EPA Emission Rules Good for Environment

EPA, standing for The US Environmental Protection Agency, has released Clean Air Act standards to curb the emission of carbon pollution from new power plants. The Clean Air Act was the first major environmental law in the United States to include a provision for citizen suits. It was proposed to combat climate change and improve public health.

Power plants are the largest concentrated source of emissions inthe United States, together accounting for nearly 30% of all domestic green house gas emissions. Numerous state and local governments have enacted similar legislation to reduce carbon pollution. Advancements in testing andmonitoring have led to the discovery of many significant air pollutants since the initial establishment of six mandated criteria pollutants, including ozone,particulate matter, carbon monoxide, nitrogen oxides, sulfur dioxide, and lead. The National Resources Defence Council (NRDC) said the proposed rules were a"climate breakthrough”.

Albanese on Vedanta and Franco-Nevada boards

Former Rio Tinto CEO Tom Albanese has chalked up two appointments since departing the British-Australian company in January.

The American takes the nonexecutive chairperson role at Indian company Vedanta Resources Holdings and has been appointed to the board of Canadian gold royalties company Franco-Nevada Corporation.

Albanese brings his experience as former CEO and analysts believe he is likely to give clarity to Vedanta's message.

Albanese is the first of top-level mining chief executives who resigned as fortunes soured in mining to take up a new position.

He left Rio after six years when the group revealed a $14-billion write-down almost entirely on the value of his two most significant buys, the Alcan aluminium company, and the Riversdale coking coal company in Mozambique.

Vedanta has just completed an 18-month overhaul of its structure.

Vedanta Resources Holdings is 100% owned by Vedanta Resources plc.

Franco-Nevada, which has interests in large gold development and exploration projects, pays monthly dividends.

Shares in Northern Dynasty Minerals (TSX: NDM) nosedived 35% on Monday after the explorer's 50% partner in the Pebble project, potentially the world's richest copper-gold mine, bailed out.

World number four diversified miner Anglo American (LON: AAL) said Monday it is pulling out of  the project in the Bristol Bay region of Alaska and at the same time write off its 300 million investment.

Vancouver-based Northern Dynasty has vowed to continue with the project .

Under the partnership Anglo committed to staged investment of $1.5 billion to keep its half share.

With those funds off the table it is difficult to see  how Northern Dynasty – now worth $140 million in Toronto – could come up with estimated $80 million a year needed to advance the project to its earliest possible construction start date of end-2017.

The February 2011 preliminary assessment for Pebble saw capex requirements of just under $5 billion. Six-seven years on that's gonna look more like $7 billion.

That is if Pebble is permitted, also not a likely scenario any time soon.

Then again, in the words of Anglo CEO Mark Cutifani "Pebble is a deposit of rare magnitude and quality."

With average annual production estimates of more than 500 million pounds of copper, 660,000 oz of gold, 1.75 million oz of silver and 25 million pounds of molybdenum for the first 30 years (and the possibility to extend that to 78 years)  is Pebble  is just too rich a deposit not to pursue.

BHP opens coal mine in Queensland despite market challenges

BHP Billiton (ASX, LON, NYSE: BHP) and joint venture partner Mitsubishi officially opened Wednesday their new $1.4 billion Daunia coking coal mine in central Queensland, defying the challenging conditions that currently affect the market for steel making coal.

Prices for the fuel used to make steel have been hurting because of low demand and oversupply from rivals, but BHP Coal President, Dean Dalla Valle, seemed optimist, as he said the BHP Billiton Mitsubishi Alliance (BMA) produces “the world’s premium quality metallurgical coal.”

The opening of Daunia mine, which is expected to produce 4.5 million mt/year of metallurgical coal, is considered a step forward for the BHP Mitsubishi alliance in its quest to improve profitability across the division.

The partners have committed $7.7 billion for major projects in Queensland over the past three years, including the new Caval Ridge mine and the Hay Point Coal Terminal’s expansion, currently underway.

