Plans). Additionally, parties are also considered operators if they have day to day operational control overactivities at a project which are necessary to ensure compliance with the SWPPP and/or other permitconditions (e.g., general contractor, erosion control contractor, and other subcontractors who are under thedirection of a Qualified SWPPP Practitioner).

The POLB will assist in obtaining coverage under the Construction General Permit by completing the NOI application which requires jurisdictional information and the required permit registration documents(PRDs). It is the responsibility of the developer/contractor to prepare and maintain a Storm WaterPollution Prevention Plan and to maintain a certified SWPPP Developer that complies with all therequirements herein. These documents must be submitted prior to the commencement of construction

activity. PRDs include: Notice of Intent (NOI) Site Map Risk Assessment Storm Water Pollution Prevention Plan (SWPPP) Post-Construction Water Balance Annual Fee Signed Certification Statement

Note: The POLB is responsible for submitting all documents to the State Board through the State Water Boards Storm Water Multi-Application and Report Tracking system (SMARTS system). This includesreceipt of the WDID number. The contractor should not submit any documents or supporting documents,including the SWPPP, to SMARTS.

1.1.1 Notice of IntentTo obtain coverage under the Construction General Permit, the site owner (POLB) must submit a Noticeof Intent (NOI) to the SWRCB. The contractor should not submit a NOI to the SWRCB. The NOI is anelectronic form that provides the SWRCB with information regarding the construction project, such as:

property owner developer or general contractor construction site address and other characteristics applicable local ordinances, if any receiving water for discharges vicinity map

1.1.2 Site MapThe project site map(s) are provided in Appendix B. The site map requirements are summarized inSection 2.0 of this SWPPP.

1.1.3 Risk AssessmentThe Construction General Permit establishes two types of construction sites (general and linear utility)

Department, this SWPPP template may be used for (LUP) though may require modification prior to use.Risk Level 3 general construction projects and active treatment systems are beyond the scope of thisdocument.

1.1.5 Post-Construction Water Balance SpreadsheetThe Construction General Permit requires projects to replicate the pre-project runoff water balancethrough post-construction non-structural and structural solutions. The Construction General Permit runoffreduction requirements will be fulfilled by the Port of Long Beach Standard Urban StormwaterManagement Plan (SUSMP). Thus, the Water Balance Spreadsheet does not need to be completed and theSUSMP should be referenced.

1.1.6 Annual FeeThe annual fee for stormwater permits is established through the State of California Code of Regulationsand based on the total area of land to be disturbed. The Port of Long Beach is responsible for all feesassociated with Port projects.

1.1.7 Compliance Certification

1.1.7.1 Electronic Signature and Certification RequirementsAll reports, certifications or other information required by the Construction General Permit must beelectronically signed, certified, and submitted via the State Water Boards Storm Water Multi-Applicationand Report Tracking system (SMARTS system) or to the State Water Board by the following:

2.0 S ITE DESCRIPTION

This SWPPP was prepared for construction activities at Pier T Berths T132-T140 located in the Port ofLong Beach (POLB). The Ryan Company will retrofit Pier T with a Shore to Ship Power system acrossapproximately 60 acres. The project will include the construction of a 25kV Switchgear, four Shore toShip Power (SSP) Substations, eleven Shore to Ship Power Outlets (SPO) and new fiber optic cables forPowerlogic communications between (SSP) Substations, Switchgear and the Admin Building.

The terminal site is located within the city limits of Long Beach, Los Angeles County, California at 301

Hanjin Road. Access for ships to the Pier T wharf will be provided through Long Beach Channel intoMiddle harbor and the West Basin. The Pier T container terminal will be accessed from Ocean Blvd,Interstate 710, and Pier T Ave. The project will be constructed in four phases, starting from the northeast

portion of Pier T Container Terminal and moving southwest towards the wharf and West Basin.

Vicinity maps for the construction project site are provided in Appendix B. These maps depict the Project

site in relation to the POLB complex.

In addition, the contractors will develop and update site specific maps and/or construction drawingsdepicting the following information. These maps will be kept on site and will be available to the RegionalBoard upon request.

