PLP Overview

CONCERNS AND ISSUES
The Pebble Project

✷ Pebble Mine will impact a $1.5 billion commercial fishing industry and the 14,000 jobs involved.

✷ The mine will impact the legendary salmon runs that have supported the Bristol Bay community for thousands of years.

✷ Many miles of pristine valleys and salmon streams will be turned into an open pit, waste piles, and mine works that will turn the area into an INDUSTRIAL ZONE.

  • PERMIT APPLICATION IS INCOMPLETE
  • NOBASELINE INFORMATIONINCLUDED IN THE PERMIT FOR SOME OF THE MAJOR COMPONENTS OF THE MINE INCLUDING:
    • NATURAL GAS PIPELINE ACROSS COOK INLET
    • SOUTH ACCESS ROAD FROM KOKHANOK TO AMAKDEDORI
    • 270 MW POWER PLANT
    • ILIAMNA LAKE FERRY CROSSING AND PIPELINE
    • DEEP WATER PORT AT AMAKDEDORI
  • NO ECONOMIC FEASIBILITY STUDY THAT SHOWS THE MINE PLAN IS ECONOMICALLY VIABLE

PLP Mine Plan

CONCERNS AND ISSUES
Mining & Processing

  • HOW MUCH WATER WILL BE REQUIRED FOR PROCESSING ORE?
  • WHAT CHEMICALS WILL BE USED AND HOW TOXIC ARE THEY?
  • WHAT STREAMS WILL HAVE WATER DIVERTED TO THE MINE?
    • Potentially up to 35 billion gallons/year
  • EIS NEEDS TO INCLUDE BUILD-OUT SCENARIOS FOR A 20+ YEAR MINING OPERATION DUE TO THE KNOWN 11 BILLION TONS OF MINERAL RESOURCES
  • ACID MINE DRAINAGE FROM WASTE ROCK WILL BE GENERATED AND CAN HARM THE STREAMS AND WETLANDS IN THE AREA
  • MINING OPERATION WILL HAVE SIGNIFICANT IMPACTS IN THE AREA DUE TO TRUCK TRAFFIC, NOISE FROM BLASTING, DUST IMPACTS, AND AIR QUALITY FROM POWER PLANT

PLP Tailings Plan

CONCERNS AND ISSUES
Tailings Storage

  • PERPETUAL STORAGE OF ACID GENERATING TAILINGS BEHIND EARTHEN DAMS IS PROBABLY THE SINGLE GREATEST HAZARD POSED BY THIS PROJECT
  • TAILINGS STORAGE FACILITIES WILL BE UNLINED AREAS THAT WILL ALLOW TOXIC LEACHATE TO MIGRATE TO GROUNDWATER AND SURFACE WATER
  • HUGE DAM EMBANKMENTS OVER 500 FEET HIGH WILL BLOCK AND INUNDATE SALMON STREAMS AND TRIBUTARIES IN THE NORTH FORK KOKTULI

PLP Water Management Plan

CONCERNS AND ISSUES
Water Management

  • NO WATER MANAGEMENT PLAN PROVIDED IN 404 APPLICATION TO THE USACE
  • HOW MUCH WATER WILL BE NEEDED FOR MINE OPERATIONS?
  • SIGNIFICANT IMPACTS WILL OCCUR BY DIVERTING WATER FROM SALMON STREAMS FOR MINE OPERATIONS
    • Stream impacts will occur during summer salmon spawning and rearing periods & during winter when salmon are over-wintering and eggs are incubating in these streams
  • SIGNIFICANT IMPACTS WILL OCCUR DOWNSTREAM OF THE MINE FROM WATER BEING DISCHARGED WITH DIFFERENT TEMPERATURES, WATER CHEMISTRY, AND FLOW RATES THAN THE NATURAL CONDITIONS IN THE HEADWATER STREAMS
  • SIGNIFICANT IMPACTS TO GROUNDWATER AND SURFACE WATER CAUSED BY DEWATERING OF THE OPEN PIT

PLP Power Plan

CONCERNS AND ISSUES
Power Generation

  • POWER PLANT EMISSIONS WILL INCLUDE HEAVY METALS, PARTICULATE MATTER, AND TONS OF CO2
  • IMPACTS TO RAIL BELT NATURAL GAS SUPPLIES CAUSED BY THE 270 MW POWER PLANT NEED TO BE IDENTIFIED IN EIS
    • The Pebble Power Plant is BIGGER than Anchorage’s South Central Power Plant
  • INCREASED RISKS OF FUEL SPILLS IN COOK INLET, ILIAMNA LAKE, AND ALONG THE ENTIRE PIPELINE CORRIDOR THAT WILL CROSS HUNDREDS OF SALMON STREAMS, PONDS, WETLANDS, AND SUBSISTENCE AREAS

