D. PRESENTATIONS/ANNOUNCEMENTS: None
E. PUBLIC COMMENT:

Karl Kelzer, 706 Foothill Blvd. commented that shortly after I moved into my property and I discovered there were issues with the home and flooding on my property. I have contacted the City and the Building Inspector did come out but his information was unacceptable. I have contacted the developer and was told it was signed off and to "pound sand". I would appreciate a follow up with the City.

Patrice Prest asked when the apartment complex on Waterman Road will be on the agenda-Council will let her know when it will be agendized. Ms. Prest commented that she was told that the Castle Oaks Landscape issue would be on this agenda and it is not.

Council member Wratten asked that we try to get this item on the agenda before the end of August.

Larry Rhoades commented that when the 276-unit apartments on Waterman Road is on the agenda, I would like the Police Department to pull the records from when they built the prison and how many calls they had from the apartments near the Elementary School the first year over the year before.
#1
Tom Quinn commented on the condition of the City at the different entrances into the City, the issues at his neighbor's home and term limits on elected officials.

Patti Fisher-Misuraca asked the Council how can we keep the City involved to help the citizens move forward to try to save the schools in lone. My gut tells me that once they take lone Elementary, they will take our old school at lone Junior High School-the oldest school in Amador County. I don't think they have followed a number of rules when they close a school and they have not looked at the proximity of the railroad to the school. Michael Rock reminded the Council has a Closed Session tonight and you may want to decide whether to agendize this issue after the Closed Session.

Gary Thomas suggested a Committee be appointed to look at the different issues related to consolidation.

F. CONSENT CALENDAR:

4. Approval of a Lease Agreement with Sang Hai Corp. (Castle Oaks) for the Operation of an Electric Sign Board on City Property- Michael Rock explained that the Planning Commission adopted Resolution No. 2021-03, approving the Site Plan review for the Castle Oaks Entry Sign at 1000 Castle Oaks Drive. The staff report in part stated: "The Castle Oaks Entry sign will be a placement of one (1) freestanding pylon sign with an electric message display board at 1000 Castle Oaks Drive, at the entryway to Castle Oaks Golf Club and residential development. This project was previously approved at a different location on the existing site. The proposed sign is 93.65 square feet in size and 18 feet in height. This project will require approval of a Caltrans permit. The agreement stipulates the City will receive revenue sharing of 15% of gross revenues per year.

Estimated revenue to the City based on gross revenue of $60,000/year is $9,000/year This agreement has been reviewed with George Lee, General Manager of Castle Oaks Golf Course and negotiated the Revenue Sharing Agreement.

Councilmember Rhoades commented that the lone Municipal Code Section 17.44 Signs on City property does not allow private party signs on City properties. From what I see, we cannot do this and need to change our Municipal Code.

Michael Rock stated that this property is not considered a City facility and is just a sliver of right-of-way and the Golf Course already has a lease with the City. City Attorney, Carolyn Walker commented that under normal terms, this is not a public facility and would not include all property.

After discussion by Council, it was moved by Vice Mayor Plamondon, seconded by Councilmember Wratten and carried to approve the Lease Agreement with Sang Hai Corp. Councilmember Wratten asked how the revenue is going to be generated and that the agreement be revisited every five year.

Recently the City's website host performed a routine update that rendered the City's website nearly non-functional. Staff is no longer able to edit pages, upload content on the majority of web pages or utilize most features on the website. At this time, staff is only able to upload meeting agenda packets. Redesigning the website offers a unique opportunity to add important information and capabilities missing from the current website.

D. PRESENTATIONS/ANNOUNCEMENTS:

Annual Report from Amador Water Agency by Mr. Larry McKenny, General Manager:
• We are adhering to the State's restrictions-20% reduction--regarding the drought and have sustained the Stage 1 Water Alert-limit watering their turf outside to two days a week and not letting hoses run down the gutters, letting your hose run while washing your car and identifying leaks
• Our water supply in Amador County is relatively solid compared to other agencies in the State
• Our real problem is our infrastructure and the five treatment plants. The treatment plant in lone is quite old and it has not been kept up in terms of investments to meet current demand, which triggered our Water Master Plan Study. • The Tanner Plant and the lone Plant run at full capacity in the summer months. We looked at the Water Plants to see if there were measures we can do option that we can take to expand or extend the capacity. There are some things we can do-at the lone Plant we are to replace the cover on the treated water clear well and will extend the life at least eight years. We are looking at replacing the clarifier and doing a geotechnical investigation of the site-whether to expand on that site or building a new site at Sutter Hill to serve the whole region. • Be mindful that every drop counts!
E. PUBLIC COMMENT:

Paul Perotti, President of the Castle Oaks Senior Men's Club shared his concern, frustration and anger over the reoccurring problems over the years of availability of water at the Golf Course. Our main goal tonight is to bring about an outcome that effectively initiates the will of this Council to lead a process that permanently solves the problem. If there is a willthere is a way. You must demand that all individuals, agencies, cities and others involved in the decision related to the flow of wastewater in the county hammer out an agreement before our Golf Course is permanently damaged. Stop the blame game, rise to the occasion and do your job and move full steam ahead with the interconnection project.

Elmer Rhode, member of the Castle Oaks Senior Men's Club addressed the City's lack of action with regards to irrigation water to the golf course. In 2017 a letter was sent from the City to ARSA, Dan and Dominic were on the Council. According to the Ledger Dispatch this was just a ploy to get a better deal from ARSA. If the article was true, ARSA called your bluff. The City had five years to resolve a way to irrigate the golf course without ARSA and what did you do-nothing until May 18, 2021 when an RFP for the headworks replacement and the interconnection project with the wastewater and tertiary plants was released.