2.1 EXISTINGSITECONDITIONS Previously, the project site was a United States Naval Station and Shipyard on Pier T in the Port of LongBeach. Pier T is approximately 325 acres in its entirety, of which Approximately 60 acres will be used toconstruct the Shore to Ship Power System. The entire site is currently paved with asphaltic concrete over amiscellaneous crushed base. There is no vegetation on the site. Surface elevations ranging across the siteare relatively flat sloping gradually from the north to the south at 1% with a mean elevation of 10-15above sea level. The subsurface soils consist of natural alluvial soils overlaid by hydraulically-placed filland conventionally placed compacted fill. There is approximately a 5 to 10-foot-thick layer of compacted

silty sand fill located below the pavement section. The materials below the fill generally consist of loose tomedium-dense silty sands and poorly graded sands at nearly elevation (-20) feet, below that, a firm to veryhard silt layer was interbedded with sandy soils. The standard penetration test (SPT) blow counts for theupper 30 feet (excluding the compacted fill) varied from 1 to 20 blows per foot. Most of the subsurfacesoils were classified as very loose to medium dense. The water table was recorded at an average of 10

below the surface.


18/335


2.3 RISK ASSESSMENT The Construction General Permit establishes two types of construction sites in California: generalconstruction, and linear underground and overhead utilities. General construction projects are classifiedwith up to three levels of risk. Risk assessment will not be conducted on LUPs using this SWPPPtemplate.

Risk, type, and applicability to the Harbor District are defined below. This SWPPP template has beentailored for Risk Level 1 and Risk Level 2 general construction projects. Risk Level 3 generalconstruction projects and active treatment systems are not anticipated within the jurisdiction of the HarborDistrict and therefore are considered to be outside the scope of this SWPPP template document.

Using the Standard Risk Assessment worksheet in Appendix C, this project has been designated: Risk Level 1

2.3.1 General Construction RiskRisk is calculated in two parts: 1) Project Sediment Risk, and 2) Receiving Water Risk. The HarborDistrict under the jurisdiction of the Port of Long Beach does not currently discharge stormwater directlyto waterbodies listed on the 303(d) List as impaired for sediment/siltation or turbidity. The HarborDistrict does not drain to waters designated with beneficial uses of SPAWN, COLD, and MIGRATORYand therefore has been designated a Low risk to water quality. Based on these circumstances, generalconstruction projects within the Harbor District are only designated Risk Level 1 or Risk Level 2. ThisSWPPP template has been tailored for Risk Level 1 and Risk Level 2 projects.

RISK LEVEL 1Risk Level 1 projects typically do not have a high potential to impact stormwater quality because:

1) These projects are normally constructed over a short period of time, minimizing the duration that pollutants could potentially be exposed to rainfall.

2) Occur on relatively flat sites with minimal opportunity for runoff and soils that provide highinfiltration rate.

RISK LEVEL 2Risk Level 2 projects can have a combination of High, Medium, or Low project sediment risk along withHigh or Low receiving water risk. These projects have a higher potential to impact water quality thanRisk Level 1 projects because they:

1) Occur over a longer period of time, potentially exposing disturbed areas to multiple rain events.2) Sites may include slopes or be located on soils that provide little or no infiltration.

2.3.2 Active Treatment SystemThere are instances on construction sites where traditional erosion and sediment controls do noteffectively control accelerated erosion. The use of an active treatment system may be necessary wherestormwater discharges leaving a project site may cause or contribute to an exceedance of a water qualitystandard The topography of the Harbor District area is relatively flat and unlikely to have accelerated

2.4 PROPOSEDCONSTRUCTION ACTIVITIES

The Pier T, Berths 132-140 Shore to Shit Power Project will be constructed in (4) Phases spanningapproximately (60) Acres.

Phase one is approximately (34) Acres starting in the northern portion of the site bordering Gerald Desmond Bridgecontinuing south ending at Pier T Berth 140. Phase (1) will involve the following construction Activities:

1,150 LF of (8) way ductbank 25kV switchgear, Ship to Shore Power Substation (SSP1), (2) shore to ship power outlets 9,200 LF of cable pulling through existing ductbank.

Excavation in this phase will produce approximately 2,439 CYDs of material that will be reused as fill.

Phase two is approximately (8) Acres contained entirely at Pier T Berth 138. Phase (2) will involve the followingconstruction Activities:

700 LF of (8) way ductbank Ship to Shore Power Substation (SSP2) (3) shore to ship power outlets 1,150 LF of cable pulling through existing ductbank.


Phase three is approximately (6) Acres contained entirely at Pier T Berth 136. Phase (3) will involve the followingconstruction Activities:

800 LF of (8) way ductbank Ship to Shore Power Substation (SSP3) (2) shore to ship power outlets 1,150 LF of cable pulling through existing ductbank.


Phase four is approximately (14) Acres contained entirely at Pier T Berth 132/134. Phase (4) will involve thefollowing construction Activities:

1,800 LF of (8) way ductbank Ship to Shore Power Substation (SSP4) (4) shore to ship power outlets 2,500 LF of cable pulling through existing ductbank.


