Conclusions:

In response to HED request (Carol Christensen on 12/ 21/ 01), the three major linuron metabolites * formed under aerobic soil conditions use on carrots in (EPA Reg. No. 1812 320) are represented by this memorandum. The degradate 3,4 dichloroaniline (3,4 DCA) was not included in this assessment. Based on the results from the aerobic soil metabolism study (MRID# 41625401), the degradate 3,4 DCA was not detected (0.01 ppm detection limit). According to acceptable fate studies, 3,4 DCA is formed under anaerobic aquatic conditions (conditions rarely found in the environment and/ or relevant to drinking water assessment) consisted of 1.5% of the applied linuron.

*:( 3( 3, 4 dichlorophenyl) 1 methoxyurea) (desmethoxy linuron), (3( 3, 4 dichlorophenyl) 1 methoxy 1 methylurea) (desmethoxy linuron), and 1( 3, 4 dichlorophenyl) urea) (norlinuron) 2 EFED currently has no monitoring data for these degradates in surface or groundwater.

The Tier II screening models PRZM 1 and EXAMS 2 with the Index Reservoir and Percent Crop Area adjustment (IR PCA PRZM/ EXAMS) were used to determine estimated surface water concentrations of the linuron metabolites listed above. The Screening Concentration in Groundwater (SCI GROW 3 ) model was used to estimate groundwater concentrations for linuron. Modeling results are shown in Table 1.

The IR PCA PRZM/ EXAMS modeling results indicate that desmethyl linuron, desmethoxy linuron and norlinuron have the potential to contaminate surface waters by spray drift, and runoff in areas with large amounts of annual rainfall. 3 Environmental Fate and Transport Assessment Although the environmental fate data base for parent linuron is essentially complete, two environmental fate data requirements (leaching/ adsorption/ desorption and terrestrial field dissipation studies) are not fulfilled. The environmental fate assessment for linuron is incomplete and tentative because information on the persistence, mobility and dissipation pathways of several degradates of linuron is not available.

Parent linuron appears to be moderately persistent and relatively immobile. Increased mobility may occur under specific environmental conditions such as in coarse textured soils and soils with low levels of organic matter. Linuron dissipates principally by biotic processes such as microbial degradation. In surface soils with adequate organic matter, the combined processes of adsorption and microbial degradation would limit linuron's potential to migrate to ground water. Linuron could runoff to surface water bodies. In that case, it would degrade fairly rapidly to three primary metabolites (desmethoxy linuron, desmethyl linuron, norlinuron, and 3,4 DCA, none of each is >10% of the applied linuron in the aerobic soil metabolism study). However, information on the persistence and mobility of these degradates is not currently available.

Linuron exhibits some of the properties and characteristics of chemicals that have been detected in ground water, and linuron itself has been detected in ground water in four states (Georgia, Missouri, Virginia and Wisconsin). Linuron is moderately persistent with an aerobic soil metabolism half life ranging from 57 to 100 days. Because linuron is sufficiently persistent and may be mobile under certain environmental conditions, it has the potential to impact ground water quality.

Linuron can be applied aerially or by ground spray and therefore could contaminate surface waters through spray drift. It has the potential to be somewhat persistent in surface waters, particularly those with low microbiological activity and long hydrological residence times. In a lab study, linuron degraded with a half life of less than 3 weeks in nonsterile anaerobic silt loam and sand soil: water (1: 1) systems. It may be less persistent in water and sediment under anaerobic conditions than under aerobic conditions. Its bioconcentration potential is relatively low.

Linuron is not currently regulated under the Safe Drinking Water Act, and water supply systems are not required to sample 4 and analyze for it. The primary treatment processes employed by most water systems may not always be completely effective in removing linuron's degradates. As a result, the Agency does have some moderate concerns regarding potential risks of these degradates to surface water source supply systems.

Surface Water Monitoring The EFED currently has no monitoring data on the concentrations of desmethyl linuron, desmethoxy linuron or nor linuron in surface water.

Modeling Tier II surface water modeling was done using the Index Reservoir (IR) scenario and Percent Crop Area (PCA) factor applied after modeling.

The index reservoir represents a potentially vulnerable drinking water source based on the geometry of an actual reservoir and its watershed in a specific area (Illinois), using regional screening specific cropping patterns, weather, soils, and other factors.

