or gravel larger than 2" in any dimension, debris, vegetable matter, waste, and ' frozen materials. Fill below -grade areas and voids resulting from demolition operations. Use satisfactory soil materials, placed in 8" deep horizontal layers with each layer thoroughly compacted. Backfill excavations as promptly as work permits. Prepare ground surface to receive fill by removing vegetation, debris, unsatisfactory soil materials and obstruction. Scarify as required so that fill material will bond with existing surface. Place backfill and fill materials in layers not more than 8" in compacted depth, compacting each layer to required maximum density. Do not place materials on surfaces that are muddy, frozen, or contain ice or frost. Compaction: Compact each layer of backfill and fill soil materials and the top 12" of subgrade for structures, slabs, and pavements to 95% modified proctor density. At lawns or unpaved areas, 900 modified proctor density. Sprinkle water on surface of subgrade or layers of soil material where soil is too dry to permit compaction to required density. Remove and replace, or scarify and air dry soil material that is too wet to permit compaction to required density. Mechanical compaction equipment shall be used in all grading operations. In no case shall "water settling" or jetting be employed. Where vibratory compaction equipment is used, it shall be the contractor's responsibility to ensure that vibrations do not damage nearby buildings or other adjacent property. Grading: Grade areas indicated, including adjacent transition areas, with uniform levels of slopes between finish elevations. Shape surface of areas to within 0.10 feet above or below required subgrade elevation, compacted as required. Page 5 For each 2,500 sq. ft. or major portion thereof, 1 density test per 6" lift of fill or backfill. If no significant amount of fill, not less than 5 density tests of prepared soil base (natural soil) at representative locations. ' Maintenance: Repair and re-establish grades in settled, eroded, rutted, or otherwise damaged areas. In damaged compacted areas, scarify the surface, reshape and compact to required density prior to further construction. Disposal: Remove excess excavated material, trash, debris, and waste material from the site promptly. 2.0 LINERS 2.05 GENERAL Unless otherwise specified, the Constructed Wetlands portion of this work shall have a waterproof membrane under the gravel bed. The purpose of this liner is to protect groundwater from contamination by untreated wastewater. The Contractor shall therefore exercise due care in ensuring that this liner is watertight. All rips, tears, and punctures must be repaired prior to placement of gravel. If equipment is used to place gravel, the equipment must be driven over a previously placed bed of gravel at least 6 inches thick. 2.1 MATERIALS Acceptable materials include polyvinylchloride (PVC), high density polyethylene (HDPE), polyolefin (four layer composite laminate of three layer co -extruded film), bentonite or other materials such as hypalon. The liner thickness and material shall be that which is specified on the Construction Drawings. The membrane shall be sunlight and weather resistant and free of pinholes, blisters or other defects. Materials used must be high quality new compounds specifically compounded for use in hydraulic structures. Page 6 Polyolefin liners shall be those supplied by Reef Industries, Inc., Houston, TX 77275-0245, 1-800-231-2417 or an approved equal. PVC liners shall be those supplied by The Snow Company, POB 90670 Albuquerque, NM 87199, 505-345-3225. 2.2 PLACEMENT OF THE LINER PLACEMENT OF THE LINER SHALL BE PER THE MANUFACTURER'S SPECIFICATIONS, AND IN NO EVENT SHALL THE LINER BE PLACED OVER ROCKS OR OTHER MATERIALS WHICH ARE CAPABLE OF PERFORATING THE LINER. THE GROUND SURFACE SHALL BE FREE OF ALL ORGANIC DEBRIS PRIOR TO PLACEMENT OF THE LINER. THE FINISHED AND COMPACTED SUBGRADE MUST BE INSPECTED BY THE ENGINEER OR OWNER'S REPRESENTATIVE PRIOR TO THE PLACEMENT OF THE LINER. THE QUALIFIED LINER INSTALLER MUST ALSO INSPECT THE PREPARED SUBGRADE, AND PROVIDE THE CONTRACTOR WRITTEN NOTICE OF ACCEPTANCE. In the event that the liner is placed in rocky soils or on a subgrade capable of puncturing the liner, a 3 -inch bed of coarse sand and geotextile approved by the Engineer shall be placed over the soils as an