Transcript of CWQMC/CMF Navigating Reg 85

What needs to be tested?
Nitrogen and Phosphorus
1. Upstream of the discharge

2. Downstream of the mixing zone at the closest active USGS gaging station or DWR Stations
At Gaging Stations
Reg 85 seeks to gain statewide information about nutrients – not necessarily tie information to a single discharger.
Active flow gage stations have the benefit of being able to rely upon publicly available daily flow records and thereby relieve the entity of the necessity of measuring flow as well as taking the water sample.
Gaging Stations
Colorado Division of Water Resources Website
http://www.dwr.state.co.us/SurfaceWater/default.aspx
Click on your basin and search by stream name
Has both USGS and DWR sites

USGS Water Watch
http://waterwatch.usgs.gov/index.php?m=pa01d&r=co&w=map
Will give map view or Google Earth file of all USGS gages for selection
Does not contain information on DWR gages
If established gaging station is not available or is located significantly downstream, an alternative stream flow calculation may be used

No method is currently established but you could possibly:
Calculate flow:
upstream gage + gaged tributaries – gaged ditches
or
Evaluate flow using a transect of flow meter measurements
Alternative to Downstream Gages
Alternative Plan should be sent to:

The Road to Regulation 85
A decade of navigating to where we are now:
September 2002 - CDPHE sent EPA a Nutrient Criteria Development Plan
2002 - 2010 - Nutrient Criteria Groups meet
October 2010 - Stakeholders proposed a technology based regulation that would evolve into:
Regulation 85 Nutrients Management Control
January 2011 - Water Quality Control Commission delayed Rulemaking Hearing on Reg. 31 and 85 for a Cost-Benefit Analysis to be conducted
March 2012 - WQCC Rulemaking Hearing approved the final proposal of Regulations 31 and 85.


Monitoring for Reg 85 is to begin by March 2013
Regulation 31 contains interim numeric nutrient water quality values. These interim nutrient values likely will form the basis of future enforceable water quality standards.

The purpose was to provide a stepwise process for dischargers to assess their facility needs to meet future Regulation 31 values.

Prior to the adoption of Reg 31 based water quality standards monitoring will take place under Reg 85 to provide a more complete water quality picture throughout the state.
Regulation 31 and Regulation 85
Effluent
Downstream
Upstream
How to Get There
Dischargers must begin monitoring by March 1, 2013
The following references are available on the WQCD website:
Regulation 85 SAP Certification Form
Regulation 85 Monitoring Panel
Regulation 85 Monitoring Flow Chart
Monitoring Question and Answers for Regulation 85
The Colorado Water Quality Monitoring Council (CWQMC) and Colorado Monitoring Framework (CMF) have been developing documents to assist in implementing Regulation 85.
SAP
Regulation 85 requires a Sampling and Analysis Plan (SAP)
(Not required to submit plan but must certify that you have one).
The Colorado Water Quality Monitoring Council (CWQMC), Colorado Monitoring Framework (CMF) and CDPHE have developed a Sampling and Analysis Plan that can be used by a discharger or watershed group.
This basic Sampling and Analysis Plan has blanks to be filled in for each unique discharger or watershed group. Anyone required to monitor for regulation 85 can use the Sampling and Analysis Plan.

If all dischargers are using the same basic plan, the data collection efforts will be more consistent.
Regulation 85 SAP Certification
This short form, must be
submitted to CDPHE
by March 1, 2013
The Sampling and Analysis Plan contains forms and instructions to assist you in your monitoring:
Regulation 85 SAP Certification form
A Chain of Custody form that can be used when taking samples to your laboratory
Tables with information on sampling methods
Coming soon - A basic excel template to store your data after you receive your results from your laboratory
In the first section the blanks are filled with your facility name, address and permit number.
The main body of the Sampling and Analysis Plan contains the monitoring location information, who conducts the sampling and the laboratory that will analyze the samples.
UPSTREAM
SITE
No requirements like downstream sites

BUT there are considerations...
Selection of Sampling Sites
Sampling sites are typically chosen based on:

Accessibility
Representative of parameters
Proximity to volunteers
Value to potential users
Location in a problem area
Safety

Always remember your monitoring goals when selecting sites.
Access
When establishing new sampling locations, make sure that it can be sampled easily by gaining necessary permissions.

If on private land, you should approach the landowner for permission to access their property.

Grab samples can be obtained from a bridge using a sampling device. Typically no access permissions are needed because roads are public.
Public land can also be a great resource:
the river can be accessed from parks, state wildlife areas, USFS or BLM land or other publicly accessible areas. If you are sampling on public land, you may get additional information by contacting employees from the appropriate agency. They might be sampling already.
At any site you must also consider how to physically access the site.
- Will you be dropping a sampling device or using waders to enter the stream to sample?
- If you are planning on entering the stream, think about conditions during both low and high flow events.
Is the site representative of the watershed?

Is the site far enough downstream of drains or tributaries (i.e. below mixing zone)?
Is the site representative of the parameters you are looking for?
Have you selected enough sites to accomplish your goal?

Can you identify this site on a map and on the ground?