The PCA is a generic watershed based adjustment factor which represents the portion of a watershed planted to a crop or crops and will be applied to pesticide concentrations estimated for the surface water component of the drinking water exposure assessment using PRZM/ EXAMS with the index reservoir scenario.

EFED has limited fate and mobility data on these metabolites; thus, a combined residue approach was used to calculate their aerobic soil metabolism half lives (assuming equal toxicity) by the summation of the concentrations of the parent and its metabolites. The IR PCA PRZM/ EXAMS model use and fate input parameters for linuron in surface water are shown in Table 2. The IR PCA PRZM/ EXAMS model input and output files for linuron are shown in Appendix I.

*: Preliminary modeling using Kd of 0 and 2.7 resulted in little difference in EEC's. A Kd of 0 was used in this assessment as a worse scenario condition. 6 Assumptions and Uncertainties 11,12 In general, the use of input parameter values for the parent may increase the uncertainties in this assessment.

Index Reservoir The Index reservoir represent potential drinking water exposure from a specific area (Illinois) with specific cropping patterns, weather, soils, and other factors. Use of the index reservoir for areas with different climates, crops, pesticides used, sources of water (e. g. rivers instead of reservoirs, etc), and hydrogeology creates uncertainties. In general, because the index reservoir represents a fairly vulnerable watershed, the exposure estimated with the index reservoir will likely be higher than the actual exposure for most drinking water sources. However, the index reservoir is not a worst case scenario, communities that derive their drinking water from smaller bodies of water with minimal outflow, or with more runoff prone soils would likely get higher drinking water exposure than estimated using the index reservoir. Areas with a more humid climate that use a similar reservoir and cropping patterns may also get more pesticides in their drinking water than predicted using this scenario.

PRZM/ EXAMS uses the characteristics of a single soil to represent the soil in the basin. In fact, soils can vary substantially across even small areas, and this variation is not reflected in these simulations.

PRZM/ EXAMS does not consider tile drainage. Areas that are prone to substantial runoff are often tile drained. Tile drainage contributes additional water and in some cases, additional pesticide loading to the reservoir. This may cause either an increase or decrease in the pesticide concentration in the reservoir. Tile drainage also causes the surface soil to dry out faster. This will reduce runoff of the pesticide into the reservoir. The watershed used as the model for the index reservoir (Shipman City Lake) does not have tile drainage in the cropped areas.

EXAMS is unable to easily model spring and fall turnover. Turnover occurs when the temperature drops in the fall and the thermal stratification of the reservoir is removed. Turnover occurs again in the spring when the reservoir warms up. This results in complete mixing of the chemical through the water column at these times. Because of this inability, the Index Reservoir has been simulated without stratification. There is 7 data to suggest that Shipman City Lake, upon which the Index Reservoir is based, does indeed stratify in the deepest parts of the lake at least in some years. This may result in over or underestimation of the concentration in drinking water depending upon the time of the year and the depth the drinking water intake is drawing from.

Percent Crop Area Correction Factor The PCA is a watershed based modification. Implicit in its application is the assumption that currently used field scale models reflect basin scale processes consistently for all pesticides and uses. In other words, we assume the field scale processes simulated by the coupled PRZM and EXAMS models are a reasonable approximation of pesticide fate and transport within a watershed that contains a drinking water reservoir. If the models fail to capture pertinent basin scale fate and transport processes consistently for all pesticides and all uses, the application of a factor that reduces the estimated concentrations predicted by modeling could, in some instances, result in inadvertently passing a chemical through the screen that may actually pose a risk. Some preliminary assessments made in the development of the PCA suggest that PRZM/ EXAMS may not be realistically capturing basin scale processes for all pesticides or for all uses. A preliminary survey of water assessments which compared screening model estimates to readily available monitoring data suggest uneven model results. In some instances, the screening model estimates are more than an order of magnitude greater than the highest concentrations reported in available monitoring data; in other instances, the model estimates are less than monitoring concentrations. Because of these concerns, the Science Advisory Panel (SAP) recommended using the PCA only for "major" crops in the Midwest. For other crops, development of PCA's will depend on the availability of relevant monitoring data that could be used to evaluate the result of the PCA adjustment.

