Yes —they will not likely be added within the next 5 years (Jim, Trevor— please confirm). However, those ponds are only
designed to receive flow from a vegetated berm.

Those east and west berm ponds are part of very -far -in -the -future modifications, correct? I would advise adding those
later if necessary. Will the stormwater from them be associated with the mining activity at all?

Bethany — this looks correct, and yes, there is no Outfall 007.
I apologize, but there are two additional outfalls that need to be included: there are two berm ponds that will be
located north of the quarry. These ponds will collect stormwater only from the perimeter berm and will discharge to an
unnamed tributary to Robeson Creek. However, these will not discharge and stormwater in contact with process areas.
Do they need to be included with the permit?
Sorry for the confusion. This is a very large site.
Thanks,
Chris

Thank you, Chris.
Below are the outfalls I have entered into the system for your reference. These are associated with the modification
request we are processing to add Stinking Creek as a potential receiving water of stormwater discharges to the
COC. Can you review to make sure I've got them all correct?
Outfalls 002-006 discharge to Rocky Branch. Outfall 003 is WW; the others are SW.
Outfalls 001 and 008 are not listed here because they have ROS . It would be helpful to include those in the list and note
ROS. Can you provide location info?
There is no Outfall 007 (please verify)
Future Outfalls 009-014 discharge to Stinking Creek

Bethany — I apologize for the delay. To clarify, Ponds 001 and 01A do not discharge through Outfall 003 (003 is the
dewatering outfall located by the quarry). Outfall 001 discharges from Ponds 001 and 01A. Meanwhile, Outfall 008
discharges from Pond 003. Both Outfalls 001 and 008 discharge to Rocky Branch and receive stormwater from the
stockpile area; however, neither is sampled, as 3M uses representative Outfall 005 to characterize discharges from this
area. 3M previously worked with DEMLR to determine which outfalls could be considered representative.
I hope this clarifies things a bit. Please let me know if you have additional questions.

Thanks, Chris. I do not have any information for the Outfall 008 that Jim refers to. Do you have coordinate and
description info for that one?
Also, the way I follow this, there is no Outfall 001—just a Pond 001 that goes to outfall 003. Is that correct?

Bethany - the pond 1 outfall will still discharge to Stinking Creek. The outfall remains the same.
For pond numbering, I will defer to Jim with 3M.

Hi, Chris,
I'm finally getting around to entering this outfall information into BIMS. I have a couple questions:
New Ponds 4-9 will discharge to Stinking Creek. You have coordinates for a New Pond 1 (and I see Ponds 1 and 1A on
the plans submitted). Where does this discharge? And is this considered a new Outfall 001?
Also, how do you want me to enter outfall numbers for Stinking Creek (Ponds 4-9)? 1 could do something like "P004"
"P005" etc., or 014, 015, etc.
Thanks,
Bethany

Bethany—Outfall 003 discharges precipitation collected from the quarry (dewatering), while the other outfalls all
discharge stormwater. Descriptions for the existing outfalls include:
• Outfall 002 - Spillway from stormwater pond 2 which controls stormwater runoff from the 3M
manufacturing area.
• Outfall 003 - Mine dewatering collected at discharge from quarry dewatering ponds 1 and 2.

Outfall 004 — Stormwater discharge pipe to Rocky Branch conveys stormwater runoff from haul road.
Outfall 005 - Spillway from stormwater sedimentation ponds 2 and 2A which control stormwater runoff
from the overburden/mineral fines storage pile.
Outfall 006 — Spillway from the stormwater pond that controls water runoff from the aggregate processing
area and from Luck Stone's vehicle maintenance area.
All of these are currently sampled.
Please let me know if you need additional information.
Thanks,
Chris

Bethany - I spoke with 3M, and they believe there is a chance that they could construct one of the ponds that discharge
to Stinking Creek prior to the expiration of NCG02 in 2020. That said, we would like to move forward with amending the
CoC. I responded to your questions below in red.
1. Will any of these discharges be considered wastewater under the NCG02 general permit? We do havesome
guidance on that on our website if there's a question about it. The letter indicates stormwater, but I want to
verify -especially since these new waters are water supply, and we would need to check with DWR Public Water
Supply if any proposed discharges are wastewater.The discharges will not be wastewater as they will only be
comprised of runoff generated from a perimeter berm or stockpiles of overburden and rock.
2. Is it possible to provide latitude/longitude coordinates for all of the outfalls (current and proposed) for this mine
site? Eventually we need to add these to BIMS so the permittee can use eDMR to electronically report
monitoring data. This is a good opportunity for us to take care of NCG020330. See the below tables.
3. What type of material is mined here? Andesite -the rock is used for roofing granules.

Please let me know if you need additional information. The SWPPP has already been amended to account for the new

after which, they would be require to sample that new location.

Subject: 3M Submittal for Stormwater NCG020330
Hi, Chris,
Thanks again for submitting the updated information for 3M's quarry expansion. I have a few follow-up questions... The
letter says the new ponds will discharge stormwater to UTs to Stinking Creek and UTs to Robeson Creek (all WS -IV;
NSW), which are not currently on the COC. Because only Rocky Branch, class C, is on the permit, we may need to issue a
modified COC.
1. Will any of these discharges be considered wastewater under the NCG02 general permit? We do havesome
guidance on that on our website if there's a question about it. The letter indicates stormwater, but I want to
verify—especially since these new waters are water supply, and we would need to check with DWR Public Water