Proposals were due June 17, 2021. A contract for the project was signed in December 7, 2021. Everything has slipped 6 months. The course will probably needs to be reseeded, which will be the responsibility of the City.

Kim Smith, member of the Castle Oaks Senior Men's Club- have played regularly at Castle Oaks since 2003. The course now looks more like a desert than the course I have enjoyed playing for almost 2 decades. Most of the grass is either dead or dying. Playing conditions are poor at best and only will get worse as we get in the hotter weather. The golf course is an asset not only to the City but to the County and has been here over 30 years. The time has come for all stakeholders to pull together toward a common goal to provide the golf course with a reliable source of irrigation water. Litigation should be a last resort.

Allen Beers, Sutter Creek and member of the Castle Oaks Senior Men's Club. More than 30 years ago ARSA and the City of lone entered into an agreement that allowed affluent from the sewer treatment plant in Sutter Creek to be disbursed onto the Golf Course. Early in the 2000's Sutter Creek began negotiations with Gold Rush Ranch with plans to build a golf course, hotel, homes and a golf course with plans to upgrade the treatment plant and to disburse the affluent onto the golf course. ARSA then sent a 5-year notice to the City that they will no longer send their affluent to lone. In 2010, there was lawsuit against Sutter Creek and Gold Rush indirectly in 2010, which was not settled until 2016, and the developer had shut down. ARSA had a continuing need to send their affluent to lone and arrangements were made to continue the contract. Since that time lone has had issues with the affluent from Mule Creek State Prison. The current contract with ARSA will end at the end of July and because of the timeline of the interconnection project, it will not save the golf course because of a variety of issues that have not been resolved.

Kip Garvey, in reviewing the history of ARSA and the City, which most has been reviewed with you tonight-in 2011 something happened with the City and the City Council recognized that there was a situation where the water at the golf course was in jeopardy.

They came up with a plan and notified ARSA that they may not be renewing their contract. They could not have done that unless they had a plan, which I think was the interconnection project. Why hasn't this interconnection project completed? We are asking the City Council help and cooperation in expediting a permanent solution and move the interconnection project to the front burner.

Meredith Anderson, Sierra Business Council runs the energy watch program under PG&E. Ms. Anderson explained the services available through the Sierra Business Council-be your energy manager, free technical services, Green Gas Program, and make sure you are getting the best services and energy savings. Ms. Anderson provided her contact information for staff.

Karl Kelzer, 706 Foothill Blvd. has had problems with his property for the last two years and has had no cooperation from the City. He would like someone who is certified do an inspection on his property and get to the bottom of what is going on. He also asked to set up a meeting with the Mayor. The waste material that was dumped on the track at Howard Park is very difficult to walk on and it is just a matter of time until some elderly person falls and breaks a hip and what a disgrace it is to the Park itself.

Larry Rhoades commented that there was a well at the Sewer Plant providing 800 gallons per minute and ran the Preston Farmland since the 1930's and this City disconnected it. I don't know why it is not being used.

Bette Rhoades read a letter into the record concerning the discussion on the sign at the Castle Oaks Golf Course at the June 7, 2022 meeting. When Councilmember Rhoades informed the Council of the Sign Ordinance in the lone Municipal Code-Signs on City Property--immediately, Michael Rock berated Councilmember Rhoades for not contacting him first before bringing it up at the meeting and it was only done to embarrass staff. It is not the Councilmember's duties to tell the manager everything some of his constituents have the same concern--that is why there is a Council meeting.

Yes, I am upset on the way your treat him, as his Mother and as a concerned citizen.

Dave Livingstone commented on the issues about water in the City of lone-not a resident of Castle Oaks. I am concerned about any building permit given to any developer for housing or commercial. We were asked by the General Manager of the Amador Water Agency to cut our usage of water and if we can't with the existing residents use the amount of water we need and have been asked to cut back why would the City Council consider issuing more building permits for more buildings.

IONE, CA 95640

1.0 INTRODUCTION
This groundwater monitoring report describes the results of the Second Quarter 2022 Groundwater Monitoring event conducted at the Castle Oaks Golf Course (COGC) in Ione, CA on June 12
th and 15th
, 2022. This Report has been prepared to satisfy reporting requirements in the Revised Monitoring and Reporting Program (MRP) No. 93-240 dated April 17, 2001. The MRP was developed to monitor compliance with Water Reclamation Requirements (WRR) Order No. 93-240. The WRR prohibits the degradation of any water supply resulting from the discharge of tertiary water at the COGC. This Report has been submitted to the City of Ione (City) for review and comment and is submitted by EcoUrban Associates (EUA) to the California Regional Water Quality Control Board, Central Valley Region (Regional Board) on the City’s behalf.

2.0 SITE DESCRIPTION
The COGC is located in Ione Valley approximately one mile northwest of Ione. The Mule Creek State Prison Wastewater Treatment Plant and disposal spray fields are located upgradient (northeast) from the site and the City Tertiary Treatment Plant (Treatment Plant) is located downgradient (southwest) of the COGC. A Vicinity Map is shown on Figure 1. The Treatment Plant water is treated to Title 22 standards and pumped to storage ponds on the COGC for seasonal irrigation. Mule Creek flows through the site from north to south, then east to west. Sutter Creek forms the south boundary of the COGC.