The spatial data used for the PCA came from readily available sources and have a number of inherent limitations:

° The size of the 8 digit HUC [mean = 366,989 ha; range = 6.7 2,282,081 ha; n = 2,111] may not provide reasonable estimates of actual PCA's for smaller watersheds. The watersheds that drain into drinking water reservoirs are generally smaller than the 8 digit HUC and may be better represented by watersheds defined for drinking water intakes. 8 ° The conversion of the county level data to watershed based percent crop areas assumes the distribution of the crops within a county is uniform and homogeneous throughout the county area. Distance between the treated fields and the water body is not addressed. ° The PCA's were generated using data from the 1992 Census of Agriculture. However, recent changes in the agriculture sector from farm bill legislation may significantly impact the distribution of crops throughout the country. The methods described in this report can rapidly be updated as more current agricultural crops data are obtained. The assumption that yearly changes in cropping patterns will cause minimal impact needs to be evaluated.

The PCA adjustment is only applicable to pesticides applied to agricultural crops. Contributions to surface waters from nonagricultural uses such as urban environments are not wellmodeled Currently, non agricultural uses are not included in the screening model assessments for drinking water.

The PCA does not consider percent crop treated because detailed pesticide usage data are extremely limited at this time. Detailed pesticide usage data are currently available for only a few states.

Groundwater Monitoring The EFED has no monitoring data on the concentrations of desmethyl linuron, desmethoxy linuron or nor linuron in groundwater at the present time.

There is a possibility that those metabolites were not intended to look for, or they might have been present at concentrations lower than that of the instruments used for the water samples collected The SCI GROW model was used to estimate potential groundwater concentrations of linuron.

Table 3 shows the input parameter values used in SCI GROW modeling.

Groundwater EECs predicted using the SCI GROW screening model are substantially less than those estimated for surface water using PRZM and EXAMS. However, persistence in groundwater should be longer.

I. Self-Regulatory Organization's Statement of the Terms of Substance
of the Proposed Rule Change

    The Exchange proposes to amend NYSE Rule 123A.30 to permit certain
convert-and-parity (``CAP'') orders to trade on parity with other limit
orders, including orders entered through NYSE's Designated Order
Turnaround (``DOT'') system[supreg]. The text of the proposed rule
change is available at the Exchange, the Commission's Public Reference
Room, and www.nyse.com.

II. Self-Regulatory Organization's Statement of the Purpose of, and
Statutory Basis for, the Proposed Rule Change

    In its filing with the Commission, the Exchange included statements
concerning the purpose of, and basis for, the proposed rule change and
discussed any comments it received on the proposed rule change. The
text of these statements may be examined at the places specified in
Item IV below. The Exchange has prepared summaries, set forth in
Sections A, B, and C below, of the most significant aspects of such
statements.

A. Self-Regulatory Organization's Statement of the Purpose of, and
Statutory Basis for, the Proposed Rule Change

1. Purpose
    This rule filing effects an amendment to NYSE Rule 123A.30, which,
together with NYSE Rule 1000, governs the automatic execution of CAP
orders. The amendment permits passively converted CAP orders--that is,
CAP orders that are converted by the specialist for the purpose of
bidding or offering--to trade on parity with other limit orders,
including DOT system orders that were on NYSE's Display Book[supreg] at
the time of the conversion and could trade on the same side of the
market and at the same price as the converted CAP orders. Before this
amendment, CAP orders were placed in the same parity group as DOT
orders for purposes of parity allocations among all orders upon
execution. Within that parity group, those DOT orders had priority over
the converted CAP orders.
a. Background
    The Exchange states that CAP orders are not actually live orders,
but rather are memoranda of orders that can be made live either
automatically via an electing trade (a trade at a price that
automatically triggers the CAP order to become a live order and
immediately execute at the triggering price) or manually via conversion
by the specialist. In the latter situation, the specialist converts the
CAP into a limit order, and bids or offers on behalf of that order
(referred to as a ``passive conversion''). Thereafter, a trade may take
place against some or all of the converted CAP order; any portions that
are not executed may be ``unconverted'' and revert to their status as
CAP orders.
    The Exchange states that, although they are not live orders, CAP
orders nevertheless represent public customer interest in which the
customer has consented to trading on parity with the specialist when
they are either elected or converted. Because CAP orders are linked,
either through election or conversion, to other customer interest at a
given price, CAP orders give customers a way to participate in trades--
that is, to ``go along'' with other interest at a price--but protect
them from either initiating a trade or constituting 100% of one side of
a trade.
    The Exchange states that, at the time that specialists were given
the ability to passively convert CAP orders as agents for customers,
the Commission was concerned that specialists not have unfettered
discretion in representing those orders; although the Commission
recognized that the specialist could exercise some degree of control
over the timing and size of the conversions, the Commission insisted
on, and the Exchange agreed to implement, certain restrictions that
would prevent the specialist from misusing CAP orders to drive the
price of a security up or down inappropriately.\6\ Among these
restrictions was the requirement that passively converted CAP orders
could not be executed before ``conventional'' limit orders, e.g., DOT
orders, that were on the Display Book at the time of the conversion and
could trade at the same price and on the same side as the converted CAP
order.
---------------------------------------------------------------------------