underlayment. The requirement for the placement of the sand layer or geotextile shall be the responsibility of the Project Engineer or other responsible agent for the owner. Liners must have all visible surfaces covered with appropriate materials to prevent ultra -violet damage unless the material specified and supplied is UV resistant. All penetrations through the liner shall be sealed with the appropriate size boot. The liner manufacturer's materials are to be used and the specifications for installation are to be followed. Page 7 Field lap joints shall be formed by lapping the edges of the panels a minimum of six inches. All joints shall be cleaned and be free of dirt, grease, moisture or solvents prior to the application of adhesives. The joint shall be primed with a solution recommended by the manufacturer prior to the application of adhesives. 2.3 QUALIFICATIONS OF THE INSTALLER The Contractor shall hire a qualified installer who has installed a minimum of 2,000,000 sq. ft. of the specified material or who has been qualified by the liner manufacturer. The Contractor shall provided two (2) copies of the installer's qualifications prior to start of construction. 3.0 PLASTIC PIPE 3.1 MATERIALS PVC pipe shall be Schedule 40 or Class 160. Smooth -wall, corrugated, semi-rigid polyethylene pipe meeting ASTM F 405 and AASHTO M 252 and M 294 is acceptable. Perforated pipe and tubing shall be Schedule 20 PVC or High Density Polyethylene (HDPE) shall have 1/2 -inch diameter drilled holes (Mfg. by Hancor or equal, AASHTO M 252 ).

Other manufacturers may be acceptable. Submittals and independent testing reports and shop drawings shall be supplied to project manager for approval of acceptable alternates. 3.2 INSTALLATION OF PIPING All joints shall be clean and free of dirt and grease prior to _ cementing with appropriate cements. All connections (except perforated pipe) shall be tested prior to burial or operations using air or water to a minimum pressure level of 40 psi. Plastic piping subject to burial and backfill shall be protected from breakage or puncture by insuring that large rocks or other objects capable of breaking or puncturing the pipe do not come in contact with the pipe. Piping should be bedded in the trench to insure a uniform hydraulic gradient. When placing perforated piping at the influent end of an Constructed Wetland, particular care should be given to laying the piping level over its entire length. Fittings, connectors, converters, sleeves, transition pieces, couplings, end caps, or other appurtenances necessary to affect a neat and workable system shall be installed. 4.0 GRAVEL AND GRAVEL SANDS FOR CONSTRUCTED WETLANDS Gravels and gravel sands used in Constructed Wetlands shall be defined by their ability to pass a given sieve size. Gravels must be of a minimum Mohs hardness of 6. Use gravels that are suitable for use in concrete. Most gravel pits will generally have gravel that is suitable for use in constructed wetlands and will meet the following specifications: Range of Materials: 3/8" Pea gravel - 3/8" pea gravel shall meet ASTM #8 size specification with the additional requirement that 40% of the gravel shall be retained by the 1/4" sieve; and a maximum of 4% passing the #10 sieve. 1/2"-1" Gravel - 1/2" to 1" gravel shall meet ASTM #67 size specification with the additional requirement that 90% of the gravel shall be retained by the 1/2" sieve; and a maximum of 5% passing the #8 sieve. 2" - 411 Rock - 100% will pass through a 4" sieve and 98% will be retained by a 2" sieve. Page 9 It shall be the responsibility of the Contractor to insure that the materials used meet the above specifications. Materials delivered to the site MUST be 94% free of material smaller than #10 sieve. Gravels used for leach fields or concrete mixes will generally be acceptable. Submit standard sieve analysis from supplier for approval by the Engineer. If the Contractor experiences difficulty in providing suitable materials, the Engineer will consider alternatives. The intent of this site screening is to provide a gravel substrate suitable for planting cattails, bulrushes, and reeds. 5.0 PLANT MATERIALS FOR CONSTRUCTED WETLAND 5.1 ACCEPTABLE PLANTS The rooted plants (cuttings) that shall be used in Constructed Wetlands are specified below: Cattails (Typha latifolia) Bulrush (Scirpus validus) Common reed (Phragmites communis). Contractor shall plant equal portions of each species. 