PLP Roads & Transport Plan

CONCERNS AND ISSUES
Roads & Transport

ROADS WILL CROSS MANY SALMON STREAMS, WETLANDS, AND SUBSISTENCE AREAS

  • OVER 200 CULVERTS WILL IMPACT FISH PASSAGE. CULVERTS NEED TO BE ‘FISH FRIENDLY’
  • NO FISH SURVEYS TO IDENTIFY SALMON STREAMS HAVE BEEN PROVIDED FOR THE SOUTH ACCESS ROAD
  • OVER 1,000 ACRES OF WETLANDS WILL BE IMPACTED BY ROADS
  • INCREASES IN NOISE, DUST, AND TRAFFIC
  • HABITAT FRAGMENTATION WILL OCCUR DUE TO ROADS CROSSING MIGRATION CORRIDORS

PLP Ferry Plan

CONCERNS AND ISSUES
Iliamna Lake Ferry & Terminals

  • NO BASELINE DATA PROVIDED FOR FERRY CROSSING AND PIPELINE ON THE BED OF ILIAMNA LAKE WHICH IS THE WORLD’S LARGEST NURSERY FOR SOCKEYE SALMON
    • Millions of salmon fry live in Iliamna Lake
    • The Kvichak watershed has produced more salmon than any other system in Bristol Bay
  • FERRY ROUTE BETWEEN NEWHALEN AND KOKHANOK WILL IMPACT FRESHWATER SEALS HABITAT
  • INCREASED BOAT TRAFFIC ON ILIAMNA LAKE AND IMPACTS CAUSED BY ICE-BREAKER ON THE LAKE FOR SAFE WINTER TRAVEL BY LOCAL SNOWMACHINE TRAFFIC
  • INCREASED RISK OF FUEL AND CHEMICAL SPILLS IN THE LAKE AND AT THE FERRY TERMINALS
    • A spill in Iliamna Lake could wipe out 2 generations of salmon

PLP Port Plan

CONCERNS AND ISSUES
Amakdedori Port

  • CONSTRUCTION OF AN INDUSTRIALIZED PORT WILL IMPACT NEAR SHORE ENVIRONMENTS
  • PORT IS LOCATED IN CRITICAL HABITAT FOR BELUGA WHALES AND NORTHERN SEA OTTERS
  • PORT IS VERY NEAR THE MCNEIL RIVER STATE GAME SANCTUARY AND REFUGE
    • Amakdedori has a high concentration of brown bears
    • NO BASELINE DATA provided for marine or terrestrial animals at Amakdedori
  • HIGH TIDES, STRONG CURRENTS, SHALLOW ROCKY SHOALS, AND HIGH SEAS WILL CAUSE SAFETY AND NAVIGATIONAL ISSUES FOR VESSELS AT THE PORT AND LIGHTERING ORE CONTAINERS TO LARGE BARGES OFFSHORE
  • BALLAST WATER FROM FOREIGN CONTAINER SHIPS WILL BRING INVASIVE SPECIES TO COOK INLET
    • Ore will be shipped to smelters in Asia
  • SIGNIFICANT IMPACTS TO KAMISHAK BAY DISTRICT SALMON FISHERY AND CRAB, HERRING, COD, HALIBUT FISHERIES

PLP Closure & Reclamation Plan

CONCERNS AND ISSUES
Closure & Reclamation

  • MAINTENANCE AND MONITORING OF THE TAILINGS STORAGE FACILITIES AND OPEN PIT WILL BE REQUIRED FOREVER DUE TO ITS TOXICITY
    • A lake filled with toxic metals will form when mining the open pit is completed and Pebble turns off the groundwater pumps used to dewater the pit
    • No mines requiring perpetual water treatment should be permitted in Alaska
  • SEEPAGE & LEACHATE MONITORING AND COLLECTION SYSTEMS AND THE WASTE WATER TREATMENT PLANT WILL NEED TO MAINTAINED FOR FOREVER
  • WATER WILL HAVE TO BE CAPTURED AND TREATED FOR HUNDREDS OF YEARS
  • WEATHERING OF EXPOSED WASTE ROCK AND PIT WALLS WILL PRODUCE ACID MINE DRAINAGE
  • THE MAINTENANCE AND MONITORING COSTS WILL BE HUGE AND WHO WILL TAKE CARE OF THIS ONCE NORTHERN DYNASTY WALKS AWAY?
  • A REALISTIC RECLAMATION AND CLOSURE PLAN IS NEEDED