    \6\ See Securities Exchange Act Release No. 24505 (May 22,
1987), 52 FR 20484 (June 1, 1987) (SR-NYSE-1985-01).

---------------------------------------------------------------------------

b. Amendment to NYSE Rule 123A.30
    The instant proposal would change the treatment of passively
converted CAP orders to permit the CAP orders to trade as a group on
parity with other agency interest, including same-side same-price DOT
orders (i.e., DOT orders that can trade on the same side of the market
and at the same price as the CAP orders). The Exchange states that the
proposed rule change is necessitated by other changes that the Exchange
is making that will permit market participants to enter non-displayed
reserve interest directly into the Display Book.
    As initially implemented, under Rule 123A.30, passively converted
CAP orders were combined with DOT orders for purposes of determining
the overall parity allocation in any trade; this so-called ``DOT
group'' was treated as a single agent in the parity divisor. Thus, for
example, in an execution involving two brokers' orders, DOT orders, and
passively converted CAP orders, all on parity, the DOT group and the
brokers would each be allocated one-third of the traded shares, even
though the DOT group contained two different customer groups
(conventional limit orders and passively converted CAP orders). The
Exchange's system would then internally allocate shares within the DOT
group in time priority. As a consequence of this allocation
methodology, passively converted CAP orders did not receive allocations
until all DOT orders that were on the Display Book at the time of the
conversion were satisfied in full.
    As noted above, NYSE implemented foundational changes to its
systems that permit customers to enter undisplayed reserve orders from
off-Floor directly into the Display Book through DOT (previously, only
Floor brokers could enter undisplayed reserve interest on behalf of
customers).\7\ Such off-Floor reserve interest will be included in the
DOT group for purposes of parity allocations when there is a trade and,
despite being non-displayed, would within that DOT group, currently be
entitled to priority over passively converted CAP orders.
---------------------------------------------------------------------------

    \7\ See Securities Exchange Act Release Nos. 57792 (May 7,
2008), 73 FR 27601 (SR-NYSE-2008-36) and 57688 (April 18, 2008), 73
FR 22194 (SR-NYSE-2008-30).
---------------------------------------------------------------------------

