Northern Dynasty: US Army Corps of Engineers' Claim That Economic Costs of Pebble Project Outweigh Project Benefits Contradicts the Administrative Record

Northern Dynasty Minerals Ltd. (TSX:NDM)(NYSE American:NAK) ("Northern Dynasty" or the "Company") reports that its Request for Appeal ("RFA") of a federal permitting decision concerning Alaska's Pebble Project challenges key conclusions reached by the US Army Corps of Engineers ("USACE") with respect to the project's economic benefits and costs

Prepared and submitted by the Company's 100%-owned US-based subsidiary Pebble Limited Partnership (the "Pebble Partnership"), the RFA asserts that the USACE's Public Interest Review ("PIR") for the Pebble Project, published coincident with its Record of Decision ("ROD") in November 2020, is contrary to the law and inconsistent with the record - including the Final Environmental Impact Statement ("EIS" or "FEIS"). The Pebble Partnership believes the social and economic impact conclusions drawn by the USACE in the PIR give "undue weight to speculative harms not supported by the record while giving little weight to the Project's undisputed benefits to local communities, the region, and the State." (RFA p. 3)

The USACE accepted the Pebble Partnership's RFA last month, and has appointed a Review Officer to oversee the administrative appeal process. While federal guidelines suggest the appeal should conclude within 90 days, the USACE has indicated the complexity of issues and volume of materials associated with Pebble's case means the review will likely take additional time.

Pebble asserts USACE findings are unsubstantiated

The Pebble Partnership's RFA asserts that ‘economic detriments' associated with Pebble as cited by the USACE are vague and speculative, whereas the significant, long-term socioeconomic benefits of the project for local communities, the region, the state and the nation are well documented in the FEIS.

The FEIS documents a broad range of regional and statewide benefits associated with Pebble, including:

• direct and indirect employment in local communities, which currently face a dearth of full-time, year-round, well-paid jobs;
• reduced transportation and energy costs in a region that currently faces one of the highest costs of living in the nation;
• beneficial economic effects on minority and low-income communities;
• potential to offset the current high rate of outmigration in southwest Alaska, as residents leave in search of economic opportunities elsewhere;
• hundreds of millions of dollars in government revenues over the life of the project, with potential corresponding state and local spending on health, education and other valued public services.

"In sum, the record demonstrates the significant, long-term socioeconomic benefits of the Project to local communities, including jobs, infrastructure, health, education and decreased cost of living. Nonetheless, the ROD outrageously asserts that there are adverse economic effects that would outweigh the benefits at the local and regional level. The District relies on pure conjecture to support this finding." (RFA p. 38)

PLP asserts that ROD findings on ‘subsistence' contradict FEIS

Among the ‘economic detriments' the USACE cites is that development of the Pebble Project could lead to less subsistence activity in local communities, resulting in less ‘wild food' for local residents. The Pebble Partnership RFA argues that this conclusion is contrary to experience at other Alaska mines, where work rotations permit local employees to participate in traditional in-season subsistence activities, as well as FEIS findings that indicate Pebble will have no effect on the availability of subsistence fish and wildlife resources.

The RFA asserts that the USACE's ROD statements about potential detrimental project effects on subsistence are pure conjecture, and are directly contradicted by the FEIS, which cites an extensive subsistence study undertaken in the Pebble Project area.

USACE in Pebble Project ROD: "If high-harvesting members of the community find project-related employment and have less time for subsistence activities, the rest of the community and households in other communities could end up receiving less wild food through sharing and trading relationships. Increased employment of adults in the communities could impede the amount of time spent teaching young people to hunt, fish, gather, process, and preserve subsistence resources which would impact the amount and quality of traditional knowledge passed on to younger generations, potentially resulting in a long-term or permanent adverse effect to communities." (RFA p. 38)

USACE in Pebble Project FEIS: "The effect of income on subsistence success (i.e., subsistence production) is evident among households with unique demographic structures. The magnitude of the effect of income is such that in many communities, 30 percent of households produce 70 percent of the subsistence harvest. These "super households" are distinguished because they include multiple working-age males, tend to have high incomes, and often are involved in commercial fishing. These three factors support high-producing households to be able to combine subsistence activities with paid employment and to arrange considerable labor in flexible ways that maximize harvests of subsistence foods, which are then shared with other households in the community and region. " (RFA p. 40)

Pebble Partnership RFA: "Local community members can make their own decisions as to how to best meet subsistence and other community needs, including whether to pursue mine employment in the first place. The idea that it is a detriment to have a project that offers employment because jobs could change the local way of life is an insult to the adaptability of the local communities." (p. 40)

PLP asserts post-closure ‘economic detriments' are actually baseline conditions

Many of the ‘economic detriments' the USACE cites are, in the Pebble Partnership's view, changes that could occur after the proposed Pebble mine concludes operations. For instance, the ROD asserts that post-closure "some residents may move to find new employment" and "some decreases of cost of living may increase to pre-project levels." The USACE also suggests local residents who have gotten used to steady income from Pebble-related employment and economic activity may have to adjust their lifestyles.

The Pebble Partnership's RFA objects to the USACE's conclusion about post-closure ‘economic detriments' on multiple grounds, including that they are not supported by the record.

"The implication being that locals would be better off never having the jobs and associated benefits in the first place so that they do not have to ‘adjust' when the jobs go away. This conjecture has no support in the record. It also unfairly assumes local communities are unable to save, invest, and otherwise plan for such economic change. The FEIS, by contrast, recognizes that local communities could use the Project revenue to make long-term improvements, including to community infrastructure and community health care facilities." (RFA p. 39)

"…even if these impacts occur, the District does not explain why these are "detriments" caused by the Project as opposed to a return to baseline conditions. If the 20+ years of mine-related employment gives the local community greater economic stability, reduces out-migration, and lowers the cost of living for two decades - isn't that still an economic benefit even if the conditions return to baseline after closure? Moreover, the assumption that all socioeconomic benefits would return to pre-project levels (or worse) is nowhere supported in the record." (RFA p. 39)
