SMARTS Navigation
•Only a Legally Responsible Person (LRP) or Duly Authorized Representative (DAR) can certify reports.
•Who should be the LRP?• SDCOE FACJPA recommends Assistant Superintendent or above
• More than one LRP can be designated
•Who should be a DAR?• SDCOE FACJPA recommends Director of Transportation or similar
• Not required, but a DAR can certify reports for the LRP
•At least 2 individuals should have certification rights (either 2 LRPs or 1 LRP and 1 DAR)
SITE EVALUATIONS
10/12/2017
6
• When: Every Month• Once a month, every month of the year.
• Within daytime operating hours
• On days without precipitation
•What to observe:• “Outdoor industrial equipment and storage areas, outdoor industrial activities areas, BMPs, and all other potential source of industrial pollutants.”
• Your forms are specific to your facility• All drainage areas listed are applicable; ensure no industrial activities are occurring in non‐industrial areas (i.e. parking only) or tracking out of contained areas
• Use your site map for reference
Visual Observations: Monthly
Visual Observations: Monthly
• Walk and observe entire facility (includes adjacent, non‐industrial areas)
• Set a recurring event early in the month
• Ensure nothing is flowing to drains
• If a discharge is found, describe how it was stopped.
• Ensure all outdoor areas are clean.
• It is OK to note a deficiency, but a resolution must also be noted.
• What next?
• Check for completeness
• Send copy to Sally and Annika ASAP

MONITORING
Sampling Events
When do I collect a sample?• First sample: July‐December
• Second sample: January‐June
• During a qualified storm event (QSE):
• No runoff for 48 hours prior to the event
• Generates runoff during operating hours
•Within 4 hours of:
• The start of runoff, OR:
• The start of facility operations (if runoff started within the prior 12 hours)
• Within daytime operating hours under safe conditions

Sampling Events
Where do I collect a sample?
At all INDUSTRIAL discharge points that have storm water runoff
• Refer to your site map
• Refer to your sample form
AFTER treatment
Where water is flowing, not puddled
Sampling Events
•How do I know what time run‐off started, if I wasn’t there?• Runoff from a paved site is expected at around 0.1 inches
• Check your nearest weather station: www.wunderground.com/history
• OR‐ install a weather station on site
•How do I know if it is supposed to rain?• http://forecast.weather.gov/MapClick.php?lat=32.8982&lon=‐117.2028#.V‐B7NvkrKUk
•What if I won’t be around?• Check in with your alternate sampling staff• If all are unavailable, call Annika (858) 586‐6600 x20; D‐Max staff can take your sample for you (fees apply)

Sampling Events: Supplementary Testing
• If you are in Level 1 or 2, or are in baseline but your first sample had exceedances:• It is recommended to sample more than the minimum QSEs, in order to bring down your average.
• Supplementary testing only needs to include the pollutants that are over the NAL. (Less money!!)• Only conduct supplementary testing if you have reason to believe the results will be below NALs.
•You still need to test your full kit the standard 2x/year
•Annika will advise you of these options in your sample analysis letter
Visual Observations: Sampling Event
•When: During Sample Collection• Complete at the time of sampling.• Complete at every sample point.
• ONLY look at the final flow, nothing prior to passing through fiber rolls, booms, or sandbags.
•What am I looking for?• Pollutants actively flowing offsite (at discharge points)• Floating/suspended materials• Oil and grease• Discolorations• Turbidity• Odors• Trash/debris
10/12/2017
10
Visual Observations: Sampling Event
•What if I do see some pollutants?• Place sandbags, fiber rolls, oil absorbent booms, etc. to eliminate pollutants.
• If ANY pollutants marked “Yes,” or pH is less than 6 or more than 9; find out why, take action, and record what was done about it on the form (i.e. swept, replaced boom, placed work order, etc.).
• Send copy of form to Sally and Annika ASAP (needed before your analysis letter and SMARTS report can be completed)
Visual Observations: Sampling Event
•Measure the pH and record on your form• Dip paper strip into flowing water for a few seconds or until paper is wet
• Immediately compare color of paper to the guide on the package (to the nearest 0.5)
Acceptable Range
If pH is less than 6 or more than 9, take it again to be sure

Storm Water Sample Collection•Where possible, use a clean sample bottle to collect water directly or fill other bottles
• If another container is used, ensure the container is clean, and rinse with sample water before collecting
• Remember:• Avoid leaves & dirt
• Sample FLOWINGwater
• Sample AFTER treatment (straw wattles, sandbag berms, vegetated swales, etc.)
•GENTLY place sample container into flow, never scrape against the ground.
Storm Water Sample Collection
•Wear gloves
• Fill bottles with preservatives first (Blue/Green dots)• Fill to the neck of the bottle, do not overfill
• Small vials: fill to brim, • Turn bottle upside down to check for bubbles
• If pea‐sized or smaller bubble exists, you are done
• If larger bubble exists, add more water and check again
• Label bottles with discharge point #, date, and time, repeat on Chain of Custody form
• Place bottles in cooler with ice