    NYSE has determined that it is not feasible at this time to have
the system differentiate between displayed DOT interest and non-
displayed DOT interest when doing parity allocations. This could result
in two unintended consequences vis-[agrave]-vis passively converted CAP
orders: First, the changes will result in non-displayed interest (DOT
reserves) taking priority over displayed interest (passively converted
CAP orders); and second, if there is substantial interest in reserve,
the change will make it difficult (if not impossible) for passively
converted CAP orders to receive an execution, since all displayed and
non-displayed DOT interest would need to be satisfied first.
    The Exchange has further determined that it is not feasible to undo
the various foundational programming changes necessary to implement
off-Floor reserves in the near future. To address these issues, the
Exchange is proposing to amend NYSE Rule 123A.30 to change the parity
allocation methodology. Under the proposed rule change, passively
converted CAP orders would become their own parity group for purposes
of the parity divisor. For example, in the execution described above,
involving two brokers, DOT orders and passively converted CAP orders,
each group would receive one-fourth of the executed shares, instead of
the DOT orders and CAP orders sharing a one-third allocation.
    The Exchange believes that the instant proposal is appropriate
because fundamental changes in the market--both in terms of market
structure and in terms of the behavior of market participants--have
made it significantly less likely that specialists could or would use
passively converted CAP orders to engage in manipulative or
destabilizing conduct.
    The Exchange states that, among other things, the restrictions on
passive CAP conversions were implemented at a time when NYSE enjoyed a
market share in excess of 80% of transactions in its listed securities.
Today, NYSE market share is approximately half that amount. The
Exchange states that, where the specialist once had substantial
influence over the price of a stock, and could extend his influence
further through the misuse of CAP orders, the specialist today has
significantly less influence over the price of a stock.
    According to the Exchange, market share aside, the process of
converting CAP orders also impedes the specialist's ability in an
automated market to misuse CAP orders to drive the market. Passive
conversions must be conducted by the specialist manually. The Exchange
states that, because of the increased automation of modern markets, and
the resulting exponential increase in the pace of trading over years
past, the delay inherent in a manual process further erodes the
possibility that a specialist could realistically use the passive
conversion of CAP orders to manipulate the market.
    The Exchange believes that a specialist's ability to drive the
market through CAP conversions is further diminished simply by the fact
that the number of customers using CAP orders has dropped off
substantially. For example, during March 2008, there was an average of
2,125 conversions per day across the entire NYSE Floor, as compared to
4,401 conversions per day during October 2007 and 6,762 conversions
during June 2007. More tellingly, the average number of passive
conversions during 2008 (an average of 2,484 conversions per day, year-
to-date) represented only .0004% of quotes initiated per day by
specialists (``s-quotes'') during the same period,\8\ and .000045% of
all quotes disseminated per day overall.\9\ Therefore, the Exchange
believes that the likelihood that a specialist could misuse a passive
conversion to affect prices is small.
---------------------------------------------------------------------------

    \8\ Specialists have averaged 5,268,000 s-quotes per day during
2008.
    \9\ NYSE has disseminated an average of 54,201,000 quotes per
day during 2008.
---------------------------------------------------------------------------

    According to the Exchange, the sharp reduction in the number of CAP
orders reflects the increased popularity of reserve orders, which
permit customers to achieve the same go-along benefits of CAP orders,
but retain greater control of the pricing of their orders.
Significantly, despite the fact that reserve interest and CAP orders
can perform similar functions, they receive disparate parity treatment:
reserve interest trades on parity,\10\ while CAP interest does not.
---------------------------------------------------------------------------

    \10\ See NYSE Rule 70.20.
---------------------------------------------------------------------------

    Finally, the Exchange states that it is also important to keep in
mind that, under the current scheme, CAP orders, although they
represent public customer orders, are penalized in their parity
treatment for no other reason than that they have been entrusted to the
specialist for execution. When the specialist had outsized influence in
the market, this was arguably appropriate because, in return for
inferior parity treatment, CAP orders received the benefit of the
specialist's knowledge of the market and expertise on the optimal time
to bid or offer. But in today's environment, where market fragmentation
has reduced the specialist's ability to know the overall market, the
Exchange believes this trade-off no longer makes sense. Accordingly,
the proposed rule change would eliminate this disadvantage to CAP
orders. At the same time, the proposal would not eliminate all
disadvantages to CAP order relative to e-Quotes: all passively
converted CAP orders would share one slice of the allocation on an
execution, whereas