5.2 PLANT SUPPLIERS Plants used for constructed wetlands should be obtained from local sources if possible or from the following suppliers: J.F. New and Associates 708 Roosevelt Road Walkerton, IN 46574 21.9-586-3400 Aquatic and Wetlands Consultants 2060 Broadway, Suite 255 Boulder, Colorado 80302 303-442-5770 Page 10 5.3 CONDITION OF PLANTS PRIOR TO PLANTING All plants shall be delivered free of diseases and molds with the roots kept in a moist condition. Roots must not be allowed to dry out during planting. If plants must be stored, they should be covered with wet burlap or straw and kept from freezing. 5.4 DEPTH OF PLANTING Plants should be inserted into the gravel bed to a depth of two to four inches with the shoots slightly exposed. Roots must be placed in water. 5.5 PLANTING INSTRUCTIONS The Contractor shall use qualified workmen who are experienced with commercial landscaping work or preferably have previously planted Constructed Wetlands. The Contractor shall schedule the planting work such that it will be completed six weeks prior to the expected date that the buildings will be available for occupancy. Plants shall be set into the gravel bed 18" between the rows and 18" within the row. The rows shall be planted at right angles to the direction of flow. The odd numbered rows shall start with the first plant planted in the gravel 9" from the edge. Even numbered rows shall start with the first plant planted 18" from the edge. The plant roots should be dipped in a solution of rooting hormones prior to setting out in the gravel bed. Under no circumstances should planting be done when the air temperature is below freezing. Planting should be accomplished when the air temperature is 32 degrees F and rising or 40 degrees F. Planting should be completed by October 15 to achieve the best performance. R If after six weeks the plants for whatever reason do not seem to be taking hold and growing the owner shall contact the engineer. Re planting following these specifications shall be completed in- between the plants from the first planting. Page 11 After planting, the gravel bed shall be seeded with one of the following grasses: Winter wheat 1/2 lb. per 1000 sf. or Winter rye 1/2 lb. per 1000 sf. If planting cannot take place earlier than six weeks before the expected date of the first hard frost, than the Contractor should postpone planting until spring. If planting is postponed, then the gravel bead shall be seeded with winter wheat or winter rye and mulched as specified in this section. 5.6 MULCH After seeding, the plants should be covered with a straw mulch six inches deep spread uniformly over the gravel bed. The mulch shall be covered by a woven (not heat -bonded, extruded plastic) biodegradable netting or jute to hold the straw in place. Netting will be secured 15 to 20 feet on center or as needed to maintain mulch position on top of the gravel. Netting should have a 3/4" to 2" dimensioned grid, green or brown biodegradable material. Crossing threads must be unattached, to allow plants to expand at the base as they grow. Acceptable materials are available from: Bowman Const. Supply Belton Industries, Inc. 2310 South Syracuse Way 8613 Roswell Rd. Denver, CO 80231 Atlanta, Georgia 30350 800-666-4050 800-225-4099 5.7 WATERING AND FERTILIZING PLANTS In the event that the marsh plants are set out in the gravel bed prior to the availability of wastewater effluent, the gravel bed must be flooded to a depth such that the water level is at the top of the gravel or within 1-2 inches. A solution of commercially available water soluble plant fertilizers such as Sea Crop or approved equal, should be applied at the manufacturer's suggested rate of application every two weeks until such time as the wastewater effluent is available for filling the marsh gravel beds. Page 12 The minimum period for watering and fertilizing the plants should be six (6) weeks. Watering may be accomplished by leaving the building water supply on and running faucets continuously or by inserting a hose into the front end of the Marsh. Note: The water level must be maintained at all times at 1-2 inches below the surface of the gravel for at least one full growing season. Failure to do so will result in the death of the plants and the requirement to replant. 