BHP is also working on completing the Broadmeadow mine extension before year-end and, in July, it cancelled the sale of its Gregory Crinum mine after making operational improvements.

Australia’s coal sector has been struggling under lower commodity prices, high costs, union disputes and even flooding in recent years. All factors that cost the alliance important market share.

However, CEO Andrew Mackenzie said last month that the metallurgical coal business has returned to profitability, thanks to several cost cutting measures.  A big part of them was achieved by dismissing mining contractors, applying efficiency measures and reducing in the number of days lost to strikes.

BHP’s combined coal business, headquartered in Brisbane, includes 20 operations around the world and a workforce of approximately 30,000 people.

Canadian Zinc Corporation (TSX:CZN)(OTCQB:CZICF) ("the Company" or "Canadian Zinc") is pleased to report a new diamond drill exploration program is set to commence at the Company's Prairie Creek Project, Northwest Territories.

Five drill holes totalling approximately 2,500 metres of coring are planned to test a large multi-stacked gravity and electromagnetic ("EM") geophysical anomaly that is estimated to be at a depth of between 200 and 450 metres below surface, situated approximately one kilometre from the mine site, outside but adjacent to the defined mineral resource. The drill rig is being mobilized to the first pad and drilling is expected to commence by the end of the week.

Alan Taylor, Vice President of Exploration and COO of Canadian Zinc stated, "The delineation at the end of last season of a new strong coincident EM and gravity geophysical anomaly adjacent to the defined deposit was particularly interesting and we are anxious to drill test it. The discovery of any resource in this area could have a significant impact on the economics of the existing project and future implications on additional property-wide exploration at Prairie Creek."

In 2012, a geophysical exploration program involving surface and downhole electromagnetic and surface gravity surveys was completed in the proximity of the Prairie Creek deposit. The results defined a strong multi-channel EM anomaly. A coincident gravity anomaly was also identified over the same area by a loose-grid gravity survey.

This 2013 drill program is fully supported by a recently completed $4 million flow-through financing which closed on August 20, 2013 (refer to Company news release of same date). The Company has mobilized one of its three surface diamond drill rigs to commence this program which will continue for the next two months.

Prairie Creek Mine Background

The Company's main project is the 100%-owned Prairie Creek zinc, silver and lead project located in the Northwest Territories, Canada. The Prairie Creek Project contains a Mineral Reserve of 5.2 million tonnes averaging 9.4% zinc, 9.5% lead and 151 g/t silver. In addition, Prairie Creek hosts an Inferred Resource of 6.2 million tonnes averaging 14.5% zinc, 11.5% lead, 0.57% copper and 229 g/t silver. (AMC Mining Consultants (Canada) Ltd. J M Shannon and D Nussipakynova, Qualified Persons, June 2012).

The Mackenzie Valley Land and Water Board (the "MVLWB") completed its regulatory process July 5, 2013 by finalizing a Type "A" Water Licence and subsequently forwarding it to the Minister of Aboriginal Affairs and Northern Development Canada with the recommendation that the Minister approve and sign the Licence. The MVLWB has previously issued three Land Use Permits and a Type "B" Water Licence to the Company for future operations.

Greens slam new assessment criteria for mine proposal

New assessment criteria for a proposed expansion of a Hunter Valley coal mine are being slammed as a declaration of war on local industries.

A review of plans for the Drayton South project near Muswellbrook is now before the Planning Assessment Commission after being stalled earlier this year on the back of public opposition.

But revised terms of reference have dumped key elements including the project's impact on health, amenities and infrastructure.

They've also dropped any mention of equine and viticulture critical industry clusters.

Greens mining spokesman Jeremy Buckingham says it's a slap in the face.

"The community, the thoroughbred breeders, they wanted expanded terms of reference, they wanted a higher bar for this mine to jump over if it was going to proceed and that is not what has happened," he said.

"So what's coming out of the department is just spin, the government is going to back the miners, Barry O'Farrell is backing the miners over the community, that's clear."