The COGC topography slopes toward the southwest and elevations range from 260 to 300 feet above mean sea level. Three groundwater wells at the COGC monitor for impacts to the beneficial uses of the groundwater. Well CO MW-1 is located in the upgradient area (northeast) and CO MW-2 and CO MW-3 are located in the downgradient area (southwest). In addition to the monitoring wells, depth-to-water measurements are collected from piezometers CO P-1, CO P-2, and CO P-4 located west of the Treatment Plant and from wells and piezometers at the City Wastewater Treatment Plant (WWTP) south of Sutter Creek. A map showing the well locations in provided as Figure 2. COGC - 2 -
groundwater elevation data are combined with data from the WWTP and displayed on the Potentiometric Surface Map on Figure 3.

EUA personnel performed groundwater monitoring and sampling in COGC. The samples were delivered to Pace Analytical. within the required holding times following chain-ofcustody procedures. Field forms are provided in Attachment A and laboratory analytical results are in Attachment B.

3.0 MONITORING AND REPORTING REQUIREMENTS
The Revised MRP No. 93-240 specifies quarterly monitoring for groundwater elevations, total coliform organisms (TCO), nitrate as nitrogen (nitrate-N), ammonia as nitrogen (ammonia-N), total dissolved solids (TDS), and pH. In addition, the City monitors for dissolved oxygen (DO), oxidation reduction potential (ORP), and electrical conductivity (EC) measurements are collected at the time of sampling.

Monitoring and sampling were performed by EUA personnel trained in the operation of field-testing instruments. The field technician training includes instrument calibration in compliance with the manufacturer’s recommended procedures and frequencies.

Instrument calibration records are included on the field observation sheets in Attachment A.

4.0 FIELD OBSERVATIONS
On June 12
th and 15th
, 2022, quarterly monitoring was performed and included the collection of a depth-to-water measurements from wells using an electrical sounding tape decontaminated between uses. EUA used dedicated bailers that have been kept uncontaminated within the well casing. All wells were purged of at least three casing volumes of water using dedicated disposable bailers. Field parameters were recorded during purging using appropriate and pre-calibrated meter. Purge rates ranged from approximately 1 to 2 gallons per minute (gpm). All wells recovered immediately to at least 80 percent of the pre-purge depth to water before sampling.

No sheens or odors were observed during purging. The purge water from all three wells had slight to moderate levels of turbidity. Field parameters appeared stable at the time of sampling. Field observation sheets are in Attachment A. Field data results are summarized in Table 1 and Table 2.

6.0 DISCUSSION
In upgradient well CO MW-1, the groundwater elevation is typically highest in the first or second (and sometimes the third) quarter, and lowest in the third quarter. In downgradient wells CO MW-2 and CO MW-3, the groundwater elevation is typically highest in the first quarter and lowest in the third quarter. The groundwater elevation decreased from the previous quarter in all three monitoring wells (CO MW-1 decreased

1.02 feet; CO MW-2 decreased 0.74 feet; and CO MW-3 decreased 1.14 feet). The average groundwater elevation change was a 0.97-foot decrease. Consistent with historical measurements, the piezometric surface of the groundwater table generally slopes to the southwest at approximately 0.004-0.007 feet per foot (ft/ft). Seasonal groundwater typically fluctuates approximately 3-5 feet in site wells. Hydrographs of site wells are shown in Figure 4.

No groundwater limitations are specified in the MRP. In the absence of specified limitations, laboratory results are compared to primary and secondary maximum containment levels (MCL) for drinking water published by the Regional Board. Because high concentrations of many parameters occur naturally in groundwater at the site, an exceedance of an MCL does not necessarily indicate a degradation of background water quality. The groundwater analytical data is tabulated in Attachment A.

This quarter TCO levels were non-detect to moderate in the three wells <1.8 MPN/100mL in CO MW-1; 33 MPN/100mL in CO MW-2; and 79 MPN/100mL in CO MW-3) with MW-2 and MW-3 being above the Primary MCL (2.2 MPN/100mL). All three wells have a history of TCO detection starting in 2010 and were disinfected using chlorine in May 2013 and also in 2019, a week before the 3 rd quarter 2019 sampling
event. The intermittent detections of TCO that is most likely due to natural bacteria present in the surrounding groundwater, not merely in the well itself. These detections may be due to natural bacteria in the groundwater and are not historically considered a result of effluent discharges. Historical coliform values collected from groundwater during quarterly monitoring are graphed on Figure 5.

Nitrate-N levels were below the primary MCL of 10 milligrams per liter (mg/L) in all monitoring wells. The highest nitrate-N concentrations are at upgradient well CO MW-1 (8.0 mg/L). Upgradient sources and/or other site uses may influence nitrate-N in CO MW-1 but a watershed-wide groundwater evaluation has not been conducted.

Downgradient wells have historically shown lower detection levels near to the method practical quantitation limit (PQL). Fluctuations in nitrate-N concentrations with time are shown on Figure 6.

Levels of ammonia-N were detected at trace levels in all of the three monitoring wells this quarter (0.11 mg/L in CO MW-1; 0.11 mg/L in CO MW-2; and 0.088 mg/L in CO MW-3). All levels were well below the secondary MCL of 1.5 mg/L. Historical ammonia-N concentrations are graphed on Figure 7.
- 5 -
The TDS in CO MW-2 (870 mg/L) and MW-3 (560 mg/L) was detected at or above the 500 mg/L secondary MCL for drinking water. Well CO MW-1 was sampled below MCLs. Since monitoring began in 2002, TDS in CO MW-2 has ranged from 600 mg/L to 1,700 mg/L. Well CO MW-2 is said to have been completed in clastic sediments of the Modesto Formation. There is no indication that the source of the high TDS at CO MW-2 is from the Treatment Plant effluent. TDS in all wells were within the range of historical values. TDS:EC ratios for natural waters typically range from 0.55 to 0.75. The TDS:EC ratio ranged from 0.82 to 0.84 this quarter with an average of 0.83. Groundwater and effluent TDS values are graphed on Figure 8.