Sample Delivery
• Call EMA to notify of drop‐off time4340 ViewridgeAve. Ste. ASan Diego, CA 92123
(858) 560‐7717
• Don’t leave the lab without your replacement kit
• How fast does the sample have to get to the lab?•Within 48 hours
• Remember, the lab is not open on Sundays, and Saturdays only if you arrange it ahead of time
• Samples must remain on ice
• If shipping , complete “Relinquished by” section of Chain of Custody. If delivering, wait until arrival at EMA.
How do I fill out the chain of custody?

Numeric Action Levels (NALs)
•What happens if I have an NAL Exceedance?• Enter Level 1 for that pollutant:
• Complete evaluation by Qualified Industrial Storm Water Practitioner (QISP)
• Identify BMPs and SWPPP revisions
• Submit Level 1 ERA Report
• $$
• Takes 4 QSEs without NALs to return to baseline
• Continued NAL exceedances will result in Level 2:
• Involves preparing an action plan, technical report, BMP demonstration, etc.
Numeric Action Levels (NALs)
•What happens if I enter Level 2?• Level 2 Action Plan in first year
• Level 2 ERA Technical Report and BMP Demonstration in second year
• Thousands in additional costs per year, PLUS the cost to implement additional BMPs (BMP‐dependent)
• Takes 4 consecutive Qualified Storm Events (QSE) to move down to baseline
• Goal: Stay at baseline! • Plan B: Stay at Level 1!

Pollutants of Concern
• Primary Concerns for District Maintenance Facilities:• Zinc
• Copper
• Dirt (Total Suspended Solids)
• Oil & Grease
• Primary sources:• Tire wear dust, Galvanized metal
• Brake dust
• Erosion, vehicle tracking
• Leaks and improper oil storage
COMPLIANCE STRATEGIES
10/12/2017
16
No Exposure Certification
•All maintenance, fueling, and washing activities contained indoors
• OR
• Within cover and containment (bermed and/or draining to sewer)
• If this applies, there are no more industrial activities, only an annual certification
LET’S TAKE
THIS
INSIDE!
No Exposure CertificationTips
•Wash within contained bay
• Fuel and/or wash offsite
• Use berms to contain areas
• Plumb contained areas to sewer
• Ensure design will capture all potential spills and tracking• Angle bus wash aprons back into containment to collect overspray and drips
• Allow a buffer between activities and outdoor areas

Infiltration
Eliminate runoff = no sampling!
• Keep what’s yours!
• If it doesn’t leave your property, you don’t need to sample it
• Redirect flows to landscaping for infiltration
• Pervious pavement, bioswales, and other installations also promote infiltration
Treatment
• Remember that treatment doesn’t replace BMPs!
• Treatment devices require maintenance
• New treatment must meet design standards:• http://www.sandiegocounty.gov/dpw/watersheds/susmp/susmp.html
• Treatment devices have different pollutant removal efficiencies

Treat Runoff
The most effective removal of sediment and heavy metals is to filter water through soil/sand.
• Bioretention
• Infiltration
Slow Runoff
Tips
• Use sandbags to slow the water down
10/12/2017

Slow runoff
Tips
• Check‐dams and fiber rolls can be used in series to slow the flow upstream and reduce pollutants
POLLUTANT SOURCE CONTROL
10/12/2017
20
Source Control
Zinc
• Anything galvanized• Roofing, siding, fencing
• Tires
• Cover, coat, or remove
Copper
• Brake and tire dust
Source Control
Zinc and Copper
• Mechanical sweeping is ok for trash and leaves, but not dust
• Vacuum‐assisted sweepers can pull the dust out of the asphalt
• Supplement with shop‐vac by hand where the sweeper doesn’t reach
• Also found in used fluids (oil, antifreeze)
• Steam cleaning only effective if waste water is vacuumed up
10/12/2017
21
Source Control
Zinc, Copper, and Total Suspended Solids
• Maintenance issues like cracks or crumbling asphalt allow dust to collect, and add additional sediment to storm water.
• Fill cracks, repair, or reseal pavement as possible.
• Maintain unpaved parking areas• ‐Add gravel to prevent soil exposure and track‐out
• Contain slopes and landscaping• ‐Vegetate, or stabilize with mulch, fiber rolls, or hardscape