Mr Buckingham says it is a major step backward for the Hunter region.

"It's just a betrayal by Barry O'Farrell, it's clear that Chris Hartcher, the Minerals Council, the coal lobby have the ear of the government and they're putting their interests before the health and sustainability of other industries and communities in the Hunter Valley," he said.

The Planning Department says major progress on important assessment issues such as local health, amenity and infrastructure has been made since the review was delayed.

The department says the new terms of reference are revised to focus mainly on the project's impacts on the nearby Coolmore and Woodlands horse studs.

It says issues can be dealt with by the department which will then go back to the Planning Assessment Commission for a final decision.

Dredging – Key Factor for US Container Port Call Strategies

In advance of debate at the upcoming TOC Americas 2013 conference in Miami, Dr. Asaf Ashar argues that dredging may turn out to be the key factor driving long-term US container port call strategies on both Suez and Panama all-water services.

How will Panama Canal expansion impact shipping and port networks across the Americas? This has been a topic of intense debate over some years now and while there appears to be fairly widespread agreement on some issues, the jury is still very much out on others.

Where the maritime community seems to have reached a fair consensus is on the size of the ships that will be deployed on All-Water Asia/US East Coast (USEC) through Panama (AWP) services. Once the widened Canal opens, ship sizes are anticipated to increase quickly from the current average 4,500 TEU up to around 8,000 TEU – similar to the size of ships presently deployed on All-Water Suez (AWS) services. There is also general agreement that despite the considerable increase in ship size and the respective reduction in shipping costs, the AWP route is likely to see only a modest increase in market share relative to its main rivals, the AWS and the US West Coast (USWC) landbridge.

Where opinions start to diverge more sharply is on the impact of Canal expansion on carriers’ North American service patterns and, especially, whether the present approach based mainly on direct port calls will be replaced, at least in part, by a hub and spoke system.

Considering that the deployment of 8,000 TEU ships on AWS, which began in 2011, has so far had no impact at all on the prevailing direct service pattern, any change is not likely to be swift. A recent review of AWS rotations on the USEC indicates that they are still based on direct calls even at relatively small ports like Boston – handling 190,000 TEU a year – and at ports with relatively shallow channels like Savannah, GA, currently with 42ft alongside. It is reasonable to expect that the deployment of similar ships on the AWP will have a similar impact on service pattern – meaning no impact, at least initially.

But, the locks of the expanded Panama Canal are designed for New-Panamax (NPX) ships, which are forecast to initially have capacity of 13,500 TEU and eventually 15,000 TEU. Following worldwide trends, it is quite likely that NPX will be deployed on AWP as well as on AWS services within 5 years or so following the expansion. Interestingly, this possibility was considered unlikely in channel-deepening studies undertaken by the US Army Corps of Engineers, the Federal agency in charge of US ports’ channels. Accordingly, the design ship for these channels is just 8,000 TEU! The Corps also dismissed the possibility that in the longer term, ships bigger than NPX, such as the 18,000 TEU Maersk Triple-Es recently deployed on the Asia-Europe trade, could be used on AWS services; and that in the even longer future ship size may reach the 28,000 TEU Malacca-Max (MLX).

It is not unfeasible that that introduction of ships too large for USEC ports’ newly-dredged channels will trigger a change in the service pattern of both AWP and AWS to hub and spoke. In this case, USEC ports would find themselves served by feeder services based on foreign hubs in the Caribbean region for AWP and Canada for AWS. This change in service pattern could be avoided by further deepening of USEC ports’ channels. However, considering the arduous process of the recent deepening projects, the prospects for this happening look pretty dim.

If indeed the AW service pattern is transformed into hub and spoke, it is reasonable to assume that the AW feeders will call at smaller ports previously bypassed by direct AW services. The additional calls may have a limited impact on the traffic of ports with captive hinterland, such as NY; it may have a critical impact on ports like Miami, which have invested heavily in water, road and rail accesses hoping to be a first-in and last-out for AWP and capture a large share of southeastern US traffic. It will be interesting indeed to hear what the industry makes of these various issues when the various parties assemble in Miami this October.