5.8 PLANT SURVIVAL, PROPAGATION, AND REMEDIAL PLANTING The Contractor is responsible for ensuring the survival and propagation of the planted vegetation in the wetland cells. No areas initially vegetated by the Contractor greater than 600 ft2 shall be void of vigorously growing, deliberately planted vegetation. The Contractor shall be responsible for a minimum plant survival of 80 percent of the total number of units planted. Plant survival will be based on the number of plant units that are viable and show vigorous growth versus the total number of units planted. Wetland plant survival shall be determined by the Contractor and approved by the Engineer at the following times: * Two months after the completion of initial planting in the wetland cells, (With this report the Contractor shall report to the Engineer the approximate total construction cost for each treatment wetland from the Flow Splitter to the Level Adjust Sump). * Two months after any remedial planting, and * One month prior to the Contractor's expected date of completion of all facility improvements and potential final project acceptance by the Owner. Page 13 If fewer than 80 percent of all units planted are determined to be vigorously growing and viable at any time, the Contractor shall replace the total number of units deemed to be non-viable at Contractor's own expense. The Contractor shall propose remedial _ planting locations which shall be approved by the Engineer prior to replanting activities. Remedial planting, if necessary, shall be completed within one month of wetland plant survival determination. The Contractor shall utilize desirable, viable plants for remedial planting. 6.0 ELEVATED SAND MOUNDS 6.1 General An elevated sand mound is an alternative system for the on-site disposal and treatment of wastewater. The filtering action of the sand and the associated bacteria provide additional treatment and thus allow the treated wastewater to percolate into soils that are otherwise unsuited for conventional disposal fields. 6.2 Materials Acceptable materials include: Coarse Aggregate - 1/2" - 1" (Section 02599) Medium Sand- DOT #23 Medium Sand Distribution Piping -PVC Schedule, ASTM D-1785 (Section 02622) Filter Fabric -polypropylene fabric, 3 oz/sq. yd. (Section 02271) 6.3 Preparation of the Site UNDER NO CIRCUMSTANCES SHOULD THE SOIL AT THE SITE BE COMPACTED. ALL VEHICULAR TRAFFIC SHOULD BE PREVENTED FROM HAVING ANY ACCESS TO THE AREA. The site should be mowed and all excess vegetation should be removed. Trees should be cut to ground level. Page 14 The soil in the basal area (see drawings) must be tested for wetness before tilling. If the soil sample will form a 1/8" diameter ribbon when rolled between the palms, the soil is too wet. If it crumbles, tilling may proceed. If the soil is powdery, it is too dry and should be carefully wetted with sprinkling equipment and let dry to the proper consistency. 6.4 Installation The force main and riser pipe to serve the manifold should be installed at the site prior to tilling. The backfill around the force main should be compacted slightly, enough to minimize seepage in the force main trench. The riser pipe should extend well above the ground and be marked with construction flagging to insure visibility. The basal area should be tilled seven ( 7 ) to eight ( 8 ) inches deep, (see drawing) parallel to the contours using a moldboard or preferably a chisel plow. Each furrow slice should be thrown uphill. If a chisel plow is used, then two passes should be made. DO NOT DAMAGE THE RISER PIPE DURING TILLING. Sand should be placed over the tilled area starting at the upslope edge. Sand should be placed as tilling is completed using a track - type tractor with blade. Tractor should be placing sand by pushing at least six (6) inches of sand under track to minimize compaction of soil. Placement of sand should continue until the proper elevation is reached for the top of the gravel adsorption bed. Shape a depression in the sand for the gravel bed so that there is at least twelve (12) inches of sand around the perimeter of the gravel bed. Place aggregate to a minimum of six (6) inches. Connect the manifold piping (see drawings) to the riser. All manifold piping should be level. Cover piping with an additional two (2) inches of aggregate. Place a synthetic filter (see Specifications -Section 02271) fabric over the aggregate as a barrier to the intrusion of soil. Page 15 Cover the entire mound with at least six (6) inches of clay soil, mounding the clay soil at least twelve (12) inches at the top of the mound to promote good drainage. Place six (6) inches of good soil over the mound and seed with Andropogon scoparius (Little Bluestem) native grass. 