Dissolved arsenic was detected at trace to non-detectable levels in the three monitoring wells this sampling event. Testing for arsenic is not required in the MRP. Sample results were all near or below the primary MCL of 0.00038 mg/L. The fluctuations with time of arsenic are shown on Figure 9.

Dissolved manganese was detected at relatively low to trace levels in all three monitoring wells. Levels were highest in CO MW-3 (0.11 mg/L) at concentrations just above the secondary MCLs of 0.05 mg/L. MW-3, historical manganese and iron values typically exceed the secondary MCL. It is very possible that these trace-detected levels are from naturally existing conditions of the lateritic bedrock immediately west of the local groundwater table.

Dissolved iron was not detected in any wells. Dissolved iron levels from all wells were below the secondary MCL this quarter. Testing for iron and manganese is not required in the MRP. The fluctuations with time of iron and manganese in groundwater are shown on Figures 10 and 11, respectively.

Dissolved oxygen (DO) measurements were above 2.0 mg/L for monitoring well CO MW-1 (2.36 mg/L). Levels in CO MW-2 and CO MW-3 were slightly below 2.0 mg/L (1.85 mg/L and 1.92 mg/L, respectively). Site wells have been monitored for dissolved oxygen and oxidation reduction potential (ORP) since 2009. The low ORP condition (<10 mV) in groundwater in likely due to aerobic and anaerobic bacterial in the groundwater.

The field pH was measured in CO MW-1 (6.31 SU), CO MW-2 (5.52 SU) and CO MW-3 (6.21 SU). All wells were outside the secondary MCL range of 6.5 to 8.5 standard units (SU). Instrument calibration sheets are shown with the field documents in Attachment A. Values for pH in CO MW-1, CO MW-2, and CO MW-3 are shown on Figure 12. - 6 -

7.0 CONCLUSIONS
Groundwater monitoring at COGC indicates compliance with the MRP and the Standard Provisions and Reporting Requirements.

Coliform levels remain variable but consistent with natural background levels.

The nitrate-N concentrations did not exceed the water quality objective of 10 mg/L in any wells.

TDS in CO MW-2 exceeded the secondary MCL of 500 mg/L. The elevated TDS in CO MW-2 is likely not a result of TDS in the effluent tertiary-treated water applied at the COGC but instead characteristic of localized natural conditions.

Dissolved iron concentrations were not detected from any wells this quarter.

Dissolved manganese concentrations exceeded the secondary MCL levels for one of the wells (0.11m g/L in CO MW-3) analyzed this quarter. The secondary MCL is not a health-based limit and testing of the effluent for manganese is not required by the MRP.

Dissolved manganese, iron, and arsenic do not appear to be influenced by COGC discharges and are not required by the MRP.

8.0 RECOMMENDATIONS
EcoUrban Associates recommends the following:
- A reduction in sampling frequency (such as semi-annual) might be warranted given the degree of groundwater characterization that has been established from previous sampling events.

QUARTERLY MONITORING REPORT
SECOND QUARTER 2022
Order No. R5-2013-0022 (Rev.1)

CITY OF IONE
1 E. MAIN ST.

IONE, CA 95640

1.0 INTRODUCTION
This groundwater monitoring report describes the results of the second quarter 2022 groundwater monitoring and sampling activities at the City of Ione (City) Wastewater Treatment Plant (WWTP) in Ione, California. The WWTP is located approximately 1 mile west of Ione on the south bank of Sutter Creek in Section 26, T6N, R9E, Mount Diablo Baseline and Meridian, Amador County, California. A Vicinity Map is presented as Figure 1 in Appendix A. This Report is provided by EcoUrban Associates (EUA) at the request of the Ione City Manager to comply with groundwater monitoring requirements in the Revised Monitoring and Reporting Program (MRP) No. R5-2013-0022 (Rev.1) and Cease and Desist Order (CDO) R5-2014-0157, adopted December 5, 2014. All well monitoring and sampling activities were conducted on June 12
th and 15th of 2022. Groundwater elevations are
discussed in Section 5 and water quality results are summarized in Section 7 of this report.

A Site Map indicating the monitoring well locations is presented as Figure 2 in Appendix A.

Also included with this Report are field forms and laboratory analytical results. This Report was submitted to the City for review and comment and is submitted on the City’s behalf by EcoUrban to the California Central Valley Regional Water Quality Control Board (RWQCB).

2.0 SITE DESCRIPTION
The WWTP is situated in Ione Valley at the south corner of the intersection between West Marlette Street and Dave Brubeck Road (formerly Old Stockton Road). All monitoring wells are spread out across the valley and bordered to the north by Sutter Creek. The topography slopes toward the west slightly and the surrounding properties are primarily agricultural. A residential neighborhood is located adjacent to the northeast corner of the site.

2.1 Monitoring Network
The WWTP is monitored by an on-site network of nine groundwater monitoring wells and four piezometers. Each quarter, samples are collected from the nine wells and depth-towater measurements are collected from the nine on-site monitoring wells, the four piezometers, and the six offsite monitoring wells (MW-08 series).

The groundwater monitoring well network consists of the following: MW-1 and MW-1A, located east of the WWTP; wells MW-2A, installed in July 2013, and MW-2 monitor - 2 -
groundwater downgradient from percolation Pond 5; well MW-2, located between Ponds 4 and 5 and Sutter Creek; and wells MW-3, MW-3A, MW-4, MW-4A, and MW-5A monitor downgradient groundwater. The collection of surface water samples from Sutter Creek is not required by the MRP. As previously mentioned, wells P-3 and P-5B have been added for this sampling event per CDO R5-2019-0701. As of the writing of this report, these wells are not required in future sampling events. The six offsite MW-08 series wells are located east and south of the WWTP. Deep wells are herein designated “A” and shallow wells “B”.

Three inactive wells (MW-5, MW-6, and MW-7) were destroyed during the previous quarter as described in the Well Destruction Report dated August 15, 2017.

3.0 MONITORING AND REPORTING REQUIREMENTS
MRP No. R5-2013-0022 (Rev.1) specifies quarterly monitoring of the site wells. The groundwater elevation is measured at all locations, and then the wells are purged of at least three casing volumes until the pH, electrical conductivity (EC), and temperature stabilize. Temperature, pH, and EC measurements are collected during purging and at the time of sampling. The MRP specifies the quarterly analysis of groundwater samples for pH, total dissolved solids (TDS), nitrate as nitrogen (nitrate-N), ammonia as nitrogen (ammonia-N), dissolved iron, dissolved manganese, and total coliform organisms (TCO).

In addition to the quarterly analyses, the annual analyses include total nitrogen (TN), dissolved arsenic, aluminum, boron, calcium, magnesium, potassium, sodium, total alkalinity (including alkalinity series), chloride, sulfate, and hardness. These annual tests are conducted in the 4th quarter of last year.

All analytical results are compared to groundwater limitations defined in the Waste Discharge Requirements Order R5-2013-0022-001 (WDR) and the CDO. Values used in this Report are included in Table A through E within the text of this report and in Tables 1, 2, and 3 of the tables section of this report.

The CDO specifies quarterly monitoring of wells MW-2, MW-2A, MW-3, and MW-3A for pH, EC, dissolved oxygen (DO), oxidation-reduction potential (ORP), TDS, dissolved iron, and dissolved manganese. Results from these analyses are included in Appendix B of this Report.

Monitoring and sampling were performed by EcoUrban personnel who are trained in the operation of field-testing instruments and groundwater monitoring and sampling. The field technician training includes instrument calibration in compliance with the manufacturer’s recommended procedures and frequencies. Instrument calibration records are included with the field forms in Appendix A.

th and 15th of 2022, EUA performed quarterly groundwater monitoring and sampling at the WWTP. The depth to water in all WWTP monitoring wells was measured using an electrical sounding tape decontaminated between wells. All wells were purged of at least three casing volumes of water using a dedicated disposable bailer. Since dedicated bailers were used, no triple-rinse decontamination was performed for each well.

Field parameters were recorded during purging with observation and documentation regarding the groundwater drawdown and recharge in each well. Purge rates ranged from approximately 0.5 gallon per minute (gpm) to 2.5 gpm, which is consistent with historical ranges.

All monitoring wells were observed to have clear to moderate clarity. No odors or sheens were noted in the purge water. All wells were checked to ensure that at least 80 percent of the pre-purge static water level was allowed to recharge before being sampled. All purged water was discharged to the ground surface adjacent to its respective well.

All groundwater samples were placed in new, sterile laboratory-supplied sample containers supplied by the analytical laboratory, were labeled, and placed in an ice chest with ice pending same-day delivery to Pace Analytical under chain-of-custody procedures. The groundwater elevations, field parameter measurements, and groundwater chemistry are in Tables 1, 2, and 3. Field observations of the water levels in the pond are presented in the following page in Table A. Elevations are based on reported average freeboard in monthly monitoring reports prepared by the City. - 4 -

5.0 GROUNDWATER ELEVATIONS AND GRADIENT
The depth to water in wells associated with the WWTP ranged from 4.80 feet in MW-08-1 to 21.52 feet in MW-3A. Depth-to-water measurements are used to calculate groundwater elevation. Measured depth to water is typically lowest (highest groundwater elevation) in first quarter and highest (lowest groundwater elevation) in third quarter.

Compared to the previous quarter, the groundwater elevations in all wells decreased an average of 1.04 feet with 15 wells showing a decrease in water elevations. The greatest increase in groundwater elevation was a 0.71-foot increase at P-2; the greatest decrease in groundwater elevation was a 3.58-foot decrease at MW8-2B. Hydrographs of the site groundwater elevation data are shown in Figure 4.

The groundwater gradient upstream and downstream from the WWTP and adjacent to Sutter Creek is down-valley (west) and parallel to Sutter Creek. Historically, various groundwater mounds or domes have been observed under the WWTF which may be caused by the abrupt curvature of Sutter Creek in the northwestern part of the WWTF and other potential factors like ground infiltration in the eastern part of the WWTF property or potential gravel channels in the northwestern part. The mound results in a relatively flat gradient [approximately 0.002 feet per foot (ft/ft)] between MW-1A and MW-1 east of the ponds and relatively steep gradient (approx. 0.006 ft/ft) along the southern part of the property. The average down-valley gradient is approximately 0.0055 ft/ft. A map of the estimated potentiometric surface is shown in Figure 3.