brokers using e-Quotes each take their own slice. Thus, the parity
divisor is being increased by one, though only on executions where: (1)
There are passively converted CAP orders being bid or offered; and (2)
the execution size is in an amount less than necessary to completely
fill all orders at that price. The Exchange states that, because this
will be the case only a very few times per day (fewer than once per day
per stock, on average), it does not believe that the potential harm to
DOT orders is significant.
    In short, given the ways in which liquidity has been fractured
among markets, the sharply reduced number of conversions today, the
disparate treatment of passively converted CAP orders and reserve
interest, and the automation of markets making manual trades
commensurately more difficult, the Exchange believes that: (1) The harm
of manipulation-by-passive-conversion that NYSE set out to protect
against in 1985 is not present today; and (2) when weighed against the
fact that CAP orders are agency orders on behalf of public customers
just as DOT orders are, it does not seem appropriate to continue to
discriminate against the passively converted CAP orders by forcing them
to step behind the DOT orders.
    For these reasons, NYSE proposes to eliminate the restriction on
giving passively converted CAP orders parity with other limit orders,
including resting DOT orders.
2. Statutory Basis
    The Exchange believes that the proposed rule change is consistent
with Section 6(b) of the Act,\11\ in general, and furthers the
objectives of Section 6(b)(5) of the Act,\12\ in particular, in that it
is designed to prevent fraudulent and manipulative acts and practices,
to promote just and equitable principles of trade, to foster
cooperation and coordination with persons engaged in facilitating
transactions in securities, and to remove impediments to and perfect
the mechanism of a free and open market and a national market system.
As described more fully above, the proposed rule change is intended to
ensure fair treatment of displayed public orders (passively converted
CAP orders) in connection with changes being made to other Exchange
systems to permit customers to directly place non-displayed interest
into the Display Book. In addition, the Exchange believes that in view
of both the substantial changes to the marketplace and the Exchange
since the original rule was adopted, and the paucity of affected
orders, the proposed change does not substantially affect the public
interest or unreasonably disadvantage another group of public
customers. Conversely, without the proposed rule change, the Exchange
states that there is a substantial risk that a group of public
customers would be shut out of the market entirely, or would receive an
inferior treatment vis-[agrave]-vis non-displayed interest, which the
Exchange believes is contrary to the policy of the Commission regarding
rewarding customers willing to display liquidity in the market.

B. Self-Regulatory Organization's Statement on Burden on Competition

    The Exchange does not believe that the proposed rule change will
impose any burden on competition that is not necessary or appropriate
in furtherance of the purposes of the Act.

C. Self-Regulatory Organization's Statement on Comments on the Proposed
Rule Change Received From Members, Participants, or Others

    The Exchange states that written comments on the proposed rule
change were neither solicited nor received.

III. Date of Effectiveness of the Proposed Rule Change and Timing for
Commission Action

    Because the foregoing proposed rule change: (1) Does not
significantly affect the protection of investors or the public
interest; (2) does not impose any significant burden on competition;
and (3) by its terms does not become operative for 30 days after the
date of this filing, or such shorter time as the Commission may
designate if consistent with the protection of investors and the public
interest, the proposed rule change has become effective pursuant to
Section 19(b)(3)(A) of the Act \13\ and Rule 19b-4(f)(6)
thereunder.\14\

along with a brief description and text of the proposed rule change,
at least five business days prior to the date of filing of the
proposed rule change, or such shorter time as designated by the
Commission. The Exchange has fulfilled this requirement.
---------------------------------------------------------------------------

    A proposed rule change filed under Rule 19b-4(f)(6) normally does
not become operative for 30 days after the date of filing. However,
Rule 19b-4(f)(6)(iii) permits the Commission to designate a shorter
time if such action is consistent with the protection of investors and
the public interest. The Commission notes NYSE's representation
regarding its determination that it is not feasible at this time to
have the Exchange's system differentiate between displayed DOT interest
and non-displayed DOT interest when doing parity allocations.
Accordingly, given the fact that CAP orders represent customer orders,
the Commission believes that waiving the 30-day operative delay is
consistent with the protection of investors and the public
interest.\15\
---------------------------------------------------------------------------

    \15\ For purposes only of waiving the 30-day operative delay,
the Commission has also considered the proposed rule's impact on
efficiency, competition, and capital formation. See 15 U.S.C.
78c(f).
---------------------------------------------------------------------------

    At any time within 60 days of the filing of the proposed rule
change, the Commission may summarily abrogate such rule change if it
appears to the Commission that such action is necessary or appropriate
in the public interest, for the protection of investors, or otherwise
in furtherance of the purposes of the Act.\16\
---------------------------------------------------------------------------

    \16\ 15 U.S.C. 78s(b)(3)(C). For purposes of calculating the 60-
day period within which the Commission may summarily abrogate the
proposal, the Commission considers the period to commence on May 16,
2008, the date on which the Exchange submitted Amendment No. 1.
---------------------------------------------------------------------------

Coast Guard

33 CFR Part 117

[Docket No. USCG-2017-0411]

Drawbridge Operation Regulation; Gulf Intracoastal Waterway,
Galveston, TX

AGENCY: Coast Guard, DHS.