7.0 LEVEL ADJUSTING BASIN OR SUMP 7.1 MATERIALS Water level of the constructed wetland shall be adjusted by manually removing and inserting the desired lengths of three (3) inch PVC pipe in the slip -joint (socket) elbow located in the bottom of the level adjusting basin as shown on the drawings. The basins shall be a 24 -inch diameter, ribbed PVC sump provided with height as shown on the drawings. Inlet and outlet gaskets shall be provided with the basin at sizes shown on the drawings. Basin height shall extend a minimum of two (2) inches above grade. Basin shall be covered with a lid insulated with two (2) inches of rigid, closed -cell polystyrene foam and secured with tamper- resistant stainless steel bolts. It shall be that provided by Orenco Systems, Inc. 22826 Colonial Rd., Roseburg, OR 97470, 503-673-0165. Other manufacturers may be acceptable. Submittals and independent testing reports and shop drawings shall be supplied to Project Manager for approval of acceptable alternates. 7.2 INSTALLATION Basins shall be installed plumb and level in accordance with the construction drawings. Page 16 8.0 NATIVE GRASS SEEDING . 8.1 QUALIFICATIONS All work specified herein shall be performed by a licensed contractor experienced with the type and scale of work required, which includes having equipment and personnel adequate to perform the work satisfactorily. 8.2 COORDINATION Determine the acceptability of subgrade preparation prior to the start of native seeding operations. Protect all existing items to remain and new work of other trades to ensure proper timing of each phase of work. 8.3 DELIVERY, STORAGE AND HANDLING Packaged Materials: Deliver packaged materials in containers showing weight, analysis and name of manufacturer. Protect materials from deterioration during delivery, and while stored at site. Excavation: When conditions detrimental to seed growth are encountered, such as rubble fill, adverse drainage conditions, or obstructions, notify Engineer before seeding. 8.4 SEED All native grass seed shall be obtained from sources in Colorado unless proof is provided that a particular seed is unavailable within the state. 8.5 MULCH Mulch to be applied over seeded areas shall be virgin wood cellulose fiber, clean hay, or other approved material enough to cover 900 of the seeded surface at a depth of two (2) inches. Page 17 8.6 BINDER Natural binder made from the seed coat of plantain. M-51 Binder available from Plants of the Southwest, Santa Fe, NM or approved equal. Apply 41 lbs. per 1,000 square feet over mulch. 8.7 SOIL AMENDMENT MATERIALS Soil Amendment Material shall be composted sawdust/manure. Apply at rate of 6 cubic yards/1,000 square feet, or approximately 2" layer. Preparation of the Seed Bed: on level areas and newly graded areas. The seed bed shall be prepared to a minimum depth of four (4) inches by tilling with a disc harrow or chiseling tool. All competitive vegetation shall be uprooted during seed bed preparation and the soil shall be uniformly worked to a smooth surface free of clods, large stones of over two (2) inches in any dimension, or other foreign material that would interfere with seeding equipment. Tilling will not be required on ground which is already loose to a depth of two (2) inches or more which has undergone regrading and fill. All newly cut slopes will require tilling. All tillage must be performed across the slope when practical and shall be performed in two directions whenever one pass is insufficient to adequately break up the soil in the Engineer's opinion. No work shall be done when the moisture content of the soil is unfavorable or the ground is otherwise in a non -tillable condition. Tilling shall not occur when wind speeds are over 10 MPH or will cause dust problems for adjoining areas. The extent of seed bed preparation shall not exceed the area on which the entire seeding operation can be accomplished within a 24- hour period. Page 18 Amendment material: Spread 2" layer of soil amendment material over areas to be seeded Mix into top 4 inches of existing soil. Rake smooth and remove debris, and stones over 