Industrial Materials
Because not all co-permittees conduct all of the industrial activities described in Section 4,
COPAD has organized CMs by industrial activity. Co-permittees can use the CMs that
apply to their activities. Attachment 3 contains CMs for each of the ten industrial activities
listed in Section 4, and a general CM that applies facility-wide. Each activity-specific CM
lists the targeted sub-activities, target pollutants, specific procedures addressing the CM
categories listed above, record keeping/reporting requirements, and stormwater pollution
prevention considerations for the design of new facilities or upgrades to existing facilities.
These CMs are in general used by COPAD and co-permittees and are based on the
requirements of the MSGP-2010 and COPAD-specific operational requirements.
Some CM categories do not apply to PHX or are covered under good housekeeping
requirements. These are described below:
Salt Storage: Salt storage is not conducted at PHX so no specific CMs have been developed
for this category.
Sediment and Erosion Control / Dust Generation and Vehicle Tracking: MSGP-2010
requires that the SWPPP identify areas with a potential for significant soil erosion due to
topography, land disturbance (e.g., construction) or other factors, and the structural,
vegetative, and/or stabilization CMs that will be implemented to limit erosion. These are
the same areas likely subject to dust generation and vehicle tracking.
For the most part, soil erosion potential at PHX is limited to land disturbance due to
construction. PHX facilities are frequently subject to expansion and modification
construction projects. Due to the relatively continuous and changing nature of
construction projects at PHX, it is difficult to maintain an accurate accounting of disturbed
areas and the associated sediment and erosion control measures in this SWPPP.
Additionally, most COPAD construction or other projects are required to comply with
Maricopa County fugitive dust requirements and the AZPDES Construction General
Permit No. AZG2008-001 (AZPDES CGP). Maricopa County requires that earth moving
projects greater than 1/10 acre obtain an earth-moving permit and implement a fugitive
dust control plan. As previously described, under AZPDES CGP, construction projects
greater than one (1) acre must prepare and file a Construction General Permit NOI and
implement a construction SWPPP.