6.0 LABORATORY ANALYTICAL RESULTS
Groundwater samples collected this quarter were analyzed by Pace Analytical in Bakersfield, California. The laboratory data from this quarter along with the CDO required data are summarized in Table 2. The complete historical data set for the active groundwater monitoring wells are tabulated in Tables 1, 2 and 3. Existing California primary and secondary Drinking Water Maximum Contaminant Levels (MCLs) are included in the tables and constituents occurring in concentrations greater than the MCLs are highlighted in yellow. In addition, TDS is compared to the Water Quality Goal (WQG) for Agricultural Use Protective Limits specified by the State Water Resources Control Board. Laboratory estimated values occurring below the Practical Quantitation Limits (PQL) and above the Method Detection Limit (MDL) are highlighted in blue. Laboratory certificates of analyses, quality control records, and chain-of-custody records are included in Appendix B.

7.0 DISCUSSION

7.1 Groundwater Elevation
The groundwater gradient indicates a west-southwest groundwater flow direction with a slope of approximately 0.0055 ft/ft. As usual, groundwater elevations remain at levels highest in the first quarter and lowest in the third. Mounding appears to be present in the northern and southeastern parts of the WWTF, as referenced above. Groundwater gradient directions and magnitudes this quarter are generally consistent with historical ranges.

7.2 Water Quality
Below is a description of the analytes that were tested this quarter as required for quarterly and annual monitoring as compared to MCLs.

Groundwater limitations for TCO and Title 22 constituents are specified in the WDR. The TCO limitation is 2.2 most probable number per milliliter (MPN/100 ml) as a 7-day median.

For Title 22 constituents, laboratory results are compared to primary and secondary drinking water MCLs published by the Regional Board. TCO was detected above the MCL (2.2 MPN/100 ml) in five of the nine wells sampled. TCO was not tested from well MW-3A due to a missing sample container. Various wells have had sporadic TCO detection in the past with higher levels being detected more frequently in the wet season.

It should be noted that detectable levels and levels over the TCO limitation continue to be observed in wells MW-1 and MW-1A, which indicates that sources of bacteria may also be from upgradient sources besides the WWTF.

Site pH results were within the agricultural beneficial use (WQO) of 6.5 standard units (SU) to 8.4 SU for five of the nine monitoring wells this quarter. The results for this event - 6 -
are within historic ranges and natural ranges for most natural groundwater within the U.S. 1 Nitrate-N concentrations in all groundwater samples were below the drinking water primary MCL of 10 milligrams per liter (mg/L). Nitrate-N concentrations appear to have normalized below MCLs since 2016. Temporal changes in groundwater nitrate-N are shown in Figure 6.

Total nitrogen (TN) can be a preferred parameter when evaluating nitrogen impacts from wastewater treatment plants because it includes the sum of nitrate-N and total Kjedahl nitrogen (TKN), including ammonia-N. Nitrogen can convert to any of these forms depending on redox conditions and biological activity in soil. Although there is no numeric groundwater limitation for total nitrogen, the MCL for nitrate-N was applied. The highest TN concentration detected was from Well MW-3A which was detected a total nitrogen of

4.4 mg/L. Total nitrogen in groundwater and historical effluent are plotted in Figure 7.

Ammonia-N was detected above the taste and odor threshold of 1.5 mg/L in MW-1A, MW-2, MW-2A, MW-3, and MW-3A. The highest detection of nitrogen was found in the form of ammonia-N and was observed at wells MW-3A (4.4 mg/L ammonia-N), MW-1A (1.9 mg/L), MW-2 (2.2 mg/L), MW-2A (3.1 mg/L), and MW-3 (1.8 mg/L). Ammonia-N was detected at very low to trace levels in all other wells although reporting limits were above the MDL but below the PQL. These results are consistent with historic values.

TDS values in all wells were below the agricultural WQG of 450 mg/L and are graphed in Figure 10. The TDS:EC ratios for natural waters typically range from 0.55 to 0.75.2 The ratios in the second quarter 2022 ranged from 0.68 to 0.76 with an average ratio of 0.73.

Low (≤10 mV) oxidation-reduction potential (ORP) conditions were only present in MW-2 (-37 mV), MW-2A (-70 mV) and MW-3A (-57 mV). This is generally consistent with historical measurements, albeit slightly more oxidized. Fluctuations with time in ORP are shown in Figure 11.

DO values are within the historical ranges for that parameter. DO values in downgradient wells MW-2, MW-2A, MW-3, MW-3A, MW-4, MW-4A, and MW-5A ranged between 0.95 mg/L (MW-3A) and 2.46 mg/L (MW-2). DO values in upgradient wells MW-1 and MW-1A, 1 Hem, John D., Study and Interpretation of Chemical Characteristics of Natural Water, Geological Survey Water – Supply Paper H73, p63-64, 1978.

detected DO concentrations at 6.95 mg/L and 3.95 mg/L, respectively. Groundwater from wells is purged by the hand bailer method using dedicated disposable bailers.

The secondary MCL for manganese is 0.05 mg/L. Secondary MCLs are not health-based limits and this value is set at the concentration at which visible staining of plumbing fixtures can occur. Dissolved manganese exceeded the secondary limit in seven of the nine wells sampled this quarter; this is all groundwater the samples except MW-1 and MW-1A. The highest dissolved manganese concentration (6.4 mg/L) was in the crossgradient well MW-3A at the northwest side of the WWTF. This seems to further indicate that the manganese source is naturally occurring from lateritic bedrock conditions but are mobilized via oxidizing conditions along Sutter Creek. A 12-year upward manganese trend has been observed in MW-4 located down gradient from Pond 7 but it appears to have stabilized in recent years. A previous downward trend in MW-5A that started trending upward in December 2015 appears to also be normalizing. Total and dissolved manganese concentrations in groundwater versus time are plotted in Figure 8.