1" in any dimension. Repair Seed Bed: If prior to seeding the Engineer determines that rain or some other factor has affected the prepared surfaces and that it may prevent seeding to the proper depth, the Contractor shall again prepare the seed bed. 8.9 SEEDING General: Do not use wet seed or seed which is moldy or otherwise damaged in transit or storage. Do not sow less than the quantity of seed specified or scheduled. Do not seed when wind is greater than five miles per hour. Seeding Dates: Shall be accomplished between May 15th and August 6th unless specific permission in writing is issued by the Engineer to allow seeding before or after these dates. It is recommended than an annual winter grass be planted to keep the site free of weeds until spring if these dates cannot be made and demolition has occurred. Broadcast Seeding: The seed shall be mechanically broadcast by use of a rotary spreader or a seeder box with a gear feed mechanism or hand spread. If hand spread, use broad sweeping motion of the arm. Seed over the entire seeding area in two directions, i.e., north/south first, then east/west. Immediately following the seeding operation, all the seeded areas shall be lightly raked to provide approximately 1/2 inch of soil cover over most of the seed without damaging the existing grass stand. Contractor's vehicles and other equipment are prohibited from traveling over the seeded areas. Binder: Uniformly apply binder over mulch at specified rate and water in. Page 19 8.10 WATERING The Contractor shall provide water to distribute uniform coverage to previously seeded and mulched areas one time only. + 8.11 MAINTENANCE Contractor shall keep all native grass areas free of weeds until acceptance by the Owner. 8.12 CLEANUP AND PROTECTION Protect work and materials from damage due to seeding operations by other contractors and trades and trespassers. Maintain protection during installation and maintenance periods. Treat, repair or replace damaged work as directed. 8.13 INSPECTION AND ACCEPTANCE (Optional Services) When work is completed, including watering, Engineer, upon request, will make an inspection to determine acceptability. Where inspected seeding work does not comply with requirements, replace rejected work and continue specified maintenance until reinspected by Engineer and found to be acceptable. 9.0 SEPTIC TANK 9.05 PRELIMINARY INSPECTION OF EXISTING SEPTIC TANKS (This subsection applies if the owner is using an existing septic tank.) Prior to start of construction, the Contractor shall make a visual inspection of the existing septic tanks. The Contractor, upon completion of said inspection, shall warrant in writing that the septic tanks are in sound condition, have at least two compartments, that inlet and outlet piping is in good repair and not leaking, and that the net useable capacity of the tank is at least 1000 gallons. E S T In the event that the above conditions are not met, the Contractor shall immediately notify the Engineer in writing. In the event that the septic tank is not suitable, the following septic tank specifications shall govern the installation of any new tanks. 9.1 MATERIALS Materials shall be polyethylene, reinforced concrete or fibergla approved for installation by Be n i i i o r__ � nty an -tb-e ct-at of Iiew Mem-capable of withstanding lateral pressures for intermittent periods between pump -out and liquid filling. The septic tank should contain an internal baffle and connecting tees accessible by surface access risers. The pipe connections through the tank walls shall be a gasketed watertight connection capable of accepting Schedule 40 PVC pipe. The tanks shall be fitted with covered risers extending four inches above finished grade. Please refer to the detail drawing for design recommendations on concrete tanks. 9.2 INSTALLATION The Septic Tank shall be set plumb and level in a bed of sand or gravel according to the manufacturer's specifications. In the event fiberglass or polyethylene tanks are used, care should be taken by the contractor to ensure that the initial backfill sand or gravel flows evenly under the haunches of the tank. The select aggregate shall be placed to a height 4-6 inches above the midline of the tank. Native soil may be used for the final backfill. If polyethylene or fiberglass tanks are used, then stones larger than three inches should be removed from backfill.