ACTION: Notice of deviation from drawbridge regulation.

-----------------------------------------------------------------------

SUMMARY: The Coast Guard has issued a temporary deviation from the
operating schedule that governs the Galveston Causeway Railroad
Vertical Lift Bridge across the Gulf Intracoastal Waterway (GIWW), mile
357.2 West of Harvey Locks (WHL), at Galveston, Galveston County,
Texas. The deviation is necessary to replace decking on the bridge.
This deviation allows the bridge to remain in the closed-to-navigation
position during the deviation period.

DATES: This deviation is effective from 7:30 a.m. on June 5, 2017
through 4:30 p.m. on June 8, 2017.

ADDRESSES: The docket for this deviation, [USCG-2017-0411] is available

SUPPLEMENTARY INFORMATION: The Burlington Northern Santa Fe Railway
Company requested a temporary deviation from the operating schedule of
the Galveston Causeway Railroad Vertical Lift Bridge across the GIWW,
mile 357.2 WHL, at Galveston, Galveston County, Texas. The bridge has a
vertical clearance of 8.0 feet above mean high water, elevation 3 feet
of the North American Vertical Datum of 1988 (NAVD88) in the closed-to-
navigation position, and 73 feet above mean high water in the open-to-
navigation position. This bridge is governed by 33 CFR 117.5.
    This deviation was requested to allow the bridge owner to replace
decking

caused by a derailment in February. This deviation allows the vertical
lift bridge to remain in the closed-to-navigation position from 7:30
a.m. to 11 a.m. and from 1 p.m. to 4:30 p.m., daily, beginning June 5
through June 8, 2017, with a scheduled two-hour opening each day to
facilitate passage of vessel traffic from 11 a.m. to 1 p.m., and the
bridge will revert to open on demand status at 4:30 p.m. each day.
    Navigation at the site of the bridge consists mainly of tows with
barges and some recreational pleasure craft. The bridge can open in
case of emergency. No alternate routes are available. The Coast Guard
will inform the users of the waterway through our Local and Broadcast
Notices to Mariners of the change in operating schedule for the bridge
so that vessel operators can arrange transits to minimize any impact
caused by the temporary deviation.
    In accordance with 33 CFR 117.35(e), the drawbridge must return to
its regular operating schedule immediately at the end of the effective
period of this temporary deviation. This deviation from the operating
regulations is authorized under 33 CFR 117.35.

    Dated: May 31, 2017.
Eric A. Washburn,
Bridge Administrator, Eighth Coast Guard District.

Records Governing Off-the-Record Communications; Public Notice

    This constitutes notice, in accordance with 18 CFR 385.2201(b), of
the receipt of prohibited and exempt off-the-record communications.
    Order No. 607 (64 FR 51222, September 22, 1999) requires Commission
decisional employees, who make or receive a prohibited or exempt off-
the-record communication relevant to the merits of a contested
proceeding, to deliver to the Secretary of the Commission, a copy of
the communication, if written, or a summary of the substance of any
oral communication.
    Prohibited communications are included in a public, non-decisional
file associated with, but not a part of, the decisional record of the
proceeding. Unless the Commission determines that the prohibited
communication and any responses thereto should become a part of the
decisional record, the prohibited off-the-record communication will not
be considered by the Commission in reaching its decision. Parties to a
proceeding may seek the opportunity to respond to any facts or
contentions made in a prohibited off-the-record communication, and may
request that the Commission place the prohibited communication and
responses thereto in the decisional record. The Commission will grant
such a request only when it determines that fairness so requires. Any
person identified below as having made a prohibited off-the-record
communication shall serve the document on all parties listed on the
official service list for the applicable proceeding in accordance with
Rule 2010, 18 CFR 385.2010.
    Exempt off-the-record communications are included in the decisional
record of the proceeding, unless the communication was with a
cooperating agency as described by 40 CFR 1501.6, made under 18 CFR
385.2201(e)(1)(v).
    The following is a list of off-the-record communications recently