The secondary MCL for iron is 0.3 mg/L. Iron was not detected above MCL’s in any of the monitoring wells this quarter. Since liners have been installed into ponds, iron levels appear to have become almost undetectable across the entire facility. Total and dissolved iron concentrations in groundwater versus time are plotted in Figure 9.

The CDO specifies concentration limits for dissolved manganese and iron at MW-2, MW-2A, MW-3, and MW-3A. The October 2015, 2016, and 2017 Constituent Concentration Levels were not reached in time; anticipating this, the City submitted the 2020 Capacity Expansion Completion Report with information intended to meet the requirements on page 16 of the CDO Item 6B. In 2017, the City began draining and removing sludge from Ponds 1 through 4 in anticipating of lining these ponds. In the fourth quarter of 2019, the lining of the ponds was completed. The City is currently in the process of resolving the CDO. Long-term historic data as well as local hydrogeologic conditions indicate that the allegedly elevated manganese levels could be due to or related to naturally-existing conditions such as lateritic bedrock interacting with oxidized groundwater. Table B, Table C, and Table D are presented on the following page. These tables show the current concentrations in comparison with the 2015, 2016, and 2017 concentration limits.

8.0 CONCLUSIONS
-Various analytes that were tested as required for annual and quarterly monitoring were detected above MCLs.
-Coliform levels appear to show a pattern of slightly increasing in the wetter quarters (4th and 1st quarters) and lower in the dryer quarters (2nd and 3rd quarters). The contaminant appears to be naturally present in the groundwater both upgradient and downgradient although TCO levels are generally higher (and dissolved oxygen levels lower) under the wastewater facility. - Groundwater elevations for the WWTP wells in the second quarter of 2022 averaged approximately 1.04 feet lower than the previous quarter. - The secondary MCLs for dissolved manganese was exceeded in wells MW-2, MW-2A, MW-3, MW-3A, MW-4, MW-4A, and MW-5A. This is consistent with historic data.
- The secondary MCLs for dissolved iron were not exceeded in any wells. The trend has decreased and stabilized at trace to relatively low levels. - Secondary MCL for ammonia-N (1.5 mg/L) were exceeded in five wells (MW-1A, MW-2, MW-2A, MW-3, and MW-3A). Wells MW-1A, MW-2, and MW-3, appear to be on a decreasing trend, which may be due to the recently lined ponds and emerging oxidizing conditions.
- TDS concentrations were below the agricultural WQG in all wells. - The nitrate-N concentrations are below the primary MCL of 10 mg/L in all wells.

Historically, the highest nitrate-N concentrations are in upgradient well MW-1A but they now appear to be highest in downgradient well MW-4A. This trend will continue to be monitored.
. DO values in downgradient wells MW-2, MW-2A, MW-3, MW-3A, MW-4, MW4A, and MW-5A ranged between 0.95 mg/L (MW-3A) and 2.46 mg/L (MW-2).

These levels are within historical ranges.
- ORP values this quarter are similar to historical values. Lowest (≤10 mV) ORP conditions were present deeper monitoring wells (MW-2A and MW-3A). Well MW2 was the only other well where negative ORP levels were observed. All other wells show positive ORP results. This is consistent with historic ranges. - 10 -

9.0 RECOMMENDATIONS
EcoUrban Associates recommends the following:
- Change sampling frequency from a quarterly basis to a semi-annual basis due to consistent trends that been established and revise the existing MRP No. R5- 2013-0022 (Rev1) accordingly.
- CDO No. R5-2014-0157 should be lifted due to evidence indicating that manganese and iron levels are naturally-occurring.

Agenda Item #8(a-c)
DATE: August 2, 2022
TO: MAYOR EPPERSON AND CITY COUNCIL
FROM: MICHAEL ROCK, INTERIM CITY MANAGER
SUBJECT: RESOLUTIONS # 2022-13, 2022.14, AND 2022-15 OF THE CITY

COUNCIL OF THE CITY OF IONE, ACTING IN ITS CAPACITY AS

THE LEGISLATIVE BODY OF THE COMMUNITY FACILITIES
DISTRICT NOS. 2005-2, 2006-1 and 2009-3 OF THE CITY OF

IONE AUTHORIZING THE LEVY OF SPECIAL TAXES FOR
FISCAL YEAR 2022-2023
RECOMMENDED ACTION:

That the City Council:
• Approve Resolution No. 2022-13 of the City Council of the City of Ione, acting in its capacity as the legislative body of the Community Facilities District No. 2005-2 of the City of Ione (Edgebrook and Castle Oaks Phase II) authorizing the levy of special taxes for fiscal year 2022-2023. • Approve Resolution No. 2022-14 of the City Council of the City of Ione, acting in its capacity as the legislative body of the Community Facilities District No. 2006-1 of the City of Ione (Wildflower-Public Safety Services) authorizing the levy of special taxes for fiscal year 2022-2023. • Approve Resolution No. 2022-15 of the City Council of the City of Ione, acting in its capacity as the legislative body of the Community Facilities District No. 2009-3 of the City of Ione (Castle Oaks Phase II) authorizing the levy of special taxes for fiscal year 2022-2023.

SOURCE OF FUNDING:

All CFDs are special tax levies pursuant to Section 53340 of the Government Code and Ordinance Nos. 392, 427 and 428 respectively.