Project site grading will occur on approximately 3% percent of the total site. This grading includes bothcut and fill. The total graded material is estimated to be 9,500 cubic yards. Graded materials are expectedto be balanced on site. If excess fill is encountered the soils will be hauled off site.

3.0 BEST M A NA GEMENTP RACTICES

This section contains a series of BMPs to eliminate or reduce pollutants in stormwater runoff from the project site during construction. The Construction General Permit prohibits the discharge of stormwaterthat causes or threatens to cause pollution, contamination or nuisance. It also allows the developer/ownerto choose the most economical, effective, and possibly innovative BMPs to reduce or eliminate pollutantsin runoff. These Construction General Permit requirements must be met, not only during the wet season,

but also on a year-round basis. The SWPPP must be implemented in a proactive manner during allseasons until the construction project is complete. This SWPPP template references the CaliforniaStormwater Quality Associations 2009 Construction BMP Guidance Handbook. This information may

be obtained from the CASQA website, http://www.cabmphandbooks.com/ , or by contacting CASQAdirectly at 650.366.1042 or [email protected].

3.1 GOODSITEM ANAGEMENT HOUSEKEEPINGGood site management and housekeeping measures are designed to reduce or eliminate the addition of

pollutants to construction site runoff through an analysis of pollutant sources and implementation of proper handling/disposal practices, employee education, and other actions. All projects shall implementgood site management/housekeeping measures to minimize or prevent pollutants in stormwater

discharges and authorized non-stormwater discharges. Good site management and housekeepingmeasures required for each risk level and type of construction project, and additional recommendedmeasures, are defined below.

3.1.1 Construction MaterialsAll Risk Level 1 or Risk Level 2 projects shall, at a minimum, implement the five mandatory measuresfor construction materials described below to prevent the discharge of construction materials that could

ResponsePlan for

Minor Spills

If a spill were to occur at the site, it will never be cleaned by hosing off thearea. Dry material spills will never be hosed down or buried.Minor spills that may occur will be controlled as follows:

1. The site construction manager or his designated representative will benotified immediately.

2. The spilled material will be identified and the approximate quantitywill be estimated.

3. The spread of the spill will be contained using absorbent material or barriers.

4. If the spill has occurred on a paved/impermeable surface, it will becleaned up using dry methods (absorbent materials, cat litter, and/orrags). Encircling it with absorbent materials will contain the spill. If

the spilled material is hazardous, then the used cleanup materials arealso hazardous and will be sent to either a certified laundry (rags) ordisposed of as hazardous waste.

5. If the spill has occurred on an unpaved or permeable surface,constructing an earthen dike will immediately contain the spill. Thecontaminated soil will be excavated and properly disposed of.

6. If the spill has occurred during a rain event, the area will be coveredas quickly as possible. The spill will be cleaned up as soon as possibleafter cessation of rain.


Spill cleanup materials will be stored near potential spill areas (e.g., paintingand vehicle maintenance areas).

3.2 NON-STORMWATERM ANAGEMENT The elimination or reduction of non-stormwater discharges to the storm drain system or receiving watersis a major goal of the Construction General Permit. Non-stormwater discharges to the storm drain systemand receiving waters should be eliminated to the greatest extent possible. Non-stormwater discharges can

be either direct discharges (e.g., pumped contaminated groundwater) or can result from dumping,washing, spills or leakage from storage tanks or transfer areas. To the greatest extent possible, the SiteOperator will operate a dry construction site .

X The streets will be cleaned in such a manner as to preventunauthorized non-stormwater discharges from reachingsurface water or MS4 drainage systems.


3.3 EROSION ANDSEDIMENTCONTROLS The Construction General Permit identifies erosion control BMPs as the primary means of preventingstormwater contamination. Particular attention must be paid to large, mass-graded sites where the

potential for soil exposure to the erosive effects of rainfall and wind is great and where there is potentialfor significant sediment discharge from the site to surface waters. As a rule, native vegetation inundisturbed areas represents the baseline for erosion control. Thus, retaining native vegetation inundisturbed areas provides the first and best line of defense against erosion and sedimentation, and at theleast cost to the contractor. Where this retention of native vegetation is not possible, the ConstructionGeneral Permit requires that stabilization be employed as soon as possible in critical areas. Sedimentcontrol BMPs should be the secondary means of preventing stormwater contamination. When erosioncontrol techniques are ineffective, sediment control techniques should be used to capture any soil that

becomes eroded.