Use CDSN to see if there are established sites in your area

http://coloradowaterdata.org/webmap.html

By sampling at an established station you may be able to leverage existing data.
What Are We Sampling and Reporting?
Phosphorus
Nitrogen
Flow
Effluent Monitoring
Phosphorus: Total Phosphorus

Nitrogen: Total Nitrogen

Flow: Daily average flow (typically from a downstream gaging station).
NITROGEN
Many different forms of Nitrogen
Different ways to get to Total Nitrogen
Total Nitrogen (TN) =

(TIN + TON)
or
(NO3 + NO2 + TKN)
TIN = Total Inorganic
Nitrogen =

NH3 + NO3 + NO2
TON =
Total Organic Nitrogen
=
TKN - NH3
NH3 = Ammonia
NO3 = Nitrate
NO2 = Nitrite
These three components add up to TIN which is
Total Inorganic Nitrogen
TKN =
Total
Kjeldahl
Nitrogen
Analyze samples for:
Ammonia (NH3)
Nitrate (NO3)
Nitrite (NO2)
TKN

You will have the necessary components to get Total Nitrogen (TN) and Total Inorganic nitrogen (TIN)
Bottom Line
Detection Limits by Sample Type
Upstream & Downstream (MDL) -
Total Phosphorous 0.01 mg/L
Nitrate + Nitrite (N)0.02 mg/L
TKN 0.1 mg/L
TN 0.1 mg/L

Effluent (PQL)-
Total Phosphorous 0.01 mg/L
Nitrate + Nitrite (N)0.5 mg/L
TKN 0.5 mg/L
TN 0.5 mg/L
NH3 0.05 mg/L

BEFORE SAMPLIng
Get organized …. Make a plan

Prepare and label bottles

Clean and organize equipment such as your sampling device, meters and waders.

Include a camera -pictures can help identify conditions or differences in flow.

Include a cell phone

Check vehicle, gas

Check weather and gages - the gage can give you an idea of river flow.

Note possible safety concerns
AFTER SAMPLES ARE COLLECTED
Identify container, Use permanent ink

If it doesn’t feel safe …. Sample some other time
SAFETY
SAMPLING EVENTS
Consider coordinating with other groups
- Data will be more comparable
- Save time and effort by working with a Watershed Group

Sample as Early in the month as possible
- Gives you time to redo in cases of bad weather or broken samples
(Murphy Proofing)
- Labs will love you! (Check with lab for good days - some analyses are short holds!)
- Facilitates timely data reporting (the state will love you!)

Consider Sampling the same week and day of the week each month- This ensures a consistent schedule

Phosphorus: Total Phosphorus

Nitrogen:
Total Nitrogen and Total Inorganic Nitrogen

Flow: Total daily flow (in gallons or MGD) on the day that nitrogen and phosphorus samples are collected. Typically same value as in permit.
Monitoring
Small Dischargers < 1 MGD
Sample Effluent ONLY
Sample 6 times per year
Must Certify that you have a SAP
Large dischargers > 1 MGD
Sample Effluent and Streams (up and down)
Sample 12 times per year
Must Certify that you have a SAP
ALL Dischargers
Stream Monitoring
(For dischargers > 1 MGD)
The CWQMC is dedicated to facilitating water quality monitoring and seamless data sharing among all interested parties to accurately characterize water quality in Colorado. Our vision is to have scientifically sound and accessible data and facilitate an open and informed discussion about water quality in Colorado.
Colorado Water Quality Monitoring Council
The Colorado Monitoring Framework (CMF) is a consortium of stakeholders interested in creating a collaborative process to comply with nutrient water quality regulations in priority basins, e.g., the South Platte and Arkansas. The CMF is also interested in collaborative sampling and analysis activities to address other water quality issues such as temperature.
Colorado Monitoring Framework
UTRIENT
SAMPLING
When wading, collect samples upstream from the body to avoid disturbing sediments.
Sampling near structures like dams, weirs, or bridges may not provide representative data because of unnatural flow patterns.

If you sample from a bridge, take samples from the upstream side.
Collect grab samples within the top 12 inches of the water column, but avoid skimming the surface of water during collection.
Preserve Samples according to laboratory instructions.
Sampling and Analysis Plan (SAP)
Webinars
Data Submission Template (Coming Soon!)
If you choose not to sample at a gaging station downstream, you must report daily average flow using an alternative method – more on this later.
FLOW
Coordinated sampling sites

If multiple dischargers are above a single gage, each entity would have the option of sampling it together to save resources. Extra funds and effort could be used to:

Save time and money for everyone

Allow additional funds to sample for more compounds or sample more often
Watershed Groups
WATERSHED GROUPS
Gather more data at more locations to form a better water quality picture
Reduce monitoring costs – both in sampling and lab processing
Reduce duplication of efforts that produces data that is not useful
Create a group of individuals who can come together to expertly discuss and solve water quality problems
Advantages of Collaborative Monitoring Through a Watershed Group
Same day sampling can lead to robust datasets that can easily be used to model water quality constituents.
This provides a better understanding of water quality in a watershed.
With your organization:
check out the sample SAP
consider site placement
consider coordination with others

Continue to watch the Q & A on the Division website - it will be updated regularly.

Tune in to our 2nd webinar on
February 20th from 2-4 pm which will cover:
Lab Methods and Options
Data Storage and
Submission