DISCUSSION:

There are various annual reporting requirements with different reporting dates related to the City of Ione Community Facilities District Nos. 2005-1, 2005-2, 2006- 1 and 2009-3 (CFD Nos. 2005-1, 2005-2, 2006-1 and 2009-3). The requirements include, among other items, City Council approval of the “Annual Levy of Special Tax” resolutions authorizing the levy of special taxes within CFD Nos. 2005-1, 2005-2, 2006-1 and 2009-3. The annual levy is necessary to pay debt service on the outstanding bonds and to pay for certain public services. Approval is due each 2 year prior to the County of Amador’s August 10th deadline for the inclusion of such special taxes on the consolidated property tax bills pursuant to Government Code Section 43340 of the Mello-Roos Community Facilities Act of 1982 (the Act), or in the case of direct billing, at a different time or in a different manner if necessary to meet its financial obligations.

CFD No. 2005-1 was established on February 22, 2005, and the special taxes were for facilities. CFD No. 2005-1 encompassed 211 residential homes and the golf course clubhouse. The CFD No. 2005-1 Special Tax Bonds had a final maturity of September 1, 2016. Accordingly, parcels within CFD No. 2005-1 are no longer subject to the levy of special taxes. Furthermore, a notice of cessation of the special tax for CFD No. 2005-1 has been recorded with Amador County evidencing that the special tax lien imposed on the parcels within CFD No. 2005-1 has been extinguished.

CFD No. 2005-2 was established on June 6, 2006, and there are three improvement areas. They are: Improvement Area No. 1, Improvement Area No. 2 and Improvement Area No. 3. Each Improvement Area has a facilities special tax (Special Tax A) and a services special tax (Special Tax B).

Improvement Area No. 1 encompasses approximately 34.8 acres and contains 140 residential units. Subsequent to the issuance of Improvement Area No. 1 Special Tax Bonds, 39 homeowners have elected to fully prepay their applicable facilities special tax obligation, and 101 remaining residential parcels will be subject to the levy of the facilities special tax. For fiscal year 2022-2023, 140 residential parcels will also be subject to the levy of the services special tax since building permits for all such parcels were issued prior to May 1, 2022.

Agenda Item #9
DATE: August 2, 2022
TO: Mayor Epperson and City Council
FROM: Michael Rock, Interim City Manager
Julie Millard, Management Analyst
SUBJECT: Approval of Resolution No. 2022-17 Authorizing Placement of Delinquent Sewer Accounts and Administration Fee to be Submitted to Amador County to be including on the Current Year Tax Roll.

RECOMMENDED ACTION:

1. Adopt Resolution No. 2022-17 authorizing the levy of delinquent balances, as of May 31, 2022 (June billing), along with a $50.00 per parcel administration fee, to be included on the Amador County 2021-22 tax roll.

FISCAL IMPACT:

Historically, once per year the City of Ione places seriously delinquent sewer accounts with Amador County to be collected as a lien on the property owner’s annual tax assessment. This form of collection is addressed in the City of Ione Municipal Code, Chapter 13.42.060. In 2017, City Council approved Ordinance 495 which established a $50.00 per parcel administration.

BACKGROUND:

In order to have the levy placed on the upcoming tax roll, Amador County AuditorController’s Office requires a current resolution, list of parcel numbers and the amount of levy to be submitted to their office by the second week in August each year.

At this time the attached list of sewer accounts have been identified as being more than 90 days delinquent. On June 13, 2022, customers were notified by letter that full payment must be received no later than July 15, 2022 to avoid having their past due balance placed on the County tax roll. Notification of this delinquency was mailed to the owner of records, in addition to the monthly billing statement, which details current and prior balances due.

13.52.060 - Enforcement.

In the event of the failure of any person billed or the owner of the premises to pay when due any sewer service charges applicable to premises owned by him, the city may enforce payments of such delinquent charges in any of the following manners:

The city may have such premises disconnected from the sanitary sewer system. In the event such disconnection should create a public hazard or nuisance, the superintendent or his representatives may enter upon the premises for the purpose of doing such things as may be reasonably necessary to alleviate or remove such hazard or menace. The owner of such premises shall have a duty to reimburse the city for all expenses incurred by city in disconnecting any such premises, or in doing other things authorized by this section; and no reconnection shall be made until all such charges are paid.

The city clerk may institute action in any court of competent jurisdiction to collect any charges which may be due and payable in the same manner as any other debts owing to the city may be collected.

As an alternative procedure, the city may provide any and all delinquent payments be placed on the tax roll, and collected with property taxes, as provided in Chapter 13.56.

The city may provide otherwise for the collection of such delinquent charges. All remedies provided for in this section for their enforcement and collection are cumulative and may be pursued alternatively or collectively as the city determines. If any remedy is invalid, all valid remedies shall remain effectual.

The city shall collect, in addition to any sewer service charge or penalty or interest assessment, an administrative fee calculated on the actual costs of the city for collection actions described in this section or as described in Chapter 13.56 of this Code. ( Ord. No. 495 , 9-5-2017; Ord. 323 § 2(part), 1992).

Over the years, Council has approved revisions to the chapter to provide additional details relating to the terms, commission meetings, etc.

In early 2022, a local high school student expressed interest in being a Parks and Recreation Commission Youth Advisory member. It was at that time, staff determined that the ordinance did not specifically allow for Youth Advisory members. However, City Code of Ordinance Chapter 2.36 – Parks and Recreation Commission, Section

2.36.020 – Membership, Item E, provides that the City Council may appoint advisory personnel to assist the commission with its purpose. On March, 15, 2022 (Item #7), City Council appointed its first advisory member using this section.

Staff now desires to amend the ordinance to allow for youth advisory members, outline youth advisory member’s requirements, term, and purpose, and to make minor formatting edits.