The minimum erosion control and site stabilization measures that shall be implemented by projects ofvarying risk level and/or project type are summarized below.

3.5 POST-CONSTRUCTIONSTORMWATERM ANAGEMENTMEASURES& PLAN The provisions of this section shall take effect three years from the adoption date of the ConstructionGeneral Permit, on September 2, 2012.

The Construction General Permit aims to match post-construction runoff to pre-construction runoff.Projects located within the Harbor District of the Port of Long Beach are subject to the SUSMP post-construction requirements per Subsection 1.1.5.

Post-construction BMPs consist of permanent features and operational practices designed or implementedto minimize the discharge of pollutants in stormwater or non-stormwater flows from the site onceconstruction is completed and the facility is operational. Proper operation and maintenance is importantfor permanent structural BMPs so that they continue to function as designed. This is especially importantfor treatment controls (e.g., on-site retention or detention basins, vegetated swales, catch basin filters, orinserts), since their routine maintenance involves activities such as sediment removal, vegetationmanagement, and replacement of filters or inserts.

In order for construction to be found complete, the project shall meet all requirements outlined inSubsection 1.6 of this SWPPP, and shall:

Implement BMPs to reduce pollutants in stormwater discharges that are reasonably foreseeableafter all construction phases have been completed at the site. Post-construction BMPs shall beinstalled on site in accordance with the SUSMP new and re-development post-constructiont d d

Retention basin(s) shall be cleaned of accumulated sediment when sedimentreaches 10% of the basin capacity. Removed sediment shall be properlytransferred to a temporary soil storage area.

Maintenanceand Repair Silt fences shall be inspected and sediment removed before the accumulationis one-third the height of the fabric. Tears, overtopped areas, or broken fabricattachment to posts shall be replaced or repaired immediately.


Hay/straw bale dikes shall be replaced when strings break. Each bale shallhave two stakes. Firm contact shall be maintained between adjacent bales.

X Maintenanceand Repair

Storm drain inlet protections shall be inspected weekly and after each rainevent to ensure no clogging has occurred. Replace clogged filter fabric orstone filters immediately. Remove accumulated sediment behind the filerwhen depth exceeds half the height of the filter.


Diversion ditches and swales shall be maintained at the required depth.Settled sediment will be removed.


Stabilized construction entrances/exits shall be inspected for the transport ofsediment onto public rights-of-way before and after each rainfall.Stone/gravel material shall be replaced when surface voids are visible.C i h ll b d d k h l f

Temporary stone filter dikes will be inspected and replaced when sedimentimpedes the effective functioning of the device.


For temporary and permanent seeding used to stabilize exposed areas, theseeding will be inspected weekly during its period of establishment for barespots and areas of insufficient germination or growth. Remedial action will

be taken to establish surface cover in these areas once identified.Maintenanceand Repair

If seeding is not used to stabilize exposed areas, a stabilizing layer of gravelwill be placed.


Maintenance of waste management BMPs includes daily collection of sitetrash, inspection of the construction site waste area before and after rainevents, and arranging for regular waste collection.


The concrete truck washout drainage collection pit will be regularlymaintained to ensure adequate capacity to contain wash water and preventoverflow.


Maintenance of truck wheel washing shall include inspection of accumulatedsediment in the drainage pit (to be cleaned when accumulated sedimentreaches 10% of capacity) before and after rain events and berm repair asneeded.

X Maintenanceand Repair The covered material storage area shall be kept clean and organized.

The SWPPP must include procedures to ensure that all personnel implement the SWPPP and that trained personnel perform the inspections. When properly trained, site personnel are more capable of managingmaterials properly, preventing spills, and implementing BMPs efficiently and correctly. Personnel at alllevels shall be trained in the components and goals of the Construction General Permit. Specifically,employees of the Contractor and any subcontractors working on the construction site shall be informed ofthe goals of the SWPPP at a training meeting prior to commencing construction activities. The trainingmeeting shall cover basic stormwater information as well as the specific requirements of the ConstructionGeneral Permit. Specifically, the meeting will focus on implementation, inspection, and maintenance ofstormwater BMPs. Employees responsible for implementing, inspecting, maintaining, or repairingstormwater BMPs will receive copies of relevant portions of the SWPPP.

A Qualified SWPPP Practitioner (e.g., Construction Environmental Coordinator) shall train all newemployees and subcontractors before they will be permitted to work on the site. For projects that startduring the dry season, refresher sessions on stormwater pollution control will be conducted prior to thewet se
