What is Stormw ater?

Stormwater is site runoff or runon from:

• Rain
• Snow, sleet, hail
• Snowmelt

When contaminated with site materials, stormwater affects water quality

3

Why Do We Care about Stormw ater?

• Mismanaged fluids and sediments that

contaminate stormwater, lead to polluted lakes and rivers

• Affect:
• the ability of aquatic life to survive
• fish spawning areas and
• food source habitat

4

Why do YOU YOU care about stormw ater?

• Benefits of complying with our

Industrial Stormwater Permit:

• Increased efficiency through pollution

Prevention (saves you $)

• Increased compliance in solid

waste/hazardous waste

• Protection of Minnesota’s waters
• Ramsey County is Happy!

5

Who Must Apply for a Stormw ater Permit?

Facilities with activities that fall into one of ten categories of industrial activity, including:

• Sector M: Automobile Salvage Yards: SIC 5015
• Sector N: Scrap and Waste Material Recycling:

SIC 5093

Complete list of SIC codes are in application instructions

6

What’s Included in Sector M & Sector N ?

Dismantling or wrecking motor vehicles for the purpose of recycling or selling parts or scrap, wholesale or retail:

• Automobile engines
• Automobile parts
• Motor vehicle parts
• Motor vehicle scrap
• also-
• Assembling, breaking up, sorting, and wholesale

distribution of scrap and waste materials (Sector N)

7

What Industrial Activities Are Significant?

8

What Industrial Materials and Activities Are Not Significant?

• Containers and tanks sealed

and free from deterioration

• Adequately maintained yard vehicles
• Completely covered/plugged dumpsters
• Materials that are stored outside that do

not cause polluted runoff

• Office buildings and office parking lots

9

Sources of Pollutants:

• Fluids from vehicles
• Refrigerants
• Mercury switches
• Leaking batteries
• Lead parts
• Solvents and contaminated rags

10

Pollutants We Are Concerned About for Sector M/N

• Total Suspended Solids (TSS)
• Total Aluminum (health effects, aquatic life)
• Total Iron (staining, clogging; at high levels;

aquatic life)

• Total Lead (a nerve toxin)
• Total Mercury (a nerve toxin)
• Oil and grease, fluids (may contain metals)

11

Remove fluids to avoid soil contamination and contaminated stormwater

12

Staining indicates soil contamination that can move with stormwater flow

13

Storing batteries indoors or under cover avoids leaking battery acid which contaminates soil & water

14

Good Housekeeping Avoids Contamination of Stormwater

Stream Impacted by Sediment

17

Industrial Stormw ater Multi-Sector General Permit

Requirements:

• Development of a Stormwater Pollution

Prevention Plan (SWPPP)

• Create Best Management Practices

(BMP’s)

• Benchmark monitoring—

this is new

18

Sector-Specific Requirements

Each sector would have specific requirements for:

• What pollutants to monitor for and how
• ften
• Sector-specific benchmarks
• Some specific BMP’s
• Multi-sector requirements

19

Areas to Assess for Pollutants

• Vehicle fluid, fuel transfer & storage areas
• Vehicle dismantling areas
• Vehicle storage areas
• Parts storage areas
• Parts maintenance areas
• Tire storage areas

20

BMP’s Required for Sector M and N

• Drain vehicles of fluids
• Inspect vehicles and equipment for signs
• f leakage
• Inspect areas where vehicles, parts,

batteries and fluids are stored

• Inspect storage areas for mercury

switches

• Train employees in handling of vehicle

fluids, fuels, solvents, mercury switches, refrigerants

21

BMPs to help minimize Stormw ater Contamination:

• Work inside buildings
• Indoor battery storage
• Manage runoff/runon
• Good housekeeping
• Recycle fluids, fuel, batteries, mercury

switches, lead battery cable ends and wheel weights

• Salvage Yard Manual

22

23

You Have Choices in BMP’s to Use

• Plan your BMP’s early
• Document BMP’s in your

SWPPP

• Use your SWPPP as a guide

to manage your site

24

Benchmark Monitoring Sector M & N

• Inspect, manage, maintain BMP’s.
• Sample 4 times in the 2nd

year of the permit, compare average to benchmark.

• If you fail benchmark, make changes to

BMPs, document in the SWPPP, repeat benchmark monitoring.

• If benchmark is exceeded again, a report

must be submitted. May need an individual permit.

25

How Do I Obtain the Permit?

• Apply now, if you currently do not have

coverage

• Apply for new permit
• No permit fee-annual fee only. Fill out

annual reports, self-inspect.

• If your facility already has an individual

discharge permit, stormwater requirements will be inserted.

26

What is No Exposure?

All significant industrial materials and activities are protected from:

• Rain
• Snow
• Snowmelt
• Run-off

by a storm resistant shelter

27

What Advantage is Achieving No Exposure?

• Conditional exclusion from the industrial

stormwater permit

• No SWPPP, no annual fee, no annual

reports, no monitoring

• Ramsey County will appreciate your

efforts!

• Stormwater contamination is

avoided=happy fish!

28

How Do I Obtain No Exposure Exclusion?

• All significant materials/industrial activity

protected from stormwater

• Submit the permit application and No

Exposure Certification Section every 5 years

• Submit a copy of the certification, upon

request, to the municipality in which the facility is located