Dr. Asaf Ashar is Research Professor with the US National Ports & Waterways Initiative (NPWI), and also an independent maritime and port consultant. Among many other activities, he has published over 50 academic papers, reports and theses, including the highly publicized series on The Fourth Revolution: Long-Terms Prospects of Liner Shipping, first published in 1999/2000 and recently revisited as the Revised Fourth Revolution, published in Port Technology, Journal of Commerce and World Cargo, between Sep 2012 and March 2013. Dr. Ashar will be chairing a round-table discussion on Panama vs. Suez and prospects for direct call vs. transhipment as part of the Big Industry Debate at TOC Container Supply Chain Americas 2013, on the afternoon of Tuesday 1 October.

TOC Container Supply Chain Americas 2013 runs 1-3 October at the MACC Miami. The 3-day event includes three conference streams – TOC Container Supply Chain, analysing regional container trade, shipping, ports and logistics; TOC Cold Chain, focused on perishable trade, cold chain logistics and refrigerated shipping, and TECH TOC, a free-to-attend operations and technology track for container port and terminal executives. An exhibition of port and terminal services, equipment and technology runs alongside, complemented by industry networking receptions and a Miami port logistics site visit on 31 September.

SeaBat Sonars Cut Survey Costs at Rotterdam

The Port of Rotterdam is an open deep-water port in the river estuary Maas, and this location of the port necessitates maintenance dredging due to siltation ’attacks’ from both tidal current and river discharge.

Siltation from the sea, coming in during the flood tide and how to build bitcoin mining eroded materials from the hinterland transported in the river flow results in a total of 6.000.000 m3 of maintenance dredging works in the port basins every year.

To control the dredging activities the Port of Rotterdam conducts hydrographic surveys on a daily basis. Two purpose built survey vessels are operated by the Asset Management department of Port of Rotterdam. The survey vessels are equipped with Teledyne RESON SeaBat multibeam echosounders (model 7101 and 7125), RTK GNSS positioning and silt density equipment (Silas-Odom CV2).

Challenge

Continuous multibeam surveys result in large data volumes and processing time. The goal of the Asset Management Department is to produce bathymetric products within one day after surveying. Products are:

- Bathymetric paper chart for vessel traffic management (VTM) and dredging operations;

- Electronic Navigation Chart (ENC) for portable pilot units (PPU);

- ASCII gridded data sets for dredging equipment and GIS analysis.

Shipping, berth occupancy, satellite blocking by cranes or container stock piles, sea water mixtures and fluid mud bottoms are a continuous threats to the quality and production rate of the bathymetric surveys. To save processing time the Asset Management Department try to keep up the ‘first time yield’ level. This process starts with high quality raw multibeam data input. Cleaning data filters will run faster and more accurate based on almost clean raw data obtained from the best available survey equipment.

Survey operations

Typical port hydrographic surveys contains locations with slopes, various bottom types and man-made constructions in a relatively small area requiring the use of an all-round multibeam echosounder system that provides:

- Wide beam coverage to get depth data as close as possible to water level on slopes;

- Single transducer head (complexity and data reduction);

- Excellent object detection;

- Variable pulse length settings to optimize acoustics for fluid mud bottoms;

- High update rate for survey speed up to 10 knots.

Side scan option

The SeaBat 7101 and SeaBat 7125 meets all the requirements mentioned above. The data quality is very good hence hardly any data cleaning is necessary post survey. The beam selection settings (to set area of interest) and system displays are features that make the systems particularly user friendly.

Results

Since the end of 2012 the Asset Management department of the Port of Rotterdam developed a range of efficiency efforts to reduce the need for survey personnel and equipment. These efforts resulted in a reduction of about half a survey vessel, representing a cost saving of approximately €150,000 per year; in part due to the upgrade of the multibeam systems to the Teledyne RESON products mentioned above.
