Opinion for the Court filed by Circuit Judge SENTELLE.
National Committee for the New River, Inc. (“NCNR”), petitions for review of seven Federal Energy Regulatory Commission (“FERC”) orders denying an assortment of legal claims. Because we lack jurisdiction, we dismiss the petitions for review.
I.
In 2001, East Tennessee Natural Gas Company (“East Tennessee”) petitioned FERC for permission to extend its Tennessee-based natural gas pipeline about 94 miles from Virginia to North Carolina.
The conditions involve a range of arcana related to construction of the pipeline. For example, Condition 36 requires East Tennessee to minimize the Project’s impact on the southern population of the bog turtle. Condition 43 sets a 10-day deadline for cleanup after the backfilling of trenches. Other conditions require East Tennessee to file certain documents with FERC. Condition 8, for example, provides that East Tennessee must file weekly status reports with FERC until all construction activities are complete. And Condition 5, central to this case, sets forth the terms under which East Tennessee may realign the pipeline’s route during the course of its construction. See id. at 61,-765.
NCNR is an environmental group devoted to protecting the New River, which travels northward from North Carolina through southwest Virginia. NCNR fought the initial certification as an intervenor and lost. FERC denied a request for stay and rehearing,
Certification and the project’s completion did not deter NCNR from mounting further legal challenges against East Tennessee. NCNR filed almost 20 adversarial pleadings after the project was certified. This particular appeal concerns seven FERC orders addressing five legal issues arising from those pleadings. For the most part, the issues boil down to claims' that East Tennessee failed to live up to the conditions of certification. We discuss each in turn, though only the first merits more than cursory analysis.
II.
NCNR’s primary claim, the subject of four FERC Orders and two rehearings, is that East Tennessee’s route realignments were unauthorized because they deviated *832 too far from the route FERC certified. FERC maintains that it had approved the realignments as garden-variety changes, often at the behest of landowners. .NCNR argues that East Tennessee moved the pipeline so far in spots that it no longer resembles the route originally approved. At the very least, NCNR wants this Court to remand the matter to FERC, which might then order East Tennessee to conduct new environmental impact studies for the realigned routes.
We do not evaluate the realignments on the merits because we hold that NCNR lacks standing to bring this challenge.

Aesthetic and environmental harms may confer Article III standing if they describe a concrete and particularized injury in fact that is actual or imminent, causally linked to the conduct at issue, and redressable by the relief requested.
See Lujan v. Defenders of Wildlife,
NCNR submitted five affidavits describing the harms its members would suffer if a pipeline were constructed under and around the New River. The affidavits recount manifold environmental injuries, including impacts from soil erosion and blasting during construction, scars on the landscape, and water pollution. They also portray aesthetic harms such as degradation of the viewshed, decreased pleasure from swimming and fishing in the river, and lessened enjoyment picnicking and hiking near it. These harms mirror those deemed sufficient in
Friends of the Earth, Inc. v. Laidlaw Envtl. Servs., Inc.,
These allegations are no longer sufficient on the present record. All five affidavits focus on the general harms that would arise from the construction of a natural gas pipeline under and across the New River. But NCNR already lost that battle when this Court upheld FERC’s certification of the pipeline.
See New River,
A further consequence of this failure to plead particularized injury arising from the route realignments is that the injuries discussed in the affidavits are not redress-able by the relief requested.
Cf. Allen v. Wright,
Beyond the route realignments, NCNR raises four additional issues. The first is whether East Tennessee’s successful effort to drill under the New River two years ago *833 should, have been declared a “failure.” We assume NCNR is referring to Condition 22 of-the Certification, 2 a safety-valve allowing East Tennessee to abort an ill-executed drilling effort in order to find a new spot more amenable to drilling. This Condition confers no rights upon NCNR. Moreover, since the pipeline has been operational for over two years, we hold that the issue is moot: Having succeeded, the drilling effort patently was not a failure.
The next issue is procedural in nature. NCNR argues that it was entitled to service of documents by East Tennessee after certification. “[I]n eases in which a party
has been accorded a procedural right
to protect his concrete interests, the primary focus of the standing inquiry is not the imminence or redressability of the injury to the plaintiff, but whether a plaintiff who has suffered personal and particularized injury has sued a defendant who caused that injury.”
Fla. Audubon Soc’y v. Bentsen,
Next, NCNR raises another procedural claim to which it has no entitlement. It argues that FERC’s November 14 Order was invalid because it was signed by the Deputy Director of the Office of Energy Projects, not the Director himself. This claim is frivolous. As FERC explained, the Director could — and did — delegate signing responsibility to his deputy and designee. FERC regulations state: “Where the Commission, in delegating functions to specified Commission officials, permits an official to further delegate those functions to a designee of such official,
designee shall mean the deputy of such official,
the head of a division, or a comparable official as designated by the official to whom the direct delegation is made.” 18 C.F.R. § 375.301(b) (emphasis added). Even assuming NCNR had a procedural right in this case, it has not shown a “substantial probability” that the agency’s action “created a demonstrable risk, or caused a demonstrable increase in an existing risk, of injury to the particularized interests of the plaintiff.”
Fla. Audubon,
Finally, NCNR appeals a FERC order rejecting the claim that East Tennessee failed to consider a particular route alternative.

III.
For the reasons set forth above, NCNR’s petitions for review are dismissed.
So ordered.
Notes
. Because we decide this issue on standing grounds, we do not reach mootness.
. That Condition provides:
If East Tennessee cannot successfully use [horizontal directional drilling] at the proposed crossing of the New River and the New River Trail State Park, East Tennessee shall provide an analysis of rerouting the pipeline across the New River at a location where geotechnical investigations indicate [the drilling] will be more feasible....
. This Circuit has described res judicata as having "a some what jurisdictional character